Re: redesign of GUI event handling

[Jacob Dawid]

If you'd like to get rid of some more dynamic_casts, I've put a patch here that uses slots and signals instead when possible:

I didn't use signals and slots because they are dependent on Qt. The long term goal was to make an operational layer to the octave interpreter for other multithreaded applications that do not rely on Qt, too. That's why I used the observer pattern instead of signals and slots.
