Method Summary

Modifier and TypeMethod and Description
private void
calculatePositionAndClipping()

protected RectBounds
computeOpaqueRegion(RectBounds opaqueRegion)

Overrides com.sun.javafx.sg.prism.NGNode.computeOpaqueRegion.

Computes and returns the opaque region for this node.

protected void
doRender(Graphics g)

Overrides com.sun.javafx.sg.prism.NGNode.doRender.

Invoked only by the final render method.

protected boolean
hasOpaqueRegion()

Overrides com.sun.javafx.sg.prism.NGNode.hasOpaqueRegion.

Called only on NGNode subclasses which override supportsOpaqueRegions() to return true, this method will return whether or not this NGNode is in a state where it has an opaque region to actually return.

hasOverlappingContents()

Implements abstract com.sun.javafx.sg.prism.NGNode.hasOverlappingContents.

protected boolean
supportsOpaqueRegions()

Overrides com.sun.javafx.sg.prism.NGNode.supportsOpaqueRegions.

Gets whether this NGNode supports opaque regions at all.

protected RectBounds computeOpaqueRegion(RectBounds opaqueRegion)

Computes and returns the opaque region for this node. This method

protected void doRender(Graphics g)

Overrides com.sun.javafx.sg.prism.NGNode.doRender.

Doc from com.sun.javafx.sg.prism.NGNode.doRender.

Invoked only by the final render method. Implementations of this method should make sure to save & restore the transform state.

protected boolean hasOpaqueRegion()

Overrides com.sun.javafx.sg.prism.NGNode.hasOpaqueRegion.

Doc from com.sun.javafx.sg.prism.NGNode.hasOpaqueRegion.

Called only on NGNode subclasses which override supportsOpaqueRegions() to return true, this method will return whether or not this NGNode is in a state where it has an opaque region to actually return. If this method returns true, a subsequent call to computeOpaqueRegion(com.sun.javafx.geom.RectBounds) must return a non-null result. Any state used in the computation of this method, when it changes, must result in a call to invalidateOpaqueRegion().

protected boolean supportsOpaqueRegions()

Overrides com.sun.javafx.sg.prism.NGNode.supportsOpaqueRegions.

Doc from com.sun.javafx.sg.prism.NGNode.supportsOpaqueRegions.

Gets whether this NGNode supports opaque regions at all. Most node types do not, but some do. If an NGNode subclass is written to support opaque regions, it must override this method to return true. The subclass must then also override the computeDirtyRegion method to return the dirty region, or null if the node in its current state doesn't have one. This method is intended to be immutable.
