gtk2hs-cast-th

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 Template Haskell package of gtk2hs-cast, it includes a template for generating a module with instances of the Cast class, defined at gtk2hs-cast-glib.
