This section describes the remaining GnomeCanvasItem methods, including
unrealize, map, and
The GnomeCanvasItem class
has a slot in its vtable called
event; this is the only
GnomeCanvasItem class function associated with a
signal. None of the stock canvas items implement a
default handler for
event, but of course your own canvas item could.
The return value of event
works just like the GtkWidget
"event" signal; if the last
signal handler returns
FALSE, the event is propagated to the item's
parent item (by emitting the
event signal on the parent), if TRUE propagation ends.
