Enum QGraphicsScene.SceneLayer

java.lang.Object
  extended by java.lang.Enum<QGraphicsScene.SceneLayer>
      extended by com.trolltech.qt.gui.QGraphicsScene.SceneLayer
All Implemented Interfaces:
QtEnumerator, java.io.Serializable, java.lang.Comparable<QGraphicsScene.SceneLayer>
Enclosing class:
QGraphicsScene

public static enum QGraphicsScene.SceneLayer
extends java.lang.Enum<QGraphicsScene.SceneLayer>
implements QtEnumerator

This enum describes the rendering layers in a QGraphicsScene. When QGraphicsScene draws the scene contents, it renders each of these layers separately, in order.

Each layer represents a flag that can be OR'ed together when calling functions such as invalidate or QGraphicsView::invalidateScene().

See Also:
invalidate, QGraphicsView::invalidateScene

Enum Constant Detail

ItemLayer

public static final QGraphicsScene.SceneLayer ItemLayer

The item layer. QGraphicsScene renders all items are in this layer by calling the virtual function drawItems. The item layer is drawn after the background layer, but before the foreground layer.


BackgroundLayer

public static final QGraphicsScene.SceneLayer BackgroundLayer

The background layer. QGraphicsScene renders the scene's background in this layer by calling the virtual function drawBackground. The background layer is drawn first of all layers.


ForegroundLayer

public static final QGraphicsScene.SceneLayer ForegroundLayer

The foreground layer. QGraphicsScene renders the scene's foreground in this layer by calling the virtual function drawForeground. The foreground layer is drawn last of all layers.


AllLayers

public static final QGraphicsScene.SceneLayer AllLayers

All layers; this value represents a combination of all three layers.

Method Detail

values

public static final QGraphicsScene.SceneLayer[] values()
Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:
for(QGraphicsScene.SceneLayer c : QGraphicsScene.SceneLayer.values())
        System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they're declared

valueOf

public static QGraphicsScene.SceneLayer valueOf(java.lang.String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

value

public int value()
Description copied from interface: QtEnumerator
This function should return an integer value for the enum values of the enumeration that implements this interface.

Specified by:
value in interface QtEnumerator

createQFlags

public static QGraphicsScene.SceneLayers createQFlags(QGraphicsScene.SceneLayer... values)

resolve

public static QGraphicsScene.SceneLayer resolve(int value)
