FXRuby: Reading keystates

[Martin DeMello]

How do I read the pressed state of the shift, ctrl etc keys from within
FXRuby? (And is the correct way to read a Ctrl-A to trap an OnKeypress
for A and check if Ctrl is pressed?)

def onKeypress(sender, sel, event)
p "keysym=#{event.code} state=#{event.state} text=#{event.text}"
if (event.state & CONTROLMASK) != 0
if event.text == 'a'
p "we got a"
end
end
end



elsewhere you must do

widget.connect(SEL_KEYPRESS, methodonKeypress))


(untested)

def onKeypress(sender, sel, event)
p "keysym=#{event.code} state=#{event.state} text=#{event.text}"
if (event.state & CONTROLMASK) != 0
if event.text == 'a'
p "we got a"
end
end
end

I would change one thing, and that is to check the event.code field
instead of the event.text field, i.e.

if (event.state & CONTROLMASK) != 0
if event.code == KEY_a
...
end
end

... also untested

Thanks to both of you!
