supportsOpaqueRegions	back to summary
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. Returns:boolean Whether this NGNode implementation supports opaque regions. This could also have been implemented via an interface that some NGNodes implemented, but then we'd have instanceof checks which I'd rather avoid. Annotations @Override
