Class FloatingPaletteHandler

java.lang.Object
  de.sciss.gui.FloatingPaletteHandler

All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener

public class FloatingPaletteHandler
extends java.lang.Object
implements java.awt.event.ActionListener

Regular windows and floating palettes register themselves with a a FloatingPaletteHandler. The handler then takes care of hiding and showing the palettes when the application becomes active or inactive (i.e. one of the regular windows has focus or none of them). The class is closely based on FloatingPaletteHandler14 v2.0 by Werner Randelshofer (Quaqua project).
