protected RectBounds |
computeOpaqueRegion(RectBounds opaqueRegion)
Computes and returns the opaque region for this node.

Shape |
getShape() |
protected boolean |
hasOpaqueRegion()
Called only on NGNode subclasses which override
NGNode.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. |
protected boolean |
supportsOpaqueRegions()
Gets whether this NGNode supports opaque regions at all.

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
NGNode.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 NGNode.invalidateOpaqueRegion()
