System.Glib.GType

Description

This module implements only the necessities for the GTK binding.

Synopsis

- type GType = CUInt
- typeInstanceIsA :: Ptr () -> GType -> Bool
- glibTypeInit :: IO ()

# Documentation

type GType = CUInt #

typeInstanceIsA :: Ptr () -> GType -> Bool #

Check if an object is of the specific type or derived from it.

- Internally used by Hierarchy.

glibTypeInit :: IO () #

Prior to any use of the glib type/object system, `glibTypeInit` has to be called to initialise the system.

Note that this is not needed for gtk applications using `initGUI` since that initialises everything itself. It is only needed for applications using glib directly, without also using gtk.
