Modifier	Constructor and 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 and 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.
`java.lang.String`	`toString()`
