Re: GnomeAnimator Question

[Cody Russell <bratsche dfw net>]

You need to create a GtkEventBox for this. Try something like the
following example. You can check out gnome-ppp-applet under gnome-network
CVS also; it allows mouse events on a GnomeAnimator object.

   GtkWidget *animator;
   GtkWidget *evtbox;
   GtkWidget *tmpbox;

   animator = gnome_animator_new_with_size(22, 22);
   /* Setup your animator.. */

   /* Create an event box to trap mouse events. */
   evtbox = gtk_event_box_new();
   gtk_signal_connect(GTK_OBJECT(evtbox),
                      "button_press_event",
                      GTK_SIGNAL_FUNC(button_press_cb),
                      NULL);
   gtk_widget_set_events(evtbox, GDK_BUTTON_PRESS_MASK);
   tmpbox = gtk_hbox_new(TRUE, 0);
   gtk_container_add(GTK_CONTAINER(evtbox), tmpbox);
   gtk_box_pack_start(GTK_BOX(tmpbox), animator, FALSE, TRUE, 0);

Hope this helps,
   Cody
