          com.trolltech.qt.gui.QPrintEngine

All Implemented Interfaces:

QtJambiInterface

public abstract class QPrintEngine
extends QtJambiObject

The QPrintEngine class defines an interface for how QPrinter interacts with a given printing subsystem. The common case when creating your own print engine is to derive from both QPaintEngine and QPrintEngine. Various properties of a print engine are given with property() and set with setProperty().

QPaintEngine.

Nested Class Summary
