[pygtk] getting the right focus

[eric texier]

Sorry if the example is too  long, it's not working the way I would
like. 
I would like to toggle visibility of the local menubar with a key
stroke('@'). but only until I enter 'return' in one of the entry, the
correct menubar(through its evenBox) is  getting the focus

There is 2 things that are happening that I don't understand:
- I only set a enter_notify_event callback, but button_press is
activing it too.
- why after grab_focus, I am not  getting the eventBox focus. Only
after activating the entry, I am getting the key press.

'@' (toggle the visibility of the local menubar)

Hope it's clear enough. I am also pretty newby at pygtk so if there
is better way to do that I will like to hear about it. For example,
it is possible to have accelerator on something else than a window?
Thanks,
Eric
