Subject Issues with timing??
Date Fri, 07 Apr 2006 13:55:34 GMT
OK, I'm still doing whiteboarding over a network.  I've run into some
kind of issue with waiting for the GVT tree.  I've been calling
invokeAndWait() to ensure one thread is finished before the next thread
starts.  All my threads that update the document are called in the
RunnableQueue.  However, some of these commands cause the document to be
changed.  If you create a new whiteboard or switch pages of a
whiteboard, a new SVGDocument is put in place.  Within the thread that
causes the change, I try to wait for the GVT tree to finish rendering,
but the GVT won't render until the current thread (also in the
RunnableQueue) finished.

 

Is this correct?  Basically I have a timeout while waiting for the tree
to render and after the wait is over, the tree renders.  I think it's
backed up behind my thread in the RunnableQueue.  Can I safely use
invokeLater and guarantee that my threads start AND finish, one after
the other?  Can I "force" the GVT tree to render inside my own thread
instead of waiting for it?  How can I work around this issue?
