wxruby users - Sep 2010 - Wx::Grid and motion events, bug?

-----BEGIN PGP SIGNED MESSAGE-----

Hi there,

Doesn''t a Wx::Grid get motion events sent? This code demonstrates the
problem:

- --------------------------------------------------------------
#!/usr/bin/env ruby
#Encoding: UTF-8
require "wx"

class MyFrame < Wx::Frame
  include Wx

  def initialize(parent = nil)
    super(parent, title: "Test", size: Size.new(400, 400))
    self.background_colour = NULL_COLOUR

    StaticText.new(self, label: "") #Dummy
    @grid = Grid.new(self, size: Size.new(300, 200))
    @grid.create_grid(10, 10)
    @grid.evt_motion{|e| p "!"; $stdout.flush}
  end

end

class MyApp < Wx::App
  include Wx

  def on_init
    @mainwindow = MyFrame.new
    @mainwindow.show
  end

end

x = MyApp.new
x.main_loop
- --------------------------------------------------------------

If I hover the mouse above the grid, nothing happens, but if I put in a
panel control instead of a grid, it works. Surprisingly, if I changed
the line

@grid.evt_motion{|e| p "!"; $stdout.flush}

to

THE_APP.evt_motion{|e| p "!"; $stdout.flush}

I get motion events for everything but the grid. As soon as the cursor
enters the grid control, no output arrives anymore.
What''s going on here? Is that a bug?

I''m working on Ubuntu Lucid. Here''s the uname -a:

Linux ikarus 2.6.32-24-generic #42-Ubuntu SMP Fri Aug 20 14:21:58 UTC
2010 x86_64 GNU/Linux

and here''s my ruby -v:

ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]

I compiled both Ruby and wxRuby from source.

This problem seems to be quite serious. I just noticed that a Wx::Grid
doesn''t get ANY mouse events sent:
==========================================================#!/usr/bin/env ruby
#Encoding: UTF-8
require "wx"

class MyFrame < Wx::Frame
  include Wx

  def initialize(parent = nil)
    super(parent, title: "Test", size: Size.new(400, 400))
    self.background_colour = NULL_COLOUR

    StaticText.new(self, label: "") #Dummy
    @grid = Grid.new(self, size: Size.new(300, 200))
    @grid.create_grid(10, 10)
    @grid.evt_left_down{|e| p "!"; $stdout.flush}
    @grid.evt_left_up{|e| p "!"; $stdout.flush}
    @grid.evt_motion{|e| p "!"; $stdout.flush}
    @grid.evt_left_dclick{|e| p "!"; $stdout.flush}
    @grid.evt_right_down{|e| p "!"; $stdout.flush}
  end

end

class MyApp < Wx::App
  include Wx

  def on_init
    @mainwindow = MyFrame.new
    @mainwindow.show
  end

end

x = MyApp.new
x.main_loop
==========================================================
No way to get a single "!" out of the above program.
Shall I file a bug on the tracker?
