GtkWidget

Basisklasse für Elemente von Userinterfaces.

Object Hierarchy

GtkObject
`-- GtkWidget

Description

GtkWidget ist eine abstrakte Basisklasse die ihre Nachfolger mit angemessenen Eigenschaften, Methoden und Signalen für anzeigbare Userinterface-Elemente versorgt. Die einzigen Objekte die keine GtkWidget Charakteristiken erben sind GtkTooltips, GtkAdjustment und GtkItemFactory - die alle relativ abstrakte Konzepte sind. Alle anderen Mitglieder der Objekthierarchie sind Nachfolger der GtkWidget Klasse, nehmen Bildschirmplatz in Anspruch, und können als Widget betrachtet werden.

Beachten Sie dass GtkWidget nicht direkt konstruiert werden kann.
