[!RebGUI] A lightweight alternative to VID

Ashley 1-Apr-2006 [3236x2] | Robert: 1) global words: they are not. Try the following: f: has [v] [display "Test" [v: field button [unview halt]] do-events] My normal approach is to wrap each display in its own function with something like: display-account-summary: make function! [id [integer!] /local f1 f2 f3 f4 f5 f6] [ ... display "Account" [ f1: field f2: field ... ] ... ] 2) tab-panel: works, just take a look at how it is used in %tour.r. Note that it defaults to "size: -1x-1". Maybe you need to make the panel contents bigger? |
face/picked: try adding a "print mold face/picked" to the table action so you can see what block value(s) are being selected. Perhaps, in a particular case, it is returning an empty block? | |
Graham 1-Apr-2006 [3238x2] | Does image still only take a filename and not an image type? |
I'm looking at capturing images from a web cam and inserting them into my program. | |
Ashley 1-Apr-2006 [3240] | The following works: a: load my-image.png display "Test" compose [image (a)] |
Graham 1-Apr-2006 [3241] | Ahh .. forgot needed to compose. |
Thør 2-Apr-2006 [3242x6] | Sorry for the proliferation of my dots, I'm forcing a resync and I'm being disconnected at about 25%... :-( |

Graham 2-Apr-2006 [3248] | Have you considered broadband ? |
Robert 2-Apr-2006 [3249] | Ashley: Do you use several display functions in your apps? At the moment I have one. I use tab-panels a lot. Hence I have one big display function. |
Ashley 2-Apr-2006 [3250] | Have about half a dozen, and I make use of 'unview-keep to only have 2 or 3 open at the same time (also useful when multiple data entry screens are open at the same time and the user clicks "commit" ... data is saved and all windows except the Main Menu are closed). |
Robert 2-Apr-2006 [3251x2] | Ok, I think I have to make some tests. |
Next one: What's the best way to create "user-selection-dependent-layouts"? For example the User select one entry in a drop-down box and depending on the value, a different layout should be shown below the drop-list. | |
Anton 2-Apr-2006 [3253x2] | Hmm.. you can do it many ways. What's the application to do and what will the window layout have in it ? |
Oh... probably you would use tab-panel. | |
Robert 2-Apr-2006 [3255] | Yes, it's in a tab-panel and depending on the selection of one drop-list the data-input form that follows the drop-list has to display different labes & fields. |
Anton 2-Apr-2006 [3256x3] | How many entries has the drop-list ? Because if it's small I might suggest using another tab-panel. Otherwise I would try to create the layout for each selection before the window is displayed. |
Or, if most of the time the labels and fields are common, but with some differences, I might use the drop-list action to hide all and show only those fields which go with the current selection. | |
ie. all the fields are placed in the same panel :) | |
Robert 2-Apr-2006 [3259x2] | Tab panels can't be used, because it's XOR. So either show A or B. |
Doing a hidden layout and than plugging it into the current one would be best. But than I have to deal with PANE etc. IMO that's to low-level. I would like to have a way to alter the layout dynamically. | |
Normand 2-Apr-2006 [3261x2] | Ashley, thanks for the answers. I cant figure out from the tour how to show some new values of data in a table. What is wrong with the instructions in the two buttons. |
Rebol [] #include %rebgui.r unless value? 'ctx-rebgui [do %rebgui.r] display "ProspectGUI" compose/deep/only [ ex-table: table 120x40 #HW options ["ID" left .2 "Nom" left .4 "Prenom" left .4] data [1 "Vac" "Gus"] [] button "Delete1" [ ex-table/data: [2 "Cah" "Sug"] ex-table/redraw ] button "Delete2" [ show-data ex-table [2 "Cah" "Sug"] ex-table/redraw show ex-table] ] do-events | |
Graham 3-Apr-2006 [3263x3] | try working with the existing data, and not creating new lists. |
insert head clear ex-table/data [2 "Cah" "Sug"] ex-table/redraw | |
when I was tabbing .. got this ** Script Error: Cannot use path on none! value ** Where: next-field ** Near: all [ item: find face/parent-face/pane face while [ if tail? item: next item [item: head item] ... | |
Robert 3-Apr-2006 [3266x2] | Ashley, what's the state for the load/save OPTION implementation into RebGUI? Did you start already? If not, let me know. That's something I want to push forward. |
load/save: I mean get back/fill in all fields in a structured way so that it can be used with SQLite. | |
Graham 3-Apr-2006 [3268] | what do you mean by this? |
Robert 3-Apr-2006 [3269] | If you have a form with several fields I want to have something like: store data-form and get back a block like this: [name text "Graham" rebol value true ...] So for all widgets where the SAVE flag is set, the name of the widgit word, the word and value is returned. With this it's possible to handle records very comfortable. |
Ashley 3-Apr-2006 [3270] | put-form/all my-display block-of-values-returned-by-sql-call blk: get-form my-display I've got as far as thinking about how it could / should be implemented (there are some interesting issues with grouping widgets like group-box, table, text-list, etc); but my focus at the moment is to complete the SVN setup / structure / documentation / usage instructions so as collaborative development can begin (and I am no longer the bottle-neck in changes being implemented). Unfortunately, I'm two weeks into an intensive four week certification course (non-IT related) so REBOL things are on the back burner for a while (although I'm popping in here to answer the odd question here and there where I can). |
Graham 3-Apr-2006 [3271] | I'm not sure that this is relevant, but I did some basic screen validation for vid, and documented here http://en.wikibooks.org/wiki/REBOL_Programming/Language_Features/Parse/Screen_Validation |
Thør 4-Apr-2006 [3272] | manual resync... |
Graham 4-Apr-2006 [3273x3] | Is there a "fit" for images as in Vid? |
umm... the other way round... display an image in it's native size. | |
unscaled. | |
Ashley 4-Apr-2006 [3276] | image effect 'fit image effect [fit] |
Julia 4-Apr-2006 [3277] | i can't undestand - what's the best way to change view of widgets, for example i want to change arraws of slider in textarea? |
Graham 4-Apr-2006 [3278x2] | this is rebgui ... |
image effect 'aspect ... was what I was looking for. | |
Julia 4-Apr-2006 [3280] | ? |
Ashley 5-Apr-2006 [3281] | want to change arraws of slider in textarea? ... change in what way? Look? Feel? Where the arrows are located? Arrows or chevrons? Colour? |
Anton 5-Apr-2006 [3282x4] | I think Julia wants to do skinning, changing the look of the slider. Well, I programmed the slider/scroller, and I can say that it is not easy to reskin. You will have to get your hands dirty :) When rebgui first came out, it was intended to be very lightweight, so I think Ashley only started to want to add fancier abilities like skinning later. When I wrote slider/scroller, I was trying to be as minimalist as possible, so it's quite "hard-wired" with respect to how it draws itself. |
Maybe Julia means how to change the colours ? Well, as I remember, I just used button colours. | |
Ashley, how's the splitting of widgets into separate files going ? What method are you using to integrate them into the final context ? | |
Here is a very simple patch to slider, which makes a nice half-second pause at the beginning of a scroll: if find [down time] act [ if act = 'down [face/rate: 2] if act = 'time [face/rate: 16] | |
