Pekr: 12-Nov-2012	Create 2 files. Call the first one e.g. cgi-test.html, and upload it to your server. The only thing you have to change is the link to your .cgi script in there: <HTML> <TITLE>Simple Web Form</TITLE> <BODY> <b>Simple Web Form</b><p> <FORM ACTION="http://www.xidys.com/cgi-bin/cgi-test.cgi"> <INPUT TYPE="TEXT" NAME="Field" SIZE="25"><BR> <INPUT TYPE="SUBMIT" NAME="Submit" VALUE="Submit"> </FORM> </BODY> </HTML> Create a second file, called cgi-test.cgi (it has to align to how you name it in the above source file). Upload it to your cgi working directory. Remember to change the first line to contain the path, where your REBOL executable is placed: #!/usr/local/bin/rebcmd -sqc REBOL [] print join "Content-type: text/plain" newline start: now/time/precise submitted: decode-cgi read-cgi values: construct submitted prin "Submitted: " print mold submitted prin "values: " print mold values prin "values/field: " print mold values/field print now/time/precise - start print newline Now go to your URL, and try to submit some values. You can test it on my site at: http://www.xidys.com/cgi-test.html

Gabriele: 11-Mar-2006	Carl: "I would really like to have a DB built-into REBOL 3.0 The trick is, it cannot just be any DB... it has to align perfectly with REBOL. Specifically, we want the DB to be able to store all REBOL datatypes efficiently. But, we also want the DB code to be very small. I will not allow REBOL to bloat for it. And, finally, the code must be free, like SQLite is (at least, I think). Note that the DB does not need to have every feature in the book. I'm not asking for SQL (that is, we will use REBOL or a dialect to access the DB, no need for another language). I would really like to get the help of the community in this effort, but I do not have time to even organize a decent search. If someone else wants to head it up, it would very much improve R3.0. If not, then we will do RIF, which gets us a lot of DB, and is super efficient compared to any other DB. But, it is only an index system, not a RDB."

Brock: 11-Jul-2006	My two cents, in this case you should have a way to either tell the field not to disappear. Maybe align the text followed by the field ie. Search [______] , or add/change this option to represent the icon and text horizontally and force the face portion to remain on screen when the 'Text' view mode is selected.

PeterD: 29-May-2007	Dear Anton, A mezzanine, that's it. I can not tell you how frustrated I am. See my response to Gabriele below: Thanks for the info. It is so sad to see that "little" things are not fixed in a reasonable fashion. Here I am, 99% of my stuff is Center aligned and I find myself "regretting" that I go for a "not so established" language. (never thought that entering text in a box will be a problem) I have to actually ask 1000 people to klick 4 times more often, just to overcome a stupid bug. So I ask them to: Change to left align Edit Go back to Center align Repeat as long as needed and pardon, I used "REBOL" Best regards So, what is needed to fix this, please let's include Ashley Thanks a ton for the shimmer of light I see at the end of the tunnel Peter

RobertS: 1-Apr-2008	Diss'ing IDE's might alienate some Smalltalk folk. I cannot imagine maintaining an application suite such as I deal with everyday without an IDE. I just wish it was not eclipse ... Of course only wimps used a Disk Operating System and real men code in machine codes only ... and real pro's dictated their SNOBOL punch cards to lovely assistants ... and ANT scripts are for sissies. Some must have ridiculed Tcl, Expect and TK in their day ... but if my IDE can facilitate my efforts to systematically (key word there) shrirnk company''s codebase as it becomes more reliable with better test coverage then maybe a refactoring browser would be a good tool after all. Even better if it is an integrated part of the IDE, as in Dolphin Smalltalk or Squeak Smalltalk or Smalltalk/X or Cincom Visual Smalltalk. Not that I couldn't survive on grep and diff's. But once the codebase is too large for any one person to author or maintain on their lonesome, a tool that remebers what you did last and where can be a god-send. If you want to know hell without an IDE join an actuarial department working in APL. There you don't even know if they have talent: you just hope most of it works as each quarter rolls around and try to survive year-end. But you know they're smart, cuz after all, they're actuaries - and look at all that APL code in all those files ... of course a few of them look back wistfully at their student days in C with Borland's decent IDE.

Whether the progress will continue depends on the feedback. ---All Rights Reserved The work is based on the documentation of REBOL View provided by REBOL Technology and its mailing list. All rights to this documentation remain the property of REBOL Technology. ---Plagiarized Examples Things are shamelessly plagiarized. There are many experts on the mailing list whose work is included here; most notably the examples from the REBOL documentation. ---Approach The approach that this document uses is to use REBOL/View/VID to demonstrate its abilities and give a visual tutorial. To enable this some changes have been made to the core %easyvid.r program from Carl Sassenrath. A scoll bar was added to the right pane because it was just too difficult to constrain the examples to the screen real estate that was available. ---Order Order The order of the items needs some work. The easyvid presentation approach today does not allow for the drilling down and expansion of an outline tree which is needed for a large amount of documentation. The preferred approach is to put a multi-level tree for navigation purposes and then allow navigation up and down the tree. ===To Do * make this a true outline tree * re-organize it better * update as requested and as possible by suggestions on AltME's REBOL world under group EasyVID * correct numerous flaws * better scrolling implementation using the updates that have been used in other examples such as Didier's %delete-email.r * allow clipping to clipboard like AltME does on a row for the source examples ===Introduction to VID With REBOL/View it's easy and quick to create your own user interfaces. The purpose of this tutorial is to teach you the basic concepts or REBOL/View interfaces in about 20 minutes. VID is REBOL's Visual Interface Dialect. A dialect is an extension of the REBOL language that makes it easier to express or describe information, actions, or interfaces. VID is a dialect that provides a powerful method of describing user interfaces. VID is simple to learn and provides a smooth learning curve from basic user interfaces to sophisticated distributed computing applications. ---Creating VID Interfaces VID interfaces are written in plain text. You can use any text editor to create and edit your VID script. Save your script as a text file, and run it with REBOL/View. !Note: Using a word processor like Word or Wordpad is not recommended because files are not normally saved as text. If you use a word processor, be sure to save the output file as text, not as a document (.doc) file. Recommendation: Look at TextPad from http://www.textpad.com ===Minimal VID Example Here is a minimal VID example. It creates a window that displays a short text message. Only one line of code is required: view layout [text "Hello REBOL World!"] You can type this line at the REBOL console prompt, or save it in a text file and run it with REBOL. If you save it as a file, the script will also need a REBOL header. The header tells REBOL that the file contains a script. Here is an example of the script file with a header: REBOL [Title: "Example VID Script"] view layout [text "VID Example!"] You can also add buttons and other gadgets to the script. The example below displays a text, list of files, and a button: view layout [ h2 "File List:" text-list data read %. button "Great!" ] !Click on the examples above to see how they will appear on your screen. Click on their close box to remove them. All of the examples that follow can be viewed this way. ===Window Management The code that displays the examples also shows how to manage the number of windows that are open. Look at the show-example block in the code near the end of this script. The location of the example window is also managed here by keeping track of the co-ordinates for the sample. After the sample window is moved, the next use will open at the same location. ===Pre-loaded Images For this script, the image which represented a Portable Network Graphic definition of an image is held in the script and loaded. For a small number of graphics, this can achieve some packaging and performance benefits. The image "polished" is used through the script to achieve the polished steel look that is one the outer frame. backtile polished orange button 200x50 "Polished Steel Look" polished ===Two Basic Functions Two functions are used to create graphical user interfaces in REBOL: VIEW and LAYOUT. The LAYOUT function creates a set of graphical objects. These objects are called faces. You describe faces with words and values that are put into a block and passed to the LAYOUT function. The VIEW function displays faces that were previously created by LAYOUT. The example below shows how the result of the LAYOUT function is passed to the VIEW function, and the interface is displayed. view layout [ text "Layout passes its result to View for display." button "Ok" ] Click on the above example to view it. !Note: the block provided to a layout is not normal REBOL code, it is a dialect of REBOL. Using a dialect makes it much easier to express user interfaces. ===Styles Styles describe faces. The examples above use the text and button styles to specify a text line and a button. REBOL has 40 predefined face styles. You can also create your own custom styles. Here are a few example styles: view layout [ h1 "Style Examples" box brick 240x2 vtext bold "There are 40 styles built into REBOL." button "Great" toggle "Press" "Down" rotary "Click" "Several" "Times" choice "Choose" "Multiple" "Items" text-list 120x80 "this is" "a list" "of text" across check radio radio led arrow below field "Text Entry" ] The words like backdrop, banner, box, text, and button are styles. ===Facets Facets let you modify a style. For instance, you can change the color, size, text, font, image, edge, background, special effects, and many other facets of a style. Facets follow the style name. Here is an example that shows how you modify the text style to be bold and navy blue: view layout [txt bold navy "Facets are easy to use."] The words bold and navy are not styles. They are facets that modify a style. Facets can appear in any order so you don't have to remember which goes first. For example, the line above could be written as: view layout [txt "Facets are easy to use." navy bold] Many facets that can be specified. Here is an example that creates bold red text centered in a black box. view layout [txt 300 bold red black center "Red Text"] You can create facets that produce special effects, such as a gradient colored backdrop behind the text: view layout [ vtext bold "Wild Thing" effect [gradient 200.0.0 0.0.200] ] ===Custom Styles Custom styles are shortcuts that save time. When you define a custom style, the facets you need go into the new style. This reduces what you need to specify each time you use the style, and it allows you to modify the look of your interface by changing the style definitions. For example, here is a layout that defines a style for red buttons. The style word defines the new style, followed by the old style name and its facets. view layout [ style red-btn button red text "Testing red button style:" red-btn "Test" red-btn "Red" ] So, if you wanted to create a text style for big, bold, underlined, yellow, typewriter text: view layout [ style yell tt 220 bold underline yellow font-size 16 yell "Hello" yell "This is big old text." yell "Goodbye" ] ===Master Stylesheet REBOL holds its styles in a master stylesheet. When you are sure that you want to share them without having to add the style sheet line then do it as follows: First add the style to the master sheet: button 200x50 "Define text-note as maroon bold text" [stylize/master [ text-note: txt maroon bold ]] button 200x50 "Define text-note as white italic text" [stylize/master [ text-note: txt white italic ]] Then invoke it: view layout [ across size 200x200 return text-note "This shows a master stylesheet style in use." return text-note "This shows another usage of the same style." return text-note "If you want to see the other style displayed, click the Add Style section again and then use the other button" ] ===Note About Examples !From this point forward, all examples will assume that the view and layout functions are provided. Only the layout block contents will be shown. To use these examples in your scripts, you will need to put them in a layout block, as was shown earlier. For example, code that is written as: view layout [button red "Test it"] will now appear as: button red "Test it" ===Face Sizes The size of a face depends on its style. Most styles, such as buttons, toggles, boxes, checks, text-lists, and fields, have a convenient default size. Here are some examples. button "Button" toggle "Toggle" box blue field text-list If no size is given, text will automatically compute its size, and images will use whatever their source size is: text "Short text line" text "This is a much longer line of text than that above." image %palms.jpg You can change the size of any face by providing a size facet. The size can be an integer or a pair. An integer specifies the width of the face. A pair specifies both width and height. Images will be stretched to fit the size. button 200 "Big Button" button 200x100 "Huge Button" image %palms.jpg 50x50 image %palms.jpg 150x50 ===Color Facets Most styles have a default color. For example the body of buttons will default to a teal color. To modify the color of a face, provide a color facet: button blue "Blue Button" h2 red "Red Heading" image %palms.jpg orange Colors can also be specifed as tuples. Each tuple contains three numbers: the red, green, and blue components of the color. Each component can range from 0 to 255. For example: button 200.0.200 "Red + Blue = Magenta" 200 image %palms.jpg 0.200.200 "Green + Blue" Some face styles also allow more than one color. The effect of the color depends on the style. For text styles the first color will be used for the text and the second color for the background of the text: txt "Yellow on red background" yellow red banner "White on Navy Blue" white navy For other styles, the body of the face is the first color, and the second color will be used as its alternate. button "Multicolor" olive red toggle "Multicolor" blue orange ===Layout Commands To drop user interface elements on the canvas according to VIDs directional layout controls ---Across You are placing elements in a row orientation across return button "A" button "B" button "C" return button "D" button "E" button "F" ---Below You are placing elements in a column orientation below return button "A" button "B" button "C" return button "D" button "E" button "F" ---Mix You can mix the directional controls across return button "A" button "B" below button "C" across button "D" button "E" button "F" ---Padding The pad keyword creates extra padding between styles. It uses a pair or integer value. When it is an integer, spacing is created either horizontally (across) or vertically (below). When it is a pair, the spacing will be created both horizontal and vertically. The following example illustrates both uses. First, the buttons "one" and "two" are padded with an integer representing 40 pixels in one direction. Then the buttons "three" and "four" are padded with a pair representing 40x40 pixels. across button "one" pad 40 button "two" return button "three" pad 40x40 button "four" Padding can be negative. backtile polished orange pad 200x200 button "A" pad -100x-100 button "B" ---Guide A guide is a virtual alignment control title "Buttons Without A Guide" button "one" button "two" return button "three" button "four" return button" five" button "six" With an implicit guide location title "Buttons With An Implicit Guide Location" guide button "one" button "two" return button "three" button "four" return button" five" button "six" With an explicit guide location across title "Buttons With An Explicit Guide Location" guide 55x100 button "one" button "two" return button "three" button "four" return button" five" button "six" ===Tabstops Tabs can be used for alignment. ---Across tabs 200 ; sets tabs every 200 pixels across button 20 "A" tab button 20 "B" tab button 20 "C" tabs 100 ; sets tabs every 100 pixels return button 20 "D" tab button 20 "E" tab button 20 "F" ---Below tabs 200 ; sets tabs every 200 pixels below button 20 "A" tab button 20 "B" tab button 20 "C" tabs 100 ; sets tabs every 100 pixels return button 20 "D" tab button 20 "E" tab button 20 "F" ---Explicit Settings Tabstops can be set at explicit values tabs [100 124 166 212 300] across tab button 20 "A" tab button 20 "B" tab button 20 "C" tab button 20 "D" ===Color Facets Most styles have a default color. For example the body of buttons will default to a teal color. To modify the color of a face, provide a color facet: button 200 blue "Blue Button" h2 red "Red Heading" image polished orange Colors can also be specifed as tuples. Each tuple contains three numbers: the red, green, and blue components of the color. Each component can range from 0 to 255. For example: button 200.0.200 "Red + Blue = Magenta" 200 image polished 0.200.200 "Green + Blue" Some face styles also allow more than one color. The effect of the color depends on the style. For text styles the first color will be used for the text and the second color for the background of the text: txt "Yellow on red background" yellow red title "White on Navy Blue" white navy For other styles, the body of the face is the first color, and the second color will be used as its alternate. button 200 "Multicolor" olive red toggle 200 "Multicolor" blue orange From the mailing list, there was a problem reported in changing button color: view layout [ b: button "New color" [ b/color: random 255.255.255 show b ] ] And the answer was that the gradient of the color was preventing this change from working: style color-changing-button button 0.0.0 ; new style overwrites gradient effect b: color-changing-button "New color" [ b/color: random 255.255.255 show b ] ===Text Facets Most faces will accept text to be displayed. Even graphical faces can display text. For example, the box and image faces will display text if it is provided: box blue "Box Face" image polished "Image Face" Most button faces will accept more than one text string. The strings will be shown as alternates as the face is selected. button 200 "Up" "Down" toggle 200 "Off" "On" rotary 200 "Red" "Green" "Blue" "Yellow" choice 200 "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" text-list 200 "Monday" "Tuesday" "Wednesday" "Thursday" "Friday" When other datatypes need to be displayed as text, use the form function to convert them first: button 250 form now field form first read %. ===Normal Text Style Normal text is light on dark and can include a number of facets to set the font, style, color, shadow, spacing, tabbing, and other attributes. text "Normal" text "Bold" bold text "Italic" italic text "Underline" underline text "Bold italic underline" bold italic underline text "Big" font-size 32 text "Serif style text" font-name font-serif text "Spaced text" font [space: 5x0] Text also includes these predefined styles: title "Title" 200 vh1 "vh1" vh2 "vh2" vh3 "vh3" vh4 "vh4" label "Label" ===Document Text Style Document text is dark on light and can also include a number of facets to set the font, style, color, shadow, spacing, tabbing, and other attributes. txt "Normal" txt "Bold" bold txt "Italic" italic txt "Underline" underline txt "Bold italic underline" bold italic underline txt "Big" font-size 32 txt "Serif style text" font-name font-serif txt "Spaced text" font [space: 5x0] Document text also includes these predefined styles: title "Centered title" 200 h1 "Heading 1" h2 "Heading 2" h3 "Heading 3" h4 "Heading 4" tt "Typewriter text" ===Text Entry Fields Text input fields accept text until the enter or tab key is pressed. A text input field can be created with: field To make the field larger or smaller, provide a width: field 30 field 300 Fields will scroll when necessary. Larger amounts of text can be entered in an area. Areas also accept an enter key and will break lines. area You can also specify the area size: area 160x200 To force the text in an area to wrap rather than scroll horizontally, provide the wrap option: area wrap ===Text Setting To set the value of a text field under program control, use /text: e.g. across backtile polished return t1: txt 200 "This is some original text" return f1: field 200 "Some field text" return a1: area {Some original area text.} wrap 200x80 return button 200 "Change Text" [ t1/text: "Some different text" f1/text: "Some new field text" a1/text: {Some wrapping text in the^/ area field to^/ show that this^/ is supported} show [t1 f1 a1] ] ===Text Lists Text lists are easy to create. Here is an example. text-list "Eureka" "Ukiah" "Mendocino" You can also provide it as a block: text-list data ["Eureka" "Ukiah" "Mendocino"] Almost any type of block can be provided. Here is a list of all the files in your current directory: text-list data read %. Here is a list of all the words REBOL has scanned: text-list data first system/words ===Scrolling Text List A style to allow maintenance of lists from Brett Handley on the REBOL list: style updatable-text-list text-list with [ update-slider: does [ sld/redrag lc / max 1 length? head lines ] ] tl: updatable-text-list 300x100 data copy system/locale/months button 300x20 "Delete first entry on the list" [ remove tl/data tl/update-slider show tl ] button 300x20 "Append the 'now' timestamp to list" [ append tl/data mold now tl/update-slider show tl ] ===Text List Picked Values list-of-letters: text-list "a" "b" "c" "d" "e" button 200 "Pick Item 3" [ clear list-of-letters/picked append list-of-letters/picked pick list-of-letters/data 3 show list-of-letters ] ===Images By default an image will be scaled to fit within a face. image 60x60 polished image polished red Images can be framed in a number of ways: image 100x100 polished frame blue 5x5 image 100x100 polished bevel image 100x100 polished ibevel 6x6 Most other faces can accept an image as well as text: box 100x100 polished button "Button" polished purple toggle "Toggle" polished blue red field bold "This is a field." polished effect [emboss tile] field bold "This is another field." polished effect [brighten 100] The image can be provided as a filename, URL, or image data. ===Backdrops A backdrop can be a color, an effect, an image, or a combination of the three. For example a backdrop color would be written as: backdrop navy title "Color Backdrop" gold To create a backdrop effect provide it on the line: backdrop effect [gradient 1x1 0.0.100 100.0.0] title "Gradient Backdrop" gold A backdrop image can be a file, URL, or image data: backdrop polished title "Image Backdrop" red The backdrop image can be colorized: size 400x500 backdrop polished blue title "Blue Image Backdrop" The image can include an effect: backdrop polished effect [fit gradcol 1x1 100.0.0 0.0.250] title "Gradient Image Backdrop" ===Backtile To make a backdrop use a tile effect there are two options: backdrop polished effect [tile] banner "This shows a backdrop with a tile effect" or backtile polished banner "This demonstrates backtile" Note the difference between: size 400x500 backdrop polished banner "Here one image is stretched to cover the canvas" and size 400x500 backtile polished banner "Here one image is repeated to cover the canvas" ===Effect Facets A range of effects are supported for faces. All of these effects are performed directly on the face when it is rendered. Here are examples of a few possible effects in top to bottom then left to right order: style polished-steel image 80x60 polished polished-steel effect [flip 1x1] polished-steel effect [rotate 90] polished-steel effect [reflect 1x1] polished-steel effect [crop 0x50 120x60 fit] polished-steel effect [grayscale] polished-steel effect [invert] polished-steel effect [difference 200.0.0] polished-steel effect [tint 80] return polished-steel effect [contrast 50] polished-steel effect [brighten 50] polished-steel effect [sharpen] polished-steel effect [blur] polished-steel effect [colorize 204.0.0] polished-steel effect [gradcol 1x1 150.0.0 0.0.150] polished-steel effect [gradmul 0x1 0.100.0] polished-steel effect [grayscale emboss] Effects can be used in combination to create other interesting results. However, keep in mind that the computations are performed in real time. If complex combinations are required, a temporary image should be created with the to-image function. ===Actions An action can be associated with almost any face. To do so, follow the face style with a block: button "Test" [alert "test"] The block is used as the body of a function that is passed the face and the current value (if the face has one). For example: toggle "Toggle" [alert form value] rotary "A" "B" "C" [alert form value] text "Click Here" [alert face/text] If a second block is provide, it is used for the alternate actions (right key): button "Click Here" [view/new layout [txt "action"]] [view/new layout [txt "alt-action"]] Use variables to modify the contents or state of other faces. For example, the slider will update the progress bar: slider 200x16 [p1/data: value show p1] p1: progress !More action on actions needed... ===Show After the state is changed for a user interface element, it must be re-drawn to be reflected on the user interface canvas. Accomplish this with the show message. backtile polished across toggle "Toggle State" [ cybernetics?/data: not cybernetics?/data show cybernetics?] return label "Are you interested in cybernetics?" cybernetics?: check One show command can be used for multiple user interface elements backtile polished orange across b1: check label "Red" return b2: check label "Green" return button 200 "Change State But No Refresh" [b1/data: not b1/data b2/data: not b2/data] return button "Show" [show [b1 b2]] ===Hide A user interface element can also be hidden. backtile polished orange across c1: check hide-button: button "Hide" [hide c1] return show-button: button "Show" [show [c1 d2]] The show-button action tries to show a user interface element 'd2' that does not exist. REBOL/View ignores these. ===Invisible Faces To make a button invisible when the view is opened, you can define an invisible button style This approach sets the show? value to false when the user interface element is initialized. across style invisible-button button with [append init [show?: false]] late-shower: invisible-button "I'm Here" return return button 200 "Show Invisible Button" [show late-shower] This works for the other visible user interface element. ===Focus A user interface element can programmatically be given the focus. across backtile polished button 200 "Set focus to Phone Field" [focus f2] return label "Name: " f1: field 100 return label "Phone: " f2: field 100 return button 200 "Remove focus from Phone Field" [unfocus f2] return button 200 "Hide the Phone Field" [hide f2] return ---Focus Defect !Note that the tab function shows a hidden field. I have assumed that this is a defect. If a field is hidden, the tab button should not make it visible. This has been previously sent to feedback. ===Radio Buttons A radio button is used to make a choice between mutually exclusive values. Your preferred programming language is REBOL or C++ or PL/1 or APL but it is only one of those. across backtile polished radio of 'programming-language pad 0x-4 label "REBOL" return radio of 'programming-language pad 0x-4 label "C++" return radio of 'programming-language pad 0x-4 label "PL/1" return radio of 'programming-language pad 0x-4 label "APL" return To mix two groups of radio buttons on one screen, associate them with their groups using the "of 'word". In the above, the grouping is 'programming-language. across backtile polished radio of 'programming-language pad 0x-4 label "Language: REBOL" return radio of 'programming-language pad 0x-4 label "Language: C++" return radio of 'editor pad 0x-4 label "Editor: TextPad" return radio of 'editor pad 0x-4 label "Editor: Notepad" return The padding in the above is needed to keep the label aligned with the radio button. across backtile polished orange radio of 'programming-language pad 0x-4 label "REBOL" return radio of 'programming-language label "APL" return ===Radio Button Settings A radio button is not very useful unless you can find out what its setting is and change that setting under program control. across backtile polished orange rebol-radio: radio of 'programming-language [programming-language: 'rebol] pad 0x-4 label "REBOL" return apl-radio: radio of 'programming-language [programming-language: 'apl] label "APL" return button 200 "Toggle radio button" [ apl-radio/data: not rebol-radio/data: not rebol-radio/data show [rebol-radio apl-radio] ] ===Check Box ---Purpose A check box is used to allow user interface choices where the choices are not mutually exclusive. across backtile polished orange c1: check label "Likes animals" return c2: check label "Like Monkees" return c3: check label "Like The Animals" ---State A check box is not much good if you can't get and set its state (on or off). across backtile polished orange c1: check label "Likes animals" return c2: check label "Like Monkees" return button "Set State" [ c1/data: true show c1 c2/data: false show c2 ] ===Sensor ---Purpose A sensor is an invisible user interface element. Using a sensor only makes sense in a few instances. If you want a keycode action where there is no visible user interface element to link the action to then a sensor can be used. This sensor code adds an Escape or Back or Enter action that will close the window. sensor 1x1 keycode [#"^M" #" " #"^(back)" #"^(ESC)"] [unview] Or if you want to make portions of an image 'hot' instead of putting buttons on top of the image, then a sensor will achieve this. across backtile polished orange txt "Click on the upper left section of the gray image to invoke the sensor action" return animage: image 100x100 polished ; here the image is just the polished area at animage/offset sensor 50x50 [alert "You pushed over the sensor"] ===Displaying Script Values If the script has a standard format headings, including custom ones, these can be used in the application by picking them from the system/script/header. backtile polished across banner "About" return text font-size 16 rejoin ["Title: " form system/script/header/title] return text font-size 16 rejoin ["Originator: " form system/script/header/author] return text font-size 16 rejoin ["Modifier: " form system/script/header/modifier] return text font-size 16 rejoin ["Version: " form system/script/header/version] return text font-size 16 rejoin ["Updated: " form system/script/header/date] return button "OK" [unview] ===Toggle A toggle button represents boolean state - either on or off. The button stays down until toggled again. Colors and text can be paired for "on" and "off" state. toggle "Up" "Down" red blue To set the state via program control, use: across backtile polished return t1: toggle "Up" "Down" red blue return button polished 204.0.0 100 "Toggle State" [ t1/state: not t1/state show t1 ] ===Rotary Buttons Rotary buttons are a different sort of user interface device. They can cause some challenges because the state is what's showing so you have to blindly "toggle" to get to a state that you want. But for quick and easy uses where the user is familiar with the options, they can be handy. If you plan to use them for a long list of items such as shown below, they might give you some usability concerns. ---Example across backtile polished rotary data ["First" "Second" "Third"] ---Setting State across backtile polished return r1: rotary data (my-options: ["First" "Second" "Third"]) return button 200 "Change Rotary State" [ r1/data: next r1/data if tail? r1/data [r1/data: head r1/data] show r1 ] ---Example - Usability For Unfamiliar List Contents The rotary button demonstrated here contains some information unfamiliar to most (Saturn's satellites). Use it to to set the state so that "Calypso" is set. Doable but without knowing the order each re-paint has to be checked to ensure that it is not "Calypso" before clicking again. If you do click past the choice that you want, there is no back function so you have to cycle through again. return rotary data [ "Pan" "Atlas" "Prometheus" "Pandora" "Epimetheus" "Janus" "Mimas" "Enceladus" "Tethys" "Telesto" "Calypso" "Dione" "Helene" "Rhea" "Titan" "Hyperion" "Iapetus" "Phoebe" ] ===Arrows REBOL/View supports arrows as simple user interface elements. Actions can be associated with them. ---Arrowheads And Actions By default, the arrow is 20x20 across size 200x100 backtile polished at 50x50 arrow left [alert "You pressed the left arrow"] [alert "You pushed the alternate button on the left arrow"] at 70x30 arrow up at 90x50 arrow right [alert "You pressed the right arrow"] at 70x70 arrow down ---Very Sharp Arrows And with a little work the arrows and boxes can be merged to look sharper. Here is a "sharp at both ends" arrow from the block diagram script by Carl: origin 0 backcolor white at 0x0 box 40x40 white effect [arrow rotate 270] at 110x0 box 40x40 white effect [arrow rotate 90] at 24x10 box black 100x20 ---Arrow Blend So that shows you how to make an arrow blend into your background size 100x100 across backdrop gray at 50x50 box 40x40 gray effect [arrow rotate 90] at 40x67 box 25x5 black ===LED LEDs would be used to display state (on or off). Clicking the LED toggles its state and changes its color. LEDs do not support alternate mouse button actions. across banner "Light Emitting Diode" return l1: led 10x10 [alert "LED left mouse action"] label "Alert status" l2: led 10x10 [alert "LED left mouse action"] label "Network status" return button "Change state" [ l1/data: not l1/data l2/data: not l2/data show [l1 l2] ] ===Box ---Boxing Draw boxes of any heigth and width with the box style box "Large Box" 200x400 polished orange ---Boxes As Lines If you make the box narrow enough or short enough it is a line (or a dot). across size 300x300 backtile polished at 50x0 box 3x100 gold at 0x50 b1: box 100x3 gold at 10x10 box 5x5 red ---Boxes Can Grow across size 300x300 backtile polished at 150x0 b1: box 100x3 gold return pad 0x100 button "Grow Down" [ for i 3 300 1 [ b1/size/y: 1 + b1/size/y wait 00:00:00.01 show b1 ] ] return pad 0x100 button "Back Up" [ for i 300 3 -1 [ b1/size/y: b1/size/y - 1 wait 00:00:00.01 show b1 ] ] You might even find a use for it. ---Grid Effect Not sure of the use for this yet but here is what you can do: return box "Grid Lock" with [effect: [grid 20x20 8x8 4x3]] white 300x200 return box "Grid Lock" with [effect: [grid 20x20 5x5 3x3]] white - 80 300x200 ===Frame Earlier versions of REBOL VID supported frames in layouts such as view layout [frame "This is the Bay" %bay.jpg] These are no longer valid. But frames can be put around some user interface devices: image 100x100 polished frame red ===List A list is an iterated sub layout and takes a layout block that uses the Visual Interface Dialect. The styles in the layout will be repeated until there is no more room to fit them within the list dimensions. ---Why A face can be iterated to create a number of virtual faces. For instance, when displaying a list of ten buttons, each of the buttons does not need to be created as a separate object. If the buttons only differ by a few facets (such as position, text, and action taken on selection), a model face can be created and iterated for its other position. This is useful when creating scrolling lists of files and other data sets that share the same appearance. ---Supply Supply provides the data to the list for an iterated face. do [cnt: 0 list-collection: [aqua sky water] ] backtile polished orange across list-displayed: list 100x72 [ origin 0 space 0x0 across color-field: txt bold 80x24 ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [one-color] index ] return txt gold 180 "OK ... but not too useful" ---Supply Columns Maybe adding some more columns would be better. Here I'll add a column of buttons that display the color name and a column of text strings in italic. do [ cnt: 0 list-collection: [aqua sky water gold silver coffee] ] backtile polished orange across list-displayed: list 300x200 [ origin 0 space 0x0 across color-field: txt bold 80x24 color-button: button 80x24 pad 5x1 txt 100 italic ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [ [one-color] [to-string one-color] [rejoin [" " to-string one-color]] ] index ] return txt gold 300 {A bit more interesting but the last row repeats to fill the list size. Some of the other VID components will automatically stretch to fit the size needed (such as this txt field) but the list does not behave that way. You have to make the list size fit its data or make it smaller and add a vertical scroll capability. That is shown a little later on.} ===List With Supplied Data This example is to show adding action to the list and adds a horizontal line between the rows. do [ cnt: 0 list-collection: [aqua sky water gold silver coffee] ] backtile polished orange across list-displayed: list water edge [size: 6x6 color: silver] 350x96 [ origin 0 space 0x0 across color-field: txt 60 [alert rejoin ["You pressed the " face/text " text field"]] pad 45x0 color-button: button 80 [alert rejoin ["You pressed the " face/text " button"]] pad 5x0 txt 120 italic return box 350x1 white ; this causes a horizontal line to appear between each row ] supply [ if none? one-color: pick list-collection count [exit] face/text: do pick [ [one-color] [to-string one-color] [rejoin [" " to-string one-color]] ] index ] ===Supply List With Scroll This example shows a supplied list with a scroll capability. More colors are added to demonstrate scrolling. Note that this is a verbose list of code where I added comments for my understanding of how the scroll was linked to the list. The same effect can be accomplished with fewer lines of code. do [ ; first this do block creates the data definitions needed. slider-position-clicked: 0 count: 0 x: 450 y: 300 row-y: 16 ; the row height includes the data plus any separator lines list-size: to-pair reduce [x y] ; this is the size of the display list separator-size: to-pair reduce [x 1] slider-size: to-pair reduce [24 y ] list-collection: [ aqua bar-color base-color beige black blue brick brown button-color coal coffee crimson cyan forest gold gray green ivory khaki leaf linen magenta main-color maroon mint navy oldrab olive orange over-color papaya pewter pink purple rebolor red sienna silver sky snow tan teal violet water wheat white yellow ] supply-style: stylize [ button-fixed: button left coal to-pair reduce [80 row-y] ; these keep the row elements the same height text-fixed: txt to-pair reduce [160 row-y] ] data-size: length? list-collection ] backtile polished orange ; this section layouts out the list across list-position: at ; the position is captured here in order to later put the slider beside it list-displayed: list linen edge [size: 6x6 color: tan] list-size [ origin 0 space 0x0 across styles supply-style text-fixed [alert rejoin ["You pressed the " face/text " text field"]] button-fixed [alert rejoin ["You pressed the " face/text " button"]] pad 5x0 text-fixed 80 italic [alert rejoin ["You pressed the italic " face/text " text field"]] return box separator-size gray ; this causes a horizontal line to appear between each row ] supply [ count: count + slider-position-clicked if none? one-color: pick list-collection count [exit] face/text: either count > (1 + data-size) [""] [ do pick [ [one-color] ; this is supplied to the first txt field (text-fixed) [to-string one-color] ; this is supplied to the button (button-fixed) [rejoin [" " to-string one-color " "]] ; this value is supplied to the last text-fixed field ] index ] ] ; now add a slider to the side of the list at list-position + (list-size * 1x0) ; this finds the top right border of the list widget vertical-slider: slider slider-size to-integer y / row-y [ slider-position-clicked: vertical-slider/data ; the slider has to be bound to the size of the list * ((1 + data-size) - ((y / (1 + row-y)))) ; including the row height if slider-position-clicked <> count [ count: slider-position-clicked show list-displayed ] ] ===Slider A slider is interactive user interface element. The data of a slider varies from 0 to 1. backtile polished orange across slider-1: slider 200x40 return button 200 "Move first slider to 50%" [ slider-1/data: .5 show slider-1 ] return txt 200 "The second slider in this example is initialized to the 80% mark." return slider 200x40 with [append init [data: .8]] ===Progress Indicator The progress-1 face in this example is a progress indicator. Because it is only displaying information, it is non-interactive i.e. you can not change its value by dragging its edges. The alternate button is not supported on a progress indicator. backtile polished orange across slider 200x40 [ progress-1/data: value field-1/text: join (to-integer (100 * value)) " %" show [progress-1 field-1] ] return progress-1: progress return field-1: field ===Panels Panels are used to create sub-panes that can be more easily managed by grouping the user interface devices on a panel. The first example below shows how to use panels for layout alignment. By creating a panel definition, all of the components defined within it are aligned relative to its origin. across backtile polished brick tabs 50 return panel-1: panel 250x120 [ backtile polished across return button water 200 "Button A" return button aqua 200 "Button B" return button sky 200 "Button C" ] at panel-1/offset + panel-1/size panel 60x90 [ ; start at the bottom right corner of panel-1 backtile polished across return button tan 20 "1" return button coffee 20 "2" ] ---Multiple SubPanels example This example from the REBOL html documentation shows how to easily hide and show sections of a user interface by displaying them on the face area of a box. do [ ; define two panels panel1: layout [ origin 8x8 h2 "Panel 1" field "Field 1" field "Field 2" button "The Answer" [alert "I know nothing."] ] panel2: layout [ origin 8x8 h2 "Panel 2" across txt "X:" slider 150x16 return txt "Y:" slider 150x16 return check [panel2/color: maroon show panel2] txt "Don't click this" return check [panel2/color: silver show panel2] txt "Click this" return ] panel1/offset: 0x0 panel2/offset: 0x0 ] vh2 "Subpanel Examples" ; now demonstrate panel use guide pad 20 button "Panel 1" [panels/pane: panel1 show panels] button "Panel 2" [panels/pane: panel2 show panels] button "Quit" [unview] return box 2x140 maroon return panels: box 220x140 do [panels/pane: panel1] ===Simple Default Style Override The style's default look can be overriden easily with one line of code. For example, to make the default button size 200x200 with a water color, use style button button 200x200 water button "Big Blue Button" [unview] To make the toggle some different default colors: style toggle toggle crimson sky toggle "Up" "Down" Note that these stay in effect until they are overridden so if you use the default values, exercise some care unless you meant to do that. ===Image Maker An option used by Carl in some of his programs is to let View create specific icons so that you have portability and more control of look of the image then if you referenced an external file such as gif that was a bullet display. Here's how to do that: do [ make-image: func [xy wh eff] [ eff: layout [ size 20x20 at xy box wh effect eff ] eff/color: rebolor to-image eff ] dot: make-image 6x5 9x9 [gradient 1x1 255.0.0 0.0.0 oval key 0.0.0] dot-big: make-image 8x7 12x12 [gradient 1x1 255.0.0 0.0.0 oval key 0.0.0] arr: make-image 3x3 14x14 [arrow 0.0.127 rotate 90] ard: make-image 3x3 14x14 [arrow 0.0.127 rotate 180] ] ; end of "do" - it is needed here because easyvid approach is expecting vid dialect commands banner "Presentation Points" size 400x300 across style label label gold ; make a label's text be a different color than the default return image dot label "This is bullet point number 1" return image dot label "This is bullet point number 2" return image arr label "This is arrow point number 1" return image ard label "This is an arrow making a different point" return image dot-big pad 0x4 area 300x80 wrap "And because these arrows and dots are images, action can be added to them to make them 'hot' with mouse actions including 'over'." ===Needs Some Work !More to come.

This is a slightly modified version. Here again a DO block precedes the layout code for non-layout initiatiation ... here the definition of a function. Why make a diagram this way? 1. One reason is that it can be interactive ... the sections are all "hot" with a few lines of code. Here they pop up REBOL Dialogs but they could do anything that can be coded even something as simple as launching a browser on a different URL for each diagram component. The "Compositor" box demonstrates this by launching your browser on the REBOL.com site. 2.

Assumes you have set up your email in set-user e: field "Email" s: field "Subject" m: area "Body" btn "Send"[send/subject to-email e/text m/text s/text alert "ok"] * better yet, make your own... if the code for the basic is 1 line, then a custom version is not far away. Here's an example that allows selection of your frequent contacts (entered in the names-addresses series) and keeps a journal of email that you have sent (using this code) in file email-journal.txt. Assumes you have setup your user profile correctly to allow sending of email. do [ names-addresses: [ "Contact 1" [contact1-:-no-such-address-:-com] "Contact 2" [contact2-:-no-such-address-:-com] "Contact 3" [contact3-:-no-such-address-:-com] ] names: copy [] foreach [name address] names-addresses [append names name] journal?: false ; set to true if want to journalize sent email ] e: rotary 200 data sort names s: field "Subject" m: area 500x400 wrap "Body" btn "Send"[ send/subject who-to: select names-addresses e/text m/text s/text alert join "Sent email to: " form who-to if journal?

It has been wrapped in a DO block so it does not send errors to the console. ---Quick Send Short Message do [ send [address-:-isp-:-com] "My Message" ] ---Send Longer Message Now a more complex message where there is a body to the message: do [ send [address-:-isp-:-com] {Sample Message This is the body of the message } ] ---Send with One Attachment Here, so that the sample does not fail, test file(s) are created by the code before attempting the send. do [ test-file: %file-attachment.txt write test-file {Just some test data to create a file} send/attach [address-:-isp-:-com] {Sample Message This is the body of the message } test-file ] ---Send with Attachments And a message with multiple attachments. Here, so that the sample does not fail, test file(s) are created by the code before attempting the send. do [ files: [%file-attachment.txt %second-attachment.txt] foreach file files [write file {Just some test data to create a file}] send/attach [address-:-isp-:-com] {Sample Message This is the body of the message } files ] ---Send to Multiple Addresses Here, so that the sample does not fail, test file(s) are created by the code before attempting the send. do [ files: [%file-attachment.txt %second-attachment.txt] foreach file files [write file {Just some test data to create a file}] send/attach [[address-:-isp-:-com][asecondAddress-:-isp-:-com]] {Sample Message This is the body of the message } files ] ---Send/only Same send only just provide the SMTP server with one copy: Here, so that the sample does not fail, test file(s) are created by the code before attempting the send. do [ files: [%file-attachment.txt %second-attachment.txt] foreach file files [write file {Just some test data to create a file}] send/only/attach [[address-:-isp-:-com][asecondAddress-:-isp-:-com]] {Sample Message This is the body of the message } files ] ---Send With Header This example uses a Do block to wrap the code.

Geomol: 17-Jan-2005	@Ashley 1) a <title> option for =table. Yes, I considered this. HTML has a caption option for tables and optional align (top\|bottom). If align isn't there, it's up to the browser to deside. I found it a bit confusing, and by putting the title of the table yourself at the place, you want, you get the result as expected. 2) a right option for =image. Yes, good idea. I've also considered the situation, where text should go around images. But I haven't found a good way to specify that yet. 3) Is "/" needed in state off tags? Yes, I think so, because it's easier to understand, if you have e.g. several bolds after each other. Example: This is some [b]text[/b], where there are [b]several examples [/b]of[b] bold[/b] words. is easier to understand than: This is some [b]text[b], where there are [b]several examples [b]of[b] bold[b] words. Also if you make a style, that is bold, then you wan't to use [/b] to undo bold. Would be confusing, if you used [b] for that too.

Chris: 3-Feb-2005	.footer {width: 50%; float: right; text-align: right;} .processingtime {width: 50%;} Should be enough on the face of it. Adding margins or padding will need a little recalculation...

Ashley: 15-Aug-2005	Latest build available at: http://www.dobeash.com/files/RebGUI-033.zip * Unzip this file into your existing RebGUI 0.3.0 distribution. Requires View 1.3.1 * Minor synchronization release to align with latest REBOL/View 1.3.1 builds and documentation. I've also removed all SVG related code until such time as AGG fixes allow SVG Renderer project to complete.
BrianW: 26-Aug-2005	How do I right-align the text in a field?
Henrik: 26-Aug-2005	field font [align: 'right] should work
Robert: 22-Apr-2006	How can I create something like a STYLE to avoid always having to specify things like font [align: 'right]
Anton: 22-Apr-2006	view layout [style my-field field font [align: 'right] my-field my-field]
Anton: 22-Apr-2006	or you could restyle the field with layout [style field field font [align: 'right] field field]
Anton: 22-Apr-2006	But I suppose you could do something like: rebgui-widgets: make rebgui-widgets [ my-widget: make one-of-the-widgets [font: make font [align: 'right]] ]
Robert: 21-May-2006	I just want to inform you what enhancements I needed and Cyphre did so far for RebGUI: table: Add an API to table that allows to change the columns layout at runtime: my-table/set-columns ["Column 1" left 0.25 "Column2" center 0.75] drop-list: fire action only if selection was made/changed, at the moment action fires if clicked on field too general: on-un/focus should be fired if user clicks an other widget, not only if carets leaves the widget when TAB is pressed table: moving bar up/down with keyboard should fire click-action, alternativ: pressing RETURN can fire click action table: align header text like data (left, center, right) at the moment always left table: TRAC #21 TRAC #5 Cyphre: should be fixed but please test it and let me know. TRAC #6
Robert: 18-Jun-2006	ATTENTION: rebgui-edit.r was not yet merged. Latest revision doesn't include older changes. We will do this ASAP. But rebgui-edit.r is required in this version otherwise all other changes done by us might not work. FIXED rebgui/pad: Now only works for horizontal padding. Padding should happen depending on the layout direction left-to-right or top-to-down. Cyphre: now PAD works according to the AFTER settigns. Example: display "Test" [ after 3 field pad 5 field pad 5 field pad 5 field pad 5 field pad 5 field ] Robert,let me know if it works like you wanted. FIXED group-box: When setting a new title group-box/text: "new-title" the surounding frame needs to be adjusted to the new text-width. FIXED drop-tree: When selecting different quick-access buttons directly one after the other, the drop-tree shouldn't close FIXED drop-tree: Highlighting the pressed quick-access button with green, the hovered one as is in orange. To give user visial feedback. FIXED general: a way to sepcify "align ['left]" for all further widgets to avoide repeation. Idea: Add disaply keywords: left, right, center Cyphre: added keyword TEXT-ALIGN left/right/center. Example: display "Test" [ text-align right after 3 t: text 20 "test 1" field "test 2" field "test 3" text-align left field "test 4" field "test 5" field "test 6" ] FIXED drop-list: an option that will show the list layered above everything (like the tree list of drop-tree). Cyphre: added drop-list/popup-mode: 'inside(default) or 'outside note: the same works for drop-tree FIXED drop-tree: changing state of the drop-tree (a new entry was selected) should only be done if the ACTION code returns TRUE. Otherwise the old state is kept, the drop-tree is closed and nothing happens. This allows the code to check for some pre-conditions before changing the state, and give some feedback to the user. Much like the on-unfocus functionality of RebGUI. FIXED drop-tree: pressing the quick-access numbers doesn't work any more as the drop-tree closes now if the mouse is clicked outside the drop-tree FIXED table: table/selected returns NONE if the table is empty and no record is selected. If there was one recrod selected at any time, than table/selected returns [none none <repeated for number of columns>]. If not row is selected at any time, table/selected should just return NONE. FIXED table: If a table is re-used in that the table is reused with code like: insert clear table/data [...] people/redraw and there was a row selected before, than the internal state is still in "row selected" but the new row isn't highlighted. Here internal state and GUI don't match. FIXED drop-tree: clicking a "+/-" in the tree only open/closes the tree without calling the action for the node FIXED drop-tree: Re-add whole line selection and hovering functionality (so that mouse does not have to be over text) FIXED drop-tree: Add an option to get big fast-selction keys aligned left-to-right Cyphre: added drop-tree/expander-mode: 'big(default) or 'small FIXED button: Add an option to disable a button my-button/active: true/false, if disabled the button is drawn greyed-out Cyphre: usage is my-button/active: true/false show my-button FIXED field: Support number datatypes for TEXT so that things like field-a/text + field-b/text can be used Cyphre: you need to set field/edit-mode: 'numbers to activate this behaviour for field(othervise it works like a normal field) 2nd implementation uses own styel: number-field FIXED radio-group: Add an API that allows to provide a new DATA specification block at runtime or a way to alter the text of the radio fields at runtime. Cyphre: now you can just change the data content and do show on the radio-group like: my-radio-group/data: ["item1" "item2" "item3" "item4"] show my-radio-group Note that it won't react on change of number of items. Just change of texts. FIXED radio-group: Add a way to select one radio field at run-time added accesor select-item item [integer!] usage: my-radio-group/select-item 2 show my-radio-group note: you can get the selected item using my-radio-group/picked, you can get the text of selected item using my-radio-group/selected FIXED drop-tree/grey-out: Can it be done in that we only show the text in a light grey instead of black? Like Windows does it. Cyphre: now the masked text is light grey FIXED on-focus / on-unfocus: If FALSE is return from the ACTION and the user clicked somewhere on the screen, the focus is still in the "field" but no cursor bar is visible FIXED drop-list: IIRC in your widgets it was possible to start typing and the selection list was filtered. A mandatory feature for the drop-list :-)) Cyphre: added drop-list/editable? flag to enable/disable editing of the drop-list field also added drop-list/auto-fill? flag which enables automatic text filterin from the selection list FIXED general: add hover tooltip help option to every widget (global patch) Cyphre: added TOOL-TIP facet to rebface object. If TOOL-TIP is set to string! value a tooltip is shown when mouseover such widget. example: display "test" [ button "press me" tool-tip "press this button to continue" ] FIXEDdrop-list: proivde a much better selection-list opening algorithm especially for long lists. Open upward, downward, middle like so that as much entries are shown for the given screen space. And an option that will show the list layered above everything (like the tree list of drop-tree). Cyphre: -added droplist/lines - can be 'auto (default) or integer! to force number of shown lines in droplist -added droplist/droplist-mode - can be 'auto (default) 'upward, 'downward or 'middle to force way how the list is popped up you can use various combination of those settings. FIXEDtable: Add an API that allows to select a row at run-time. Cyphre: Usage is for example: my-table/select-row 5 show my-table FIXEDtable: Add an API to table that allows to change the columns layout at runtime: my-table/reset ["Column 1" left 0.25 "Column2" center 0.75] Cyphre: I added the functionality byt the API call is my-table/set-columns ["Column 1" left 0.25 "Column2" center 0.75] FIXEDdrop-list: fire action only if selection was made/changed, at the moment action fires if clicked on field too FIXEDgeneral: on-un/focus should be fired if user clicks an other widget, not only if carets leaves the widget when TAB is pressed FIXEDtable: moving bar up/down with keyboard should fire click-action, alternativ: pressing RETURN can fire click action FIXEDtable: align header text like data (left, center, right) at the moment always left FIXEDtable: TRAC #21 FiXEDTRAC #5 Cyphre: should be fixed but please test it and let me know. FIXED*TRAC #6
Robert: 17-Nov-2006	Ashley, please take a look at the xpeers RebGUI stuff. We have added a lot and should align the code lines.
Robert: 3-Apr-2007	BTW: Can we somehow align while you do RebGUI 2? I want to follow the new release and provide our code to it as well.
Ashley: 3-Apr-2007	you will find it in the RebGUI directory on xpeers ... got it the first time, just making sure I was looking at the most current version. FYI, tooltips had me baffled for a long time (they worked for you, consumed tons of CPU for me) until I realized they were only a problem with the new tab-panel implementation ... which now stores all tabs in a pane and uses the show? attribute to work out which one is visible or not (the original stored hidden tabs in a data block). The fix was simple, change the tooltip code to ignore faces with show?: false. strip tree widget from drop-tree ... the tree widget I'm working on is similar to text-list but with leading triangles (indented by level) that toggle between sideways (close leaf) and down (open leaf). Not sure whether Cyphre's one is based on the same [simple] concept. Can we somehow align while you do RebGUI 2? ... as discussed previously (see post from 10-Mar), with the key points being: 1) Use (and possible extension) of global UI settings (colors, sizes, effects, behaviors) in %rebgui-ctx.r 2) Widgets should define a 'rebind func if they need to change a statically bound UI setting (e.g. color) 3) Use the new tab-panel widget and a fourth: 4) Layout uses 'tip (not 'tooltip) to specify the widget's tip string! Note that the current build has had most widget-specific exceptions removed, especially from %rebgui-edit.r; and that /dialog (hence popup) code has been rewritten to support true modal dialogs (that can in turn call additional modal dialogs). The later improvements are courtesy of recent REBOL/VIew popup changes.
Ashley: 16-Apr-2007	How curious, I've just discovered that hilight-on-focus doesn't work with align: right. Need to fix this (for spinner).
Graham: 20-Apr-2007	If you have a large left box, how do you then align the following widgets so that 'return aligns to the left large widget? In VID you set a ruler thingy ...
Graham: 20-Apr-2007	I had a calendar widget1 return widget2 and I wanted widget2 to align with the right border of the calendar so now I have calendar panel blue data [ widget1 return widget2 ]
Graham: 22-Dec-2008	I've got three vertically left aligned group-box's and I'm sizing them the same by using absolute sizes to also right align them. But this means I can't use different gui sizes because then the contents of the boxes can exceed the group-box. But if I use automatic sizing using -1x-1, then I can't get both left and right sides of the group-boxes to align ... or can I??
marek: 3-Aug-2009	>> display "" [b1: button 5 "Short" b2: button 5 "Very Very long" button [print [b1/size b2/size]]] 42x20 93x20 Is this as intended? One more disadventage is no multiples of 4; hard to align your widgets.
Ashley: 14-Aug-2009	Pekr, above issues noted. Tooltips are being added back to toolbar [only] as they were in the early builds. I'm also looking at ways of reducing memory usage (sharing more objects in layout and pre-building certain common font usage cases (e.g. align: 'center)).

Awi: 23-Aug-2011	I found the bug, it's in the rebgui-widgets.r -> face-iterator font: either 'left = aligns/:i [default-font] [make default-font [align: aligns/:i]] should be replaced with font: either 'left = aligns/:i [make default-font []] [make default-font [align: aligns/:i]] otherwise, selecting a line will change default-font/color to white, thus any widgets using default-font shown thereafter will appear blank

btiffin: 9-Oct-2007	Post(s) that follow are the R3 Alpha version of the format function prepped for R2; at this stage, it could probably be called pad or align. I've split the header from the function.

Pekr: 27-Nov-2008	Why there is another style needed, to properly align elements? Why isn't panel and group enough?
Pekr: 27-Nov-2008	I don't understand how group and panel could be usefull, if it can't precisely align elements? Why not use container all the time then?
Henrik: 27-Nov-2008	it does precisely align them, but the draw block is not suitable for that.
james_nak: 3-Dec-2008	One of our .net programmers showed me something kinda cool yesterday. They were "child" windows of a main window that would align together if you brought one within a certain proximity to the other. From that point the top bar from either window moves both. Of course it's not as cool as having draggable screens like we did in '86 but...
Maxim: 29-Apr-2009	if we align to first item of the block, then what would be the third, will become something else, when you hit the head of the series.... this adds a lot of complexity to the loop for nothing I think.

BrianH: 17-Dec-2008	The presenter chat interface is too tall to fit on a 1024x768 screen, let alone the 1024x600 on my netbook. It would help if you got rid of <tr> <td align="center"> </td> </tr> that is above the row where the flash is embedded, or better yet replace the whole table with a <div style="text-align: center">...</div> However, even when you reference the the flash itself, it has some kind of title at the top that pushes the interface down so far that you can't see the text entry field on a 1024x768 screen. This is a bug in the flash.

Dockimbel: 4-Sep-2008	I also need to add extend Draw dialect with a new command: text-box. It's an improved version of 'text that allow you to define a bouding box, align the text horizontally and vertically and auto-wrap text.
Henrik: 4-Sep-2008	DocKimbel, you'll find that R2 Draw has kerning problems. Or at least that's what it had the last time I looked. That makes it difficult to center and right align text. This is not an issue in R3.
Dockimbel: 16-Sep-2008	I found a justification routine (doing also alignement). I need to study it to see if it fit my needs : align and line-wrap at the same time.

Maxim: 16-Sep-2009	no objects in extensions... I was just thinking yesterday that a struct type in R3 could be a good idea now that we have extensions. Carl could wrap it up quickly since structs only store and align data, no rebol code. but I think I'll build a struct <-> block set of tools in C and REBOL for extensions in the meantime... this will be handy for sure.

Maxim: 12-Aug-2010	it should be a switch, since you want your coordinates to align. if you have to add graphics to text, for example, they should use the same coordinate system.
Pekr: 24-Jan-2011	How is now R2's face/pane, and earlier face/faces replaced? I can't see it in the structure. Is that a gob!? >> help main-pan MAIN-PAN is an object of value: style word! vpanel facets object! [init-size min-size max-size align valign res... state object! [mode over value] gob gob! offset: 3x46 size: 572x503 options object! [content] tags map! make map! [ panel true ] draw-result block! length: 45 intern none! none name word! main-pan names object! [t1] I really miss the simple aproach of R2 guys. I wish I had a /pane, a simple block of stored subelements, accessible via normal rebol series functions, so no need for me to investigate the special purpose functions. That's what I call simplicity.
Maxim: 27-Jan-2011	when I say static size in GLass, it just means that it doesn't fill the space. things still align and stack up automatically within the frame.
Maxim: 2-Feb-2011	I agree that precise use of the baseline should be doable. its the only way to properly handle multi-font display. it would also be nice to be able to inspect the font so that we can measure the different metrics of a font. x-height, descent, ascent, cap height, linegap (leading), H space width, etc. On the Amiga, I used to align text with these values in code and it seemed to be much better.
Pekr: 4-Feb-2011	I still miss simple style to group things. I always wanted a panel, with border, gradient, etc., but then also exactly the same style, but with zero visuals ... IIRC, in Carl's GUI, it was panel vs group - except the fact, that it group used opposite coordinate system - very unwise btw In RMA's GUI, if I am not mistaken, group is internally completly different - it is here for those users, used to VID2 - you have to use RETURN keyword, it does not align in grid cells, etc. So - how do I easily define inline style, which removes panel visuals? I don't want to create new style for such a simple and usefull thing. And I start to think, that 'group style is here just to confuse users ...
Pekr: 17-Feb-2011	I would also like style 'options block handling formalized, moving it to the style level too. We have on-* actors there. The more stuff we move there, the better. That way it will be easier to build the visual IDE tool imo .... I am talking about the following code, hopefully it is that: append panel/facets reduce/no-set switch layout-type [ panel [ [ break-after: any [ all [ in panel/facets 'break-after panel/facets/break-after ] 0 ] pane-align: any [ all [in panel/facets 'pane-align panel/facets/pane-align] 'left ]
Pekr: 4-Mar-2011	Any new timeframe of the new release? Was very busy, so no work on porting demo done on my side. Just trying to align the timeframe for next week ....
Pekr: 7-Mar-2011	I have a question towards the aproach to design a form. Following code does not work for me (result-wise): view [hpanel 2 [label "Name:" field button "ok"]] Simply put - button is on a new row, but it probably causes field to align to the right? Or more precisely - button extends the column cell, and so the field is pushed to the right in an undesirable (albeit expected) manner. Should I put buttons supporing the form out from the panel containing fields?
Pekr: 7-Mar-2011	But my above example is some food for thoughts. When I think of forms, I know that form might be enclosed in some pane (being it group or panel or frame I don't care - just visually separated from the background). Then it usually contains pairs of labels and fields. Btw - in R2 it was easy to right-align label - is that possible with R3 GUI? And I think that some buttons belong to the form - e.g. Edit, Submit, Cancel, and some might belong to the Window.
Rebolek: 7-Mar-2011	Yes, there's support for alignment. I'm not how much of it is currently accessible, but you should be able to align cells in panel.
Henrik: 7-Mar-2011	you wouldn't be able to align labels and fields correctly below eachother, as far as I can see
Pekr: 7-Mar-2011	What's the r3 equivalent to align to the right? :-)
Henrik: 7-Mar-2011	In R3 you would have several possibilites, depending on whether you want to align the label text or the label itself.
Ladislav: 7-Mar-2011	I guess, that what Pekr wants is just to be able to align the label text to the right
Ladislav: 8-Mar-2011	To Pekr - here is a layout you might not know how to lay out: stylize [lab: label [align: 'right]] view/options [ hpanel 2 [ lab "name: " field lab "last name: " field ] hpanel [button button button] ][break-after: 1]
Ladislav: 8-Mar-2011	correction: stylize [lab: label [facets: [align: 'right]]] view [ hpanel 2 [ lab "name: " field lab "last name: " field ] hpanel [button button button] ]
Cyphre: 8-Mar-2011	label-right: [align: 'right] view [ hpanel 2 [ label "name: " options label-right field label "last name: " options label-right field ] hpanel [button button button] ]
Cyphre: 8-Mar-2011	cascading styles: I meant you could write for example: stylize [ #my-panel label [ facets: [ align: 'right ] ] ] view [ my-panel: hpanel 2 [ label "name: "field label "last name: "field ] hpanel [button button button] ]
Pekr: 11-Mar-2011	Align examples - I don't understand the align+halign at all. Why the vertical coordinates of red and blue boxes are reversed?
Pekr: 11-Mar-2011	Also - please use halign instead of allignt, to be consistent with hpanel, vpanel, etc. It has imo no sense to name one property valign, and the other one align.
Rebolek: 12-Mar-2011	ALIGN, VALIGN - this is same naming as in HTML, so you can expect most people be familiar with it.
Pekr: 12-Mar-2011	as for alignment - from html I do remember align="left \| right \| center" .....
Pekr: 12-Mar-2011	alignemnt - really - go to example #35, write down all variants on paper, forget the visual representation you are provided with, and just draw it on the paper out from your head. I bet you will make a mistake. And align + valign is not understandable for me at all ....
Pekr: 12-Mar-2011	Ladislav - box model/frame is not much of an issue for me. I think that worse problem for me is how currently resizing is behaving in above mentioned styles, and all that align examples and its naming - very confusing.
Rebolek: 12-Mar-2011	align and valign are pretty standard names if you've ever seen HTML, what's so confusing about them?
Ladislav: 12-Mar-2011	#[[Pekr And align + valign is not understandable for me at all .... Pekr]] - right you are, you should see the code to understand what the text means. In short, it means, that the HALIGN and VALIGN properties are set somehow, instead of using the default values, that are 'LEFT + 'TOP

Cyphre: 21-Oct-2010	Pekr, thanks for your useful feedback, some reactions: PAGE margin should allow to set 4 sides - this is done by using ORIGIN and MARGIN pair!s in the proposal, I agree, we can use MARGIN with two pairs instead of that origin should replace scroll - ok, makes sense if we accept the point above PARA indent - INDENT should define rectangular space at the beginning of the paragraph, the left right orientation would be chosen according to the horizontal align settings in each paragraph. The value for indent could be pair! (to define the space in both ways) or number! to define just the horizontal indentation for the first paragraph line only. spacing - here I'd use SPACING [pair!] for additional space between chars (X axis) and lines (Y axis). For space around paragraph (top, left, bottom, right) I would use PADDING. paging - IMO linking of text between gobs at the C level would bring us lot of complexity. I still think we should provide functionality that can be useful at REBOL script level to handle the linkage. runaround - this needs to be well thought so it is flexible enough once we allow to use embedded gobs in the text flow alignment - I'd leave it as in the current proposal for now. Which means horizontal align can be set per paragraph vertical alignment per 'page'(=GOB) I'll be updating the current document soon to reflect all the changes from yours and other useful suggestions. I'll post here once new version is online.
