canvas_example_with_manage.patch

This is another test case. The patch changes the existing example to use
manage() and demonstrates that the destructor is not called.

testcase

When running this program and closing the window, the canvas' destructor gets
called, but not the item's destructor.

------- Comment #2 from Murray Cumming  2006-07-26 16:45 UTC -------
It would indeed be nice if Gtk::manage() worked with Canvas items. That's the
bug here, I think.

I don't know whether libgnomecanvasmm intentionally prevents automatic item
destruction, as we do with gtkmm child widgets, but it makes sense for us to
want it here too. But maybe it's due to code in GtkObject (Gnome::Canvas::Item
derives from Gtk::Object).
