Class 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

        public SynthContext(JComponent component,
                            Region region,

                            int state)
        Creates a SynthContext with the specified values. This is meant for subclasses and custom UI implementors. You very rarely need to construct a SynthContext, though some methods will take one.
        Parameters:
        component - JComponent
        region - Identifies the portion of the JComponent
        style - Style associated with the component
        state - State of the component as defined in SynthConstants.
        Throws:
        NullPointerException - if component, region of style is null.
