[FXRuby] How to capture key events

ruby-talk
1

I have a simple gui that consists of mostly just a FXText object, and I
would like to react to keys pressed such as q or space. I am fairly new
to Fox, and haven’t been able to glean the answer from any of the Fox or
FXRuby docs online.

For most widgets, you can intercept the SEL_KEYPRESS and SEL_KEYRELEASE
messages when a key goes down (or up):

 aWindow.connect(SEL_KEYPRESS) do |sender, sel, event|
   if event.code == KEY_q
     puts "q key was pressed"
   end
 end

 aWindow.connect(SEL_KEYRELEASE) do |sender, sel, event|
   if event.code == KEY_q
     puts "q key was released"
   end
 end

Hope this helps,

Thanks, that did the trick! Now, I can’t figure out how to let the
FXMainWindow capture the event instead of the FXText object (it’s
read-only text; I don’t care about keystrokes in the FXText object in
the least).
