/** 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).
