[ALLY] Re: Layout Bind or Context in stylized Layouts

From: jeff:rebol at: 13-Nov-2000 15:36

Thanks, folks, for your kind words of encouragement. I really enjoy trying to spread to REBOL knowledge when I can (and I'm very much still learning all the time myself!)

Not sure what you mean. A facet is just a field of a face object, like if we have: face: make face [size: 2x2] SIZE is a facet of the face. Other face facets are EDGE, PARA, FONT, FEEL, RATE, etc.. I'm not clear what you mean by "'multi fields and their content".

Well, WITH is a "custom word", or what is referred to in VID as a "FACET word" (even though WITH really isn't typically a facet of a face WITH lets you manually set various other facets in the face when using a VID style). Below are all the current facet words that can be found after a vid style in a layout: edge font para feel effect effects keycode rate colors texts help user-data with bold italic underline left center right top middle bottom plain of font-size font-name font-color wrap no-wrap as-is shadow frame bevel ibevel I can't explain all of them at this point, but most of them are pretty self explanatory. Let's get all crazy and use most every facet word for a single style: view layout [ image edge [size: 10x10 effect: [blur nub] color: 255.255.255] font [name: "courier"] para [origin: 5x15] feel [engage: func [face action event][ face/effect: compose [crop fit colorize ( either action = 'down [ [255.0.0 cross 255.255.255]][[0.255.0 blur]] ) ] show face ] ] effect [colorize 0.255.0] keycode #"q" [unview/all] bold italic left center bottom font-size 32 font-color yellow shadow ibevel wrap "Aaaaaaahhhh!!" ] Neato. :-) At this point we're almost programming directly at the "face level", but in a terser, less verbose, smaller kind of way, if you see what I mean? Using WITH, on the other hand, is like doing IN-LINE FACE PROGRAMMING right in your layouts for extra tight tweaking (sorta like doing in-line assembler! (-:). VID is really a slick short hand for programming faces. Cheers! -jeff
