It isn't possible to connect a event handler to a label, since labels
don't have associated X windows. So you'll need to stick your label
inside another widget, and connect to button press events on that
widget. One possibility, if I remember corrrectly, is the Viewport
widget. (Boxes, the obvious choice, also don't have windows.)
Then do something like
gtk_widget_set_events(mywidget,GDK_BUTTON_PRESS_MASK);
gtk_signal_connect(GTK_OBJECT(mywidget,"button_press_event",
button_press_callback, NULL);
where
static gint
button_press_callback(GtkWidget mywidget, GdkEventButton *event)
{
gtk_menu_popup(GTK_MENU(mymenu),NULL,NULL,NULL,NULL,
event->button);
}
(This is ofcourse, untested)
