Hi, I'm puzzled by the following: I have an application with a JTabbedPane,
where each pane contains (a reference to) a shared/static
Canvas3D with a scenegraph.
Initially the scene renders well; the first time switching the panels,
during which the viewpoint and several switches are altered, everything
goes well.
After a couple of times switching the tabs, the panel containing the
canvas3D
goes blank (grey), after which the application hangs; in fact all
applications hang,
only the mousepointer can be moved; after a couple of mouse-
clicks the system beeps (as with modal dialogs) and the system freezes and
can only be rebooted the hard way.
No warnings, messages, dumps, whatsoever.
system configuration:
Matrox G400, Java3D 1.2, JDK1.2.2 and JRE1.3
Now, I read bugreports, forum dialogs, and they all point roughly to these
subjects:
- mixing heavyweight/lightweight
- separate threads for Swing and Java3D
I suspect the latter, since the first couple of switches work OK.
Who is experiencing similar problems and has a work-around;
perhaps another setup with container-panels, multiple canvases ?
I cannot have copies of my scenegraph, since it it quite big, and I have
over 10 views of them.
Any help greatly appreciated,
Harry van Stedum
