Thanks a lot! It works. But I found something interesting. Could someone
explain about it?
My code is copied as below. At each click, there are two events passed the
if statement at line6. one is " Button Pressed and Released" pair event,
the other is "Button Clicked" event, The pick behavior was activated twice.
However, only one pickResult has non-null result ( the other pickResult is
null).
Thanks in advance!
1. public void processStimulus(Enumeration criteria)
{
...... ......
2. while (criteria.hasMoreElements()) {
......
3. event = ((WakeupOnAWTEvent)wakeup).getAWTEvent();
4. for (int i=0; i<event.length; i++) {
5. id = event[i].getID();
6. if ((id == MouseEvent.MOUSE_CLICKED) &
((MouseEvent)event[i]).isShiftDown() ) {
int xpos = ((MouseEvent)event[i]).getX();
int ypos = ((MouseEvent)event[i]).getY();
pCanvas.setShapeLocation(xpos,ypos);
pickResult = pCanvas.pickAny();
if (pickResult != null) {
Link lk = (Link)
pickResult.getNode(PickResult.LINK);
System.out.println(lk.getUserData());
}
else
System.out.println("pickResult is null");
} // if shift clicked
} // for i
......
} // while
wakeupOn(buttonPressed);
}
