Re: State actions and Glade

[Mitko Haralanov <voidtrance gmail com>]

Hi,

Thank you for your reply. I am not sure what you mean by "GtkToolbar
doesn't implement the GAction interface". In Glade, I can define the
specify the "Action Name" for each individual widget in the Toolbar. Those
action names get automatically linked to the actions that I've defined in
the my GActionEntry array. The only thing that does not work are the Radio
button actions.

Thank you,
Mitko
