Re: Passing keypress events

[roel lufthansa com]

This is sort of what I have now, but I want to get rid of this. This approach will
force me to hardcode accellerators. I want to use the dynamic rebinding (or however
is is called :-) ) from gtk in the menu (select a menu item with the mouse without
clicking on it, press backspace or delete, and press the key you want to set the 
shortcut to). This is so that users will be able to remap keys that are used in the
command line apps that they use inside the terminal to keys that are not used.
Otherwise I'll have to make a complete configuration dialog to set these key bindings,
and then keep track of that (actually that's what I have now, but this is duplicate 
effort and more difficult for users). So, I need a way to send keypresses to some 
widget that will process the currently set accelerators, and will call the functions
that are associated with those menu items... The question is, which widget is that...

cheers,
