How to's

No How to's on the website for some time now. I'm curious to how to go beyond VID dialect and work directly with the rest of /view capabilities. Also, I like the skins-demo that someone has made and would like to get that kinda depth of instruction on make GUI's. Any resources or help anyone can provide. Paul Tretter

Very interesting, thanks!! Ammon

hi! yes that documentation was all I had when I started using view! its a shame that the virtual coordinate system isn't yet supported (or maybe was dropped ?) anyways, to use the view system directly, its actually quite easy because of the OO nature of it. At the very least, This is how I started to play with it: rebol [] gui: make face [] view gui you should have a brown box in a window... real simple... now just replace any object within it with a local (non shared version) and youre off to your own gui design!. Its mainly a question of understanding what each face element does (basically self-descriptive). To get an idea of what elements the face object contained, I just did "probe make face []" and you should get a pretty Also note that most of the face elements are described near the end of the standard view guide (on RT's web site). The how-to on handling events really gives you all you need to start implementing your own custom buttons and gadgets/widgets/controls) to edit any object in the default face, just remember that you must CLONE the object... not just set its values. that is because all faces share the same objects... so if you just set font, for example, it will set the font for all faces... so, if you followed my latest thread (on this list), you'll know that to clone any object within the face, just do: rebol [] gui: make face [ text: "my first custom face" size: 300x50 offset: 100x100 font: make font [ size: 15 style: 'bold ] ] view gui and voila! any other questions? just shoot 'em cheers! -Maxim

Yeah but the text doenst show up. Just a horizontal brown rectangle. Paul Tretter

Thanks Ammon. Can you explain why the 300x50 is need in both make face's. Paul Tretter

Just to make both faces the same size. The default size of a face is, well let's see:

Now, how do I get multiple faces in a face? Thanks!! Ammon

and you append them to pane? Not sure .... just shooting from the hip. Paul Tretter

no go on that. Enjoy!! Ammon

Yes. Type this into your console a line at a time (watch line-wrap): lay: layout [size 300x300] view/new lay append lay/pane make get-style 'button [size: 40x40 color: red] show lay append lay/pane make get-style 'button [offset: 200x100 size: 40x40 color: green] show lay wait none ; and a bit of analysis... probe length? lay/pane ; == 2 type? lay/pane/1 ; == object! probe first lay/pane/1 lay/pane/1/type ; == face lay/pane/1/style ; == FACE Layout returns a face object. Every face object has a pane attribute. So that means every face can have sub-faces, simply if they are added to the pane (with APPEND, for instance). You can imagine a face within a face within a face, accessed like this: lay/pane/3/pane/1 That's the first face in the third face in the window. Also, you can see get-style returns a face from the vid style that you specify. Quite handy for this type of thing. Anton.

Not directly as I would like to do. ;) a: make face [ offset: 100x100 size: 300x50 ;there should be a way to do something like: pane: make face [ a: make face [ pane: make face [ text: "face_a's data" font: make font [ size: 20 style: 'bold ] ] ] b: make face [ pane: make face [ text: "face_b's data" font: make font [ size: 20 style: 'bold ] ] ] ] ] but this doesn't seem to work. I know you can append to a face that is already made, but I want to make it with 'make 'face not with VID. Thanks!! Ammon

See comments below.

hello, yep, and their visual order or depth, depends on their order in the pane list. The topmost face is the last face in the pane list... If you want to program faces directly, I must really suggest the "HOW-TO handle user interface events" guide... its crammed with a lot of information about handling faces... the short scripts will really make you have fun... especially the drag and drop ones. -MAx

This mail was originaly intentended for the list, but for some reason my mailer switched addresses and sent it directly to paul... !?? it explains why the first (or root) face does not show text by default, and how to get it to display text from the root face. note to paul: I've edited the examples and included another one, so you might want to check the mail too. --------------------------------- I'll continue where Ammon Left off... The first Parent face, it seems, is the window description... and in that context, the text attribute sets the window's title name !!! run this example and notice the window's title ... rebol [] gui: make face [ offset: 30x30 size: 200x30 text: "hey!" ] view gui if you want the text to be displayed normally, do the following... rebol [] gui: make face [ offset: 30x30 size: 200x30 text: "hey!" ] view/options gui 'no-title you see, providing the 'no-title option , makes the text behave as normal. but then you have to provide your own window titlebar... In the example I sent to the list, notice that the window titlebar actually does drag the window around... :-) if you want a standard system window border AND some text in the window you'll have to do like Ammon suggested... you need to supply it a face in the pane attribute to display inside it... -MAx
