# 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.

Since:
  1.5

      `region` - Identifies the portion of the JComponent
      `style` - Style associated with the component
