hello
I have suddenly discovered a problem with my mousepickbehavior class in the
processStimulus method
I display a graph in 3d and you can double click on the nodes and edges to select one.
When I start my application and then click 3x on a node instead of 2x (so a triple
click :)) I get the following exception :
Exception occurred during Behavior execution:
java.util.NoSuchElementException: No more criterion
at
javax.media.j3d.WakeupCriteriaEnumerator.nextElement(WakeupCriteriaEnumerator.java:132)
at
app.graph.view3d.behaviors.MousePickBehavior.processStimulus(MousePickBehavior.java:74)
at javax.media.j3d.BehaviorScheduler.doWork(BehaviorScheduler.java:167)
at javax.media.j3d.J3dThread.run(J3dThread.java:256)
Note that I only get this exception when I haven't selected a node before with
a doubleclick. So once the application is running after a correct first selection I
may tripleclick all I want , it won't throw an exception. I see
that the processStimulus method actually has a WakeUpCriteriaEnumerator argument
instead of a Enumeration object as argument as stated in the documentation. Why is
this? Is there extra functionality in the
WakeUpCriteriaEnumerator class that may be useful in my case? Apparently the
WakeUpCriteriaEnumerator class ins't public anyway.
Is there anyone who has encountered this problem also?
btw : here is my code in the processStimulus method :
public void processStimulus(Enumeration aCriteria)
{
WakeupOnAWTEvent crit = (WakeupOnAWTEvent)aCriteria.nextElement();
java.awt.AWTEvent[] events = crit.getAWTEvent();
MouseEvent event = (MouseEvent)events[0];
//process event
.......
thanks,
mattie
