Hi, I have a specific question on how to retrieve the status of a "GtkMenuItem" which has a check box attached to it (created in Glade). In general I find it difficult to find out where to look for the functions to retrieve the status of all kinds of GTK items ? e.g.: void on_menu_mode_1_activate (GtkMenuItem *menuitem, gpointer user_data) { return; } Best regards, Peter Van Osta Union Biometrica N.V./S.A.
