No, events can be eaten by native (GTK) controls before the wx frame 
work even know about them. In order to get all the events I need to 
handle them at the application level, which means I pass them on or not 
based on the type of control. If we need fine grain control I may have 
to have someway of overriding whether a control instance gets keys or 
not (or going further allowing a callback to allow a decision as to 
whether a particular key should be passed or not).
