Description

The base class of the Gtk+ type hierarchy.

  • Each widget is a represented as a purely abstract data type. It can only be accessed through and the special access functions that are defined in each widget file.

Synopsis

Detail

Object is the base class for all widgets, and for a few non-widget objects such as Adjustment. Object predates GObject; non-widgets that derive from Object rather than GObject do so for backward compatibility reasons.

Methods

makeNewObject :: ObjectClass obj => (ForeignPtr obj -> obj, FinalizerPtr obj) -> IO (Ptr obj) -> IO objSource

Weak references

objectWeakref :: ObjectClass o => o -> IO () -> IO GWeakNotifySource

Attach a callback that will be called after the destroy hooks have been called

objectWeakunref :: ObjectClass o => o -> GWeakNotify -> IO ()Source

Detach a weak destroy callback function

Signals

objectDestroy :: ObjectClass self => Signal self (IO ())Source

Signals that all holders of a reference to the Object should release the reference that they hold. May result in finalization of the object if all references are released.

notifyProperty :: ObjectClass self => ReadWriteAttr self a b -> Signal self (IO ())Source

Register a notify callback that is triggered when the given property has been modified.

  • Note that this callback is triggered even if the actual value of the property has not changed. * Not all attributes are properties. A warning will be generated at runtime if the passed-in attribute is not a property of the class with which it was registered.
