in a previous mail you have written that your tutorial with
MultiDisplayWindow shows the initial scene, but not the modifications
done later. This means that modifications done in the main thread are
transfered to the servers, because they are in the ChangeList for the
same thread the MDW is using.
The changes in the "foo" thread however are only applied to the the main
thread - this does *not* add the changes themselves to the main threads
ChangeList (this is what Dirk meant, when he said ChangeList application
is not transitive).
Now to get your program working you need to get the changes from the
"foo" thread into the main threads ChangeList (because this ChangeList
is distributed to the servers by MDW). You can do this, by calling:
Thread::getCurrentChangeList()->merge(*thread->getChangeList())
This should go into your display function, which would then look like this:
// redraw the window
void display(void)
{
if (needSync==true)
{
needSync=false;
syncBarrier->enter(2);
Thread::getCurrentChangeList()->merge(*thread->getChangeList())
thread->getChangeList()->applyAndClear();
syncBarrier->enter(2);
}
mgr->redraw();
}
Please note that I don't have a cluster here, so I could not test this,
sorry.
Hope it helps,
Carsten
