Class SynthContext

java.lang.Object

javax.swing.plaf.synth.SynthContext

public class SynthContext
extends Object

An immutable transient object containing contextual information about a Region. A SynthContext should only be considered valid for the duration of the method it is passed to. In other words you should not cache a SynthContext that is passed to you and expect it to remain valid.

1.5
