Hello,

1) If you want to completely ignore some key events you may use key snooper. 
It's very easy to set/remove it and you will be sure that no one widget will get 
these events.

2) If you want to ignore key events for special widget only you can set a filter 
on "key-press-event", like the Jean and Carlo said. But this can be somewhat 
painful, because of many possible tricks. Like the case when widget has some 
logic on "key-release-event" or another signal handler that runs before yours...
