[Glade-users] libglade, GtkDrawingArea, GdkEvents ?

[pop mail yahoo fr listsmx ximian com (oogothoo)]

Thanks for your help !
I modify my code, with the same file glade :

#include <gtk/gtk.h>
#include <glade/glade.h>

gboolean
motion_notify_event(GtkWidget *widget,
                                   GdkEventMotion *event)
{
        g_print("%f %f.\n", event->x, event->y);
        return TRUE;
}



gboolean
button_release_event(GtkWidget *widget,
                                    GdkEventButton *event)
{
        g_print("bouton =3D %d.\n", event->button);
        return TRUE;
}


int
main(int argc, char **argv)
{
        GladeXML *xml;

        gtk_init(&argc, &argv);
        glade_init();
=09
        xml =3D glade_xml_new("test.glade", NULL, NULL);

        if(!xml)
        {
                g_warning("error loading gtk.glade");
                return 1;
        } else {
                gtk_widget_add_events(glade_xml_get_widget(xml, "drawingarea"),
                                      GDK_BUTTON_RELEASE_MASK
                                      | GDK_POINTER_MOTION_MASK);

                glade_xml_signal_connect(xml,
                                         "on_drawingarea_motion_notify_event",
                                         G_CALLBACK(motion_notify_event));

                glade_xml_signal_connect(xml,
                                         "on_drawingarea_button_release_event",
                                         G_CALLBACK(button_release_event));
        =09
                glade_xml_signal_connect(xml,
                                         "on_window_destroy",
                                         G_CALLBACK(gtk_main_quit));

                gtk_main();
                return 0;
        }
}


But only the 'motion_notify_event' work.=20
'button_release_event' doesn't work but no error in log...

If i delete the call to gtk_widget_add_events, event on drawingarea events=
=20
doesn't work.

What is the problem ?
