Object Destruction

[Ian King]

Hi,   When a gtk object is explicitly destroyed with gtk_object_destroy, would this cause the emission of any signals that are not associated with the destruction of the object itself (such as deselection within parent, etc..).  Also, is there any way of checking whether a signal connection id for a specific widget is valid, to avoid annoying 'could not find handler' messages.   Thanks for your time   Ian King
