"focus-out-event" is emitted when a widget that can take keyboard focus loses the focus. It makes no sense for containers to have keyboard focus because they do not take input from keyboard. A particular input widget inside the container should have the focus. You can make an event box to take keyboard focus using gtk_widget_set_can_focus() but this is useless. It will prevent the user from tabbing to the child widgets of the event box. Instead he will be able to tab to the event box which will look to him like mysteriously losing focus because the event box is not an input widget. So just connect to signals of the actual input widgets. Yeti _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
