[Geany-devel] Super modifier in keybindings - Re: Strange Geany behavior

Ok, it may be a GTK bug, I'll describe whats going on & you can decide
and tell GTK, I've had zero success dealing with them in the past.
Geany keybindings are captured by keybindings.c/on_key_press_event and
don't go to GTK but all other keys go to GTK
When a keybinding is first set Geany does NOT set it as a GTK
accelerator, but the above callback catches it and it works fine, and
if the binding is a key with a modifier the unmodified keys go to GTK
and work fine
When keybindings are loaded from file (ie when Geany is closed and
re-opened) they are set as GTK accelerators but are still caught by
on_key_press_event before GTK. But if the binding is a key with a
modifier the unmodified key goes to GTK which appears to erroneously
interpret it as an accelerator if the modifier in the
gtk_widget_set_accelerator was GDK_SUPER_MASK
The reason you can't set super as a modifier may be that the default
modifier mask is set to block it. I don't know what sets it, mine is
1c00000d which allows super at 4000000 and thats the value when the
accelerator is set and when the keypress event occurs.
Why does Geany process the accelerators twice? Once in Geany and once
in GTK. It seems to me that keybindings don't actually need to be set
as accelerators since on_key_press_event catches them all first, and
that would work around the GTK problem.
