for GtkWidget::button_press_event and GtkWidget::button_release_event
signals you do:
gint
my_button_press_event_handler (GtkWidget          *widget,
                               GdkEventButton     *event,
                               gpointer            func_data)
{
  printf ("button %d\n", event.button);
  return TRUE;
}

for the GtkButton::clicked signal you could fetch the current
event via gtk_get_current_event() which will be of type GDK_BUTTON_RELEASE
in the clicked handler. but also the event.button will always be 1 since
GtkButton::clicked will only be emitted if mouse button 1 was released.

maybe you should just call gtk_widget_draw (image, NULL) on your image to
force expose it and ignore the drawing queue.
