wxruby users - Mar 2008 - Mouse motion example - help

Hi,
I am trying out this example adapted from the wxpython book, but the
mouse motion event does not seem to be captured right. What am I doing
wrong?

Thanks
warrior

# code below
require ''wx''

class MyFrame < Wx::Frame
  def initialize
    super(nil, -1, "My Frame", :size => [300,300])
    @my_panel = Wx::Panel.new(self, -1)
    evt_motion(){ |event| on_move(event)}
    Wx::StaticText.new(@my_panel, -1, :label => "Pos:", :pos =>
[10, 12])
    @posCtrl = Wx::TextCtrl.new(@my_panel, -1, "",:pos => [40, 10])
    show
  end

  def on_move(event)
    @pos = event.get_position
    @posCtrl.change_value("#{@pos}")
  end
end
Wx::App.run{MyFrame.new}

The mouse movement event is directed to the topmost window. So you 
either need to specify that mouse events are captured by the Frame, or 
call the event handler upon the panel which is topmost.

If you think this is different to wxPython, could you post/point to the 
example you mention please?

Either:

  @my_panel.evt_motion { | e | on_move(e) }

or

  capture_mouse
  evt_motion :on_move

Thanks, your suggestion worked. I missed out on the fact that I had to
bind the mouse motion to the panel and not to MyFrame. So,
@my_panel.evt_motion worked exactly as needed.
