public class: CausedFocusEvent [javadoc | source]

java.lang.Object
   java.util.EventObject
      java.awt.AWTEvent
         java.awt.event.ComponentEvent
            java.awt.event.FocusEvent
               sun.awt.CausedFocusEvent

All Implemented Interfaces:
Serializable

This class represents FocusEvents with a known "cause" - reason why this event happened. It can be mouse press, traversal, activation, and so on - all causes are described as Cause enum. The event with the cause can be constructed in two ways - explicitly through constructor of CausedFocusEvent class or implicitly, by calling appropriate requestFocusXXX method with "cause" parameter. The default cause is UNKNOWN.

Method from sun.awt.CausedFocusEvent Detail:
public CausedFocusEvent.Cause getCause() { return cause; }
public static FocusEvent retarget(FocusEvent e, Component newSource) { if (e == null) return null; return new CausedFocusEvent(newSource, e.getID(), e.isTemporary(), e.getOppositeComponent(), (e instanceof CausedFocusEvent) ? ((CausedFocusEvent)e).getCause() : Cause.RETARGETED); } Retargets the original focus event to the new target. If the original focus event is CausedFocusEvent, it remains such and cause is copied. Otherwise, new CausedFocusEvent is created, with cause as RETARGETED.

Method from sun.awt.CausedFocusEvent Detail:

 public CausedFocusEvent.Cause getCause() {
        return cause;
}

 public static FocusEvent retarget(FocusEvent e,
    Component newSource) {
        if (e == null) return null;
        return new CausedFocusEvent(newSource, e.getID(), e.isTemporary(), e.getOppositeComponent(),

}

Retargets the original focus event to the new target. If the original focus event is CausedFocusEvent, it remains such and cause is copied. Otherwise, new CausedFocusEvent is created, with cause as RETARGETED.
