Scott, congratulations!  I think you found a PHP-GTK bug.

  attributes.event_mask = gtk_widget_get_events (widget);
  attributes.event_mask |= (GDK_EXPOSURE_MASK |
			    GDK_BUTTON_PRESS_MASK |
			    GDK_BUTTON_RELEASE_MASK |
			    GDK_BUTTON1_MOTION_MASK |
			    GDK_BUTTON3_MOTION_MASK |
			    GDK_POINTER_MOTION_HINT_MASK |
			    GDK_POINTER_MOTION_MASK |
                            GDK_ENTER_NOTIFY_MASK |
			    GDK_LEAVE_NOTIFY_MASK);
(from gtkentry.c, around line 1000 in my - admittedly GTK 2 - copy)

- that's where the event_masks for the widgets are originally set.  So
there's your list for GtkEntry, at least..

The notes for gtk_widget_get_events itself say:
 * gtk_widget_get_events:
 * @widget: a #GtkWidget
 *
 * Returns the event mask for the widget (a bitfield containing flags
 * from the #GdkEventMask enumeration). These are the events that the widget
 * will receive.

All I get here from var_dump($widget->get_events()); is int[0].

You can either trawl through GTK src looking for attributes.event_mask, or
you could steal the bit of PHP-GTK code from the signals/events chapter in
the manual and play with the widgets to see what you get.  I don't know if
there's any point in putting in a bug report at this stage, everyone's busy
with PHP 5 development and will then be straight onto PHP-GTK 2.. but
copying this to the dev list anyway so everyone knows it's there.

Sorry,
- Steph
