Hello all,
I realize that OSG has long since deprecated support for Producer::Viewer in
favor of the Viewer class, but I am hoping that someone might be able to point
me in the right direction..
I am working on updating a display that use OSG 0.9.9 (and for other support
reasons we can't reasonably upgrade to the latest version). We use the
following code to create a viewer and attach a NodeTrackerManipulator object
called "CameraTracker" to track events with a plane node.
Code:
MyCode::initializeViewer()
{
osgProducer::Viewer* viewer;
viewer->setUpViewer(osgProducer::Viewer::STANDARD_SETTINGS);
//perform other setup
nodeTracker = new CameraTracker();
unsigned int num = viewer->addCameraManipulator(nodeTracker);
viewer->selectCameraManipulator(num);
...
viewer->realize();
}
//NodeTrackerManipulator that handles mouse events
bool CameraTracker::handle(const GUIEventAdapter& ea,GUIActionAdapter& us)
{
_thrown = false;
switch(ea.getEventType())
{
case(GUIEventAdapter::PUSH):
{
flushMouseEventStack();
addMouseEvent(ea);
if (calcMovement()) us.requestRedraw();
us.requestContinuousUpdate(false);
_thrown = false;
return true;
}
}
}
The NodeTracker object receives events correctly in the initial implementation,
but I have recently added a simple line of code to embed
the OSG Display inside an MFC dialog window:
Code:
if(m_mfcParentWndHandle != NULL)
{
//Attach OSG viewer display to an existing MFC dialog frame using HWND
viewer->getCameraConfig()->getCamera(0)->getRenderSurface()->setWindow(m_mfcParentWndHandle);
...
viewer->realize();
}
This new code segment attaches the display to the MFC parent correctly, and
FRAME events still seem to be processed (so the display can be redrawn on
frame()), but my NodeTrackerManipulator class doesn't receive mouse events
anymore.
I've looked at the old OSGMFC example, but it doesn't seem to address this
particular situation. I've also tried capturing the MFC mouse events in the
parent dialog, but I can't figure out how to create new GUIEventAdapter objects
that can be passed to my "handle" function.
Does anyone with knowledge of MFC or this old implementation have a suggestion
as to where to look next?
Thanks,
John
