Hi,
I'm currently working on a QT based project which displays multiple
scenes, each in its own widget. I therefore create a osgViewer::Viewer
instance for every scene.
As soon as I create the second viewer, the widget doesn't respond to
mouse/keyboard events for exactly the amount of time elapsed between the
creation of the first viewer and the second viewer.
I tracked the problem down to osgViewer::Viewer.cpp line 538 (current SVN)
where it says:
/
// initialize the global timer to be relative to the current time.
osg::Timer::instance()->setStartTick();
Here the singleton timer is reset, which should only happen once in the
application lifetime, not per viewer lifetime.
I guarded that call with a global boolean and the problem went away.
Would be great if someone with better knowledge of the osg internals
could fix that issue properly.
Regards
Stefan
