      Constructors 
      Modifier Constructor Description
      protected PEEventMulticaster​(java.util.EventListener a, java.util.EventListener b)
      Creates a PEEventMulticaster instance which chains listener-a with listener-b

    • Method Summary

      All Methods Static Methods Instance Methods Concrete Methods 
      Modifier and Type Method Description
      static PEMouseInputListener add​(PEMouseInputListener a, PEMouseInputListener b)
      Adds PEMouseInputListener-a with PEMouseInputListener-b and returns the resulting multicast listener.
      protected static java.util.EventListener addInternal​(java.util.EventListener a, java.util.EventListener b)
      Returns the multicast listener resulting from the addition of listener-a and listener-b.
      If listener-a is null, it returns listener-b; If listener-b is null, it returns listener-a If neither are null, then it creates and returns a new PEEventMulticaster instance which chains a with b.
      void mouseClicked​(PEMouseEvent e)
      Handles a mouseClicked event by invoking the mouseClicked methods on listener-a and listener-b.
      void mouseDragged​(PEMouseEvent e)
      Handles the mouseDragged event by invoking the mouseDragged methods on listener-a and listener-b.
      void mouseEntered​(PEMouseEvent e)
      Handles the mouseEntered event by invoking the mouseEntered methods on listener-a and listener-b.
      void mouseExited​(PEMouseEvent e)
      Handles the mouseExited event by invoking the mouseExited methods on listener-a and listener-b.
      void mouseMoved​(PEMouseEvent e)
      Handles the mouseMoved event by invoking the mouseMoved methods on listener-a and listener-b.
      void mousePressed​(PEMouseEvent e)
      Handles the mousePressed event by invoking the mousePressed methods on listener-a and listener-b.
      void mouseReleased​(PEMouseEvent e)
      Handles the mouseReleased event by invoking the mouseReleased methods on listener-a and listener-b.
      protected java.util.EventListener remove​(java.util.EventListener oldl)
      Removes a listener from this multicaster and returns the resulting multicast listener.
      static PEMouseInputListener remove​(PEMouseInputListener l, PEMouseInputListener oldl)
      Removes the old PEMouseInputListener from PEMouseInputListener-l and returns the resulting multicast listener.
      protected static java.util.EventListener removeInternal​(java.util.EventListener l, java.util.EventListener oldl)
      Returns the multicast listener obtained after removing the old listener from listener-l.
      If listener-l equals the old listener OR listener-l is null, returns null.
      Else if listener-l is an instance of AWTEventMulticaster, then removes the old listener from it.
      Else, returns listener l.
