[REBOL] Re: newbie q : value & label in text-lists

From: sags:apollo:lv at: 1-Apr-2004 0:11

Thanks for answers! The next q. is about faces event handling: I would like to use a layout (form) without help of mouse. There was some points in couple of documentation files (view quide and handling events), but no so much. So I am interested to find some more detailed description or some examples about tabing (focusing) throught faces (not just text fields) and more info about "detect" event using. Could you please point me to a link that I missed. brgds Janeks On 31 Mar 2004 at 21:16, Carl Read wrote: On 31-Mar-04, [sags--apollo--lv] wrote:

face/lines provides an index to which line in the list has just been clicked on, so that can be used as a pointer to your data. There's also a face/user-data which could be used to store your values. Using this approach, you could have something like this... REBOL [] my-labels: [ "ten" "eleven" "twelve" "thirteen" "fourteen" "fifteen" "sixteen" "seventeen" "eighteen" "nineteen" ] my-data: [10 11 12 13 14 15 [this is number 16] 17 18 19] view layout [ text-list 200x70 data my-labels user-data my-data [ probe pick face/user-data index? face/lines ] ] (The [this is number 16] is just to show you you could have any data you like in my-data.)
