gtk_grab_add problem

[Andrey Dubravin <daa84 inbox ru>]

Hello all!

In the same window I pack GtkTreeView and GtkFrame. GtkFrame contains
buttons and text entry. When gtk_grab_add function was called with
GtkFrame as it's parameter there is no happen!

There is need that interaction with other widgets in the same
application is blocked and all events are delivered to GtkFrame 
widgets (I mean GtkFrame child widgets).

How to do this right?

Thanks!
