wxruby users - Jun 2008 - catch all key events in frame?

Hi.

How do I best capture *all* key events in a frame. Specifically: In Albuin I
want to delete selected songs in the playlist when the user presses
''del'' -
no matter what control in the frame happens to be in focused atm. What event
should I bind to and to which control?

(as a side note, the latest svn of albuin fixed the alexs'' problem with
sequel-2.x - never, ever, use depreched methods... :-)

Thanks,
Albin Holmgren

For that sort of thing you could use an accelerator table, which creates 
keyboard shortcuts for menu items. This example makes the
''backspace''
key a shortcut for the Wx::ID_EXIT menu item (assuming self is a Wx::Frame)

    tbl = Wx::AcceleratorTable.new [Wx::ACCEL_NORMAL, Wx::K_BACK, 
Wx::ID_EXIT ]
    self.accelerator_table = tbl

The code for del is Wx::K_DEL. As an aside, Mac laptops don''t generally
have a ''del'' key so it may not be the best choice for a
shortcut.
