EventBox doesn't emit Key Events.

[Joaquim Duran <joaquinduran adtelecom es>]

Dear All,

I'm interested in capture the key press event emitted by an Event Box
container.

I've modified the eventbox sample included in the GTKmm box to accept
button pressed events and key pressed events. The result is the button
pressed events are emitted (the window is closed), but not the key
pressed events (the window is not closed).

I've no idea if I'm doing something wrong or if this is a bug from the
library.

Gtkmm: 2.12.1
Gtk: 2.12.1
Glib: 2.14.2

Thanks in advance.

Thanks and Best Regards,
Joaquim Duran
