wxruby users - Nov 2003 - Does wxRuby have event masks or something similar?

I''m trying to capture character events on a frame, using the following
piece of
code (adapted from samples/etc/test.rb):

  def initialize(title)
    super(nil, -1, title, Wx::Point.new(-1,-1), Wx::Size.new(530,590),
Wx::DEFAULT_FRAME_STYLE | Wx::FRAME_SHAPED)
    evt_paint { onPaint }
    evt_char { | evt |
      puts "Got char evt: "+evt.to_s
      if evt.get_key_code.chr =~ /\s/
	next_image
      end
    }
    @bitmap = nil
    @file = nil
  end


(I''ve added the constant for Wx::FRAME_SHAPED to try and allow resizing
programtically.  Doesn''t seem to work, but that''s a seperate
issue).

I''m using a class based on Kevin''s image/png sample that he
sent to the
list earlier.

For whatever reason, my event handler never seems to get called.

Is there some kind of event mask that I need to enable or something?
I know other toolkits sometimes require it...

Your questions always require some interesting research :-)

It took me a little while to figure out that Frame, for some reason, 
does not get key events (nor char events). I don''t see this in the 
wxWindows docs anywhere.

So I added a Panel inside the frame, and did the keyboard handling 
there. Here are my Panel and Frame classes:

###################
class MyPanel < Wx::Panel
   def initialize(parent)
     super(parent, -1, Wx::DEFAULT_POSITION, Wx::Size.new(200,200))
#    evt_key_down do |evt | puts("Key down"); evt.skip; end
     evt_char do | evt |
       puts "Got char evt: "+evt.to_s
       if evt.get_key_code.chr =~ /\s/
         puts("space")
       end
     end
   end
end

class MyFrame < Wx::Frame
   def initialize(title)
     super(nil, -1, title)

     MyPanel.new(self).set_focus
    end
end
###################

Note that I had to set the focus to the panel before it started 
receiving keys. Here, I used set_focus. Or manually clicking in the 
panel area (inside the frame) also works to set the focus.

Also note that if you catch evt_keyXXX, then you must call evt.skip in 
order for the evt_char to fire.
