2003-09-15 Matthias Clasen <maclas@gmx.de> * gtk/gtkactiongroup.[hc]: (gtk_action_group_add_radio_actions): (gtk_action_group_add_radio_actions_full): Add value parameter to allow setting the currently selected group member before connecting signals. (GtkToggleActionEntry): Separate struct for constructing toggle actions, including a boolean to initialize the action state before connecting signals. (gtk_action_group_add_toggle_actions): (gtk_action_group_add_toggle_actions_full): New functions to construct toggle actions from an array of GtkToggleActionEntries. * demos/gtk-demo/appwindow.c: * tests/testactions.c: * tests/testmerge.c: Adjust to new action group API. * gtk/gtk-sections.txt: Add gtk_action_group_add_toggle_actions[_full].
