## com.trolltech.qt.gui
Class QPrintEngine

    java.lang.Object
      com.trolltech.qt.internal.QSignalEmitterInternal
          com.trolltech.qt.QSignalEmitter
              com.trolltech.qt.QtJambiObject
                  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()`.

See also:
  `QPaintEngine`.

Nested Class Summary
`static class` | `QPrintEngine.PrintEnginePropertyKey` This enum is used to communicate properties between the print engine and `QPrinter`.

Constructor Detail

### QPrintEngine

    public QPrintEngine()

Method Detail

### abort

    public abstract boolean abort()

  Instructs the print engine to abort the printing process. Returns true if successful; otherwise returns false.

### metric

    public abstract int metric(QPaintDevice.PaintDeviceMetric arg__1)

  Returns the metric for the given `id`.

### newPage

    public abstract boolean newPage()

  Instructs the print engine to start a new page. Returns true if the printer was able to create the new page; otherwise returns false.

### printerState

    public abstract QPrinter.PrinterState printerState()

  Returns the current state of the printer being used by the print engine.

### property

    public abstract java.lang.Object property(QPrintEngine.PrintEnginePropertyKey key)

  Returns the print engine's property specified by `key`.

See also:
  `setProperty()`.

### setProperty

    public abstract void setProperty(QPrintEngine.PrintEnginePropertyKey key,
                                     java.lang.Object value)

  Sets the print engine's property specified by `key` to the given `value`.

See also:
  `property()`.
