Detailed Description

Gtk::Object is the base class for all widgets, and for a few non-widget objects such as Gtk::Adjustment.

Gtk::Object predates Glib::Object; non-widgets that derive from Gtk::Object rather than Glib::Object do so for backward compatibility reasons.

The most interesting difference between Gtk::Object and Glib::Object is the ability to use Gtk::manage() to delegate memory management to the container widget. Gtk::Objects can also be explicitly deleted at any time, instead of using only reference-counting, and container widgets can respond when their child objects are being deleted (for instance by removing the widget).

Member Function Documentation

GtkObject* Gtk::Object::gobj ( )

inline

Provides access to the underlying C GtkObject.

const GtkObject* Gtk::Object::gobj ( ) const

inline

Provides access to the underlying C GtkObject.

Glib::PropertyProxy< void* > Gtk::Object::property_user_data

(

)

Anonymous User Data Pointer.

Returns

A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly< void* > Gtk::Object::property_user_data

(

)

const

Anonymous User Data Pointer.

Returns

A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

Friends And Related Function Documentation

Gtk::Object* wrap ( GtkObject *  object, bool  take_copy = false  )

related

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns

A C++ instance that wraps this C instance.
