Re: key-release-event not detected

[carlos pehoe civil ist utl pt (Carlos Pereira)]

Try: gtk_widget_set_events 
as I suggested before, instead of: gtk_widget_add_events,
they are not the same (but I guess you already did it...)

key release events work fine for me, though I am setting 
the mask in a large drawing area, not directly on the 
top window, that might be worth to investigate also.

so if everything goes wrong, I suggest you write a 
10-line test program (hello world style) and after 
you get key release events with it, it's much easier 
to understand what the problem really is.
