Disabling GtkAccelGroup

[OndÅej TÅma <konference webjet cz>]

Hi,

i have little problem with GtkAccelGroup. I'm creating application
for mind maps (will be opensource and free). There are node's which i
want to copy, cut and paste. This actions are on top of application, so
it is in main menu in main window and i want to accel them (Ctrl-C,
Ctrl-X and Ctrl-V).

But when i do this in top of application in main window menu, all these
accels didn't work in child - for example when i edit node with
GtkEntry.

So, question is, is there some way to disabling GtkAccelGroup for some
time ? Or something like this, which i could to use for good work with
child access in special times (editing text) ?

Thank's a lot for your answers.
