@hackage / gtk2hs-cast-gtk

This package contains a type class called Cast with a function cast, that is a wrapper for all the castTo* functions of gtk2hs. It makes it easier to write other functions that require a castTo* as a parameter, like xmlGetWidget from glade. The main utility of these packages is to use xmlGetWidgetCast, a version of xmlGetWidget defined in gtk2hs-cast-glade, which has the type: xmlGetWidgetCast :: (Cast widget, WidgetClass widget) => GladeXML -> String -> IO widget.

This is the gtk package of gtk2hs-cast, which contains the instances of Cast for the types in the gtk package from gtk2hs.
