Add predicates for types of widgets.

Reported by: A.Simon@… Owned by: somebody

Component: general (Gtk+, Glib) Version:
Keywords: Cc:


It would be useful to have predicates for each widget type that can test an object if it is of that type. At the moment we need to use the castTo* functions and catch the error message that is returned if the cast failed.

  • version 0.9.11 deleted

I have sent a patch to the devel list that does this by way of an isA function and gType* functions. You can use it like so...

when (obj `isA` gTypeWidget) $ doSomething $ castToWidget obj

Since this is now available as typeInstanceIsA in module System.Glib.GType I close this request.
