Another newbie VID question

[1/8] from: kpeters::mvinc::net at: 4-Oct-2003 12:33

Hi all ~ am wondering why my code below doesn't work toggle_start: toggle 60 "Start" [ flash "we get here" toggle_start/text: "Stop" show toggle_start ] What do I need to make a toggle switch between "Start" and "Stop" every time I press it? Where do I need to look to find which refinements a toggle has? Does it have a 'down' or 'pressed' ? TIA, Kai

This is the answer ... REBOL[] view layout [toggle_start: toggle 60 "Start" [ ;help face face/text: pick ["Stop" "Start"] face/data show face ] ] And here comes the explanation ... Those vid action blocks are turned into functions with the face itself as an argument, named face (be careful, sometimes it's only 'f, IIRC). Now, the commented out "help face" gave me a quick look at what the face contains, among a lot of other things, I found that there's face/data, a boolean value, so I decided "that's it". your toggle_start/text: part was already ok (I just decided to use the word 'face, because it's shorter, and dag'n'droppable ;-) , now we just have to toggle the text depending on face/data (this feature of 'pick has been the source of many long and lively discussions, but it makes for nice short code). I hope that helps, Ingo

Thanks for your very elaborate help, Ingo. It all makes good sense, yet there still is a problem: When I cut & paste your code to my console, the toggle caption does not change on my machine?? Any ideas? Thanks, Kai

I get confused between setting face/text and face/texts too. Try this: REBOL[] unview/all view layout [toggle_start: toggle 60 "Start" [ ;help face face/texts/1: pick ["Stop" "Start"] face/data show face ] ] Sunanda.

After some checks, yes, this has changed between the last official version (1.2.1) and my beta (1.2.8) use "texts/1:!, like Sunanda said. Ingo

Shoulda have said, this _one_ possible answer ...

Which only goes to show, that there's _always_ an easier way in Rebol ... Weeell, I guess that's what you get for wanting to show off ;-) Kind regards, Ingo
