Layout

 [1/14] from: obiwanbuz::yahoo at: 20-Sep-2002 20:56


Hello, I recently started with REBOL, and I try to use defined layout into layout. I read from the VID documentation that it is possible, unless I miss-understood. Please if any body can help I would be very happy. cheers Bertrand

Hi Bertrand, I think this how-to would be the best answer to your question... http://www.rebol.com/how-to/subpanels.html If it's not what you're after, do ask again - you'll most certainly get an answer. This is a very helpful list. There's also "real" panels. Meaning, VID has a 'panel word, but I know of no description of how it should be used. Yes, that's a question for this very helpful list.

Hello, please forget that question, I found the answer in the How-to document. Cheers ----- Original Message ----- From: "B-E-P" <[obiwanbuz--yahoo--fr]> To: <[rebol-list--rebol--com]> Sent: Friday, September 20, 2002 8:56 PM Subject: [REBOL] Layout

Thanks for your answer Carl, I had a look to http://www.rebol.com/how-to/subpanels.html but it's only a part of my answer. In fact I want to dynamically add a text followed by a box to a panel for each new entry to a Personal Information Manager. I was thinking that I could define a layout with these faces, and insert it to my main panel. Maybe there is a different way to do it, I don't know. so please au-secours!!! :-) Bertrand Pivaty

Hi, Bertrand, I am not sure that I know exactly what you are looking for, but maybe it is somewhere in this example. data: ["Scott" "123 Main" "Carl" "456 Maple" "Bertrand" "789 Oak"] lo-func: func [] [ layout [ origin 0x0 text data/1 area data/2 ] ] lo: layout [ origin 10x10 b: box 200x200 button "Previous" [ if not head? data [ data: skip data -2 b/pane: lo-func show b ] ] button "Next" [ if not tail? data: skip data 2 [ b/pane: lo-func show b ] ] do [b/pane: lo-func] ] view lo --Scott Jones

First of all I want to congratulate this list as it works very well. I had a look to Graham Chiu about radio button, and his answer and Scott are very close to what I am looking for. Scott I am happy with your answer, as I learnt more about View, but I don't want to see items replacing the previous one, I would like it to be added as a suplementary face into a layout. To be more precise, say I want to implement an outliner, (you know like the one in microsoft word), if I want to insert a sub-item, it has to be displayed below its parent and shiftted to right. That' s the point. Cheers Bertrand

I wrote an article on Rebolfrance about dynamically creating a layout. You could use it too, as I know you're a french guy, too.

Thanks Philippe, it is a good article, this is more or less the the way I tried to fix my problem. But it is still not what I whant. May be I should ask the following question: Is it possible to add new face into a layout which is already displayed ? The following lines (from Philippe Oehler) is a good example of dynamically generating layout in one go, but it is done before the block is actually transformed as a layout. I want to do it after the block is drawn on the screen. Is it possible ? rebol [] fen: [backdrop 212.212.212] for e 1 10 1 [append fen reduce compose/deep ['button (join "Hello " e) [print (join "Salut " e)]]] fen: layout fen view fen

Hi, Bertrand, Unfortunately (or perhaps fortunately ;-), I am not familiar with Microsoft Word, but I certainly understand the concept. This is *not* pretty, but I believe that it demonstrates the concept of adding to a layout after it has been laid out. Hopefully the concept show through that one can add additional "subfaces" to the pane of a face. This example shows a quick and dirty approach, but I am sure that you would want to add better text management, do some refactoring and make it more generic. svv: system/view/vid data: [ "Scott" "123 Main" "Carl" "456 Maple" "Bertrand" "789 Oak" ] lo-func: func [txt-str] [ new-pane: make select svv/vid-styles 'text [ text: txt-str color: 142.128.110 size: 200x200 ] if not empty? b/pane [ pane-count: length? b/pane new-pane/offset: b/pane/:pane-count/offset + 0x34 ] new-pane ] lo: layout [ origin 10x10 b: box 200x200 button "Add Info" [ my-text: rejoin [data/1 "^/^-" data/2] next-pane: lo-func my-text append b/pane next-pane show b data: skip data 2 if tail? data [data: head data] ] do [b/pane: copy []] ] view lo ;############## Please let me know how it works and if this is closer to that which you seek and if you need further comments to explain the functionality. --Scott Jones

Yes. Attention to line break. view layout [ size 200x400 button "add button" [ for e 1 10 1 [ insert tail face/parent-face/pane make-face/offset/spec 'button 20x30 + (0x20 * e) [ text: join "button-" e ] ] show face/parent-face ] ] --- Ciao Romano

The way i use is to place different boxes, in my first layout.. Those boxes could have 0x0 offset and 1x1 size. (i.e boxA) Each one them could have a content when you want, even when the first layout object is done and shown. The content is another layout. You just has to 1) transform the [] into a layout 2) declare that the layout-number2 is boxA/pane 3) declare boxA/size: 200x200 i.e. 4) declare boxA/offset is 10x10 5) show boxA All the procedures I used is in the article, too. http://www.rebolfrance.org/articles/debutantvid/debutantvid.htm But I'm sure there's other ways to do it.. I do that, because I have problems to handle subpanels, access and refresh them.

Thanks to Scott, it is what I wanted to realize. Of course some modifications are necessary, but it works. But simply if you could tell me more about the following: <svv: system/view/vid> Also thanks to Philippe, I feel more confortable now with all that knowledge to go a little bit further with REBOL.

Hi, Bertrand, Some of REBOL itself is written in code that is platform specific, and these parts are referred to as native. A surprising amount of REBOL is coded in REBOL. The first level of this code is also called the mezzanine. One can get at this level through the path word 'system. Warning: it makes calls itself, and used to lock up when probed with "probe system". The recursion is limited now for probe, but the code is long, so it is usually more helpful to look at sections as needed.
>> probe first system
[self version build product components words license options user script console ports network schemes error standard view stats locale user-license]
>> probe first system/view
[self screen-face focal-face caret highlight-start highlight-end title-size resize-border no-resize-border line-info VID event-port debug pop-face pop-list wake-event window-feel]
>> probe first system/view/vid
[self verbose warn word-limits vid-feel icon-image radio.bmp radio-on.bmp vid-colors vid-face state-flags vid-words vid-styles track error warning facet-words fw-with fw-feel spot expand-specs grow-facets do-facets next-tab choice-face set-edge] So one can work ones way through the path refinements to get to sections of the source code. svv was assigned to this path to merely keep the code from wrapping. vid-styles is a block that contains all the vid styles found in VID. I merely used a select to get to the face template for text. There are other ways to make faces, and in fact Romano shows another way in an earlier submission. TIMTOWTDI There is more than one way to do it" (Thanks, Larry Wall) There are benefits to some over others, and I don't pretend to be an expert to know in which situations where one is better than another. As a final note about the REBOL system, one can get the source code for mezzanine-level or higher functions using source.
>> source source
source: func [ "Prints the source code for a word." 'word [word!] ][ prin join word ": " if not value? word [print "undefined" exit] either any [native? get word op? get word action? get word] [ print ["native" mold third get word] ] [print mold get word] ] If you do source on the function that Romano uses, make-face, you will see that at one point it gets a base style by using get-style which ends up doing essentially what I did. 'make-face is a more complete and generic wrapper around what I did manually. I hope this submission makes sense. And, by the way, reading the system source is great way to learn some great tricks from the masters: the RT folks themselves! On a freshly started REBOL console, paste the following and *be patient*: echo %//windows/desktop/system.txt probe system quit Then puruse system.txt to your hearts content. --Scott Jones

Hi Bertrand, << But simply if you could tell me more about the following: <svv: system/view/vid> >> svv is defined as a shortcut to system/view/vid, to save typing. There are a couple others as well.
