Hi Robert,
one more question.
since in a particular case of my application a ref_ptr<> keeps alive the view
removed with compositeviewer->removeView(view), I get a crash in that case.
I'm building against osg-3.1.4 but I also tries with 3.2.0. And the crash
happens in both cases even if in different parts of code. With 3.2.0 here is
the call stack:
osg100-osgd.dll!osg::GraphicsContext::runOperations() Line 780 + 0x26 bytes
C++
osg100-osgQtd.dll!osgQt::GraphicsWindowQt::runOperations() Line 698 +
0xb bytes C++
osg100-osgd.dll!osg::RunOperations::operator()(osg::GraphicsContext *
context) Line 137 + 0xf bytes C++
osg100-osgd.dll!osg::GraphicsOperation::operator()(osg::Object *
object) Line 53 + 0x19 bytes C++
osg100-osgd.dll!osg::OperationThread::run() Line 426 + 0x26 bytes
C++
osg100-osgd.dll!osg::GraphicsThread::run() Line 41 C++
ot13-OpenThreadsd.dll!OpenThreads::ThreadPrivateActions::StartThread(void *
data) Line 113 + 0xf bytes C++
and the code is the following:
Code:
void GraphicsContext::runOperations()
{
// sort the cameras into order
typedef std::vector<Camera*> CameraVector;
CameraVector camerasCopy;
std::copy(_cameras.begin(), _cameras.end(),
std::back_inserter(camerasCopy));
std::sort(camerasCopy.begin(), camerasCopy.end(),
CameraRenderOrderSortOp());
for(CameraVector::iterator itr = camerasCopy.begin();
itr != camerasCopy.end();
++itr)
{
osg::Camera* camera = *itr;
if (camera->getRenderer()) (*(camera->getRenderer()))(this);
With osg-3.1.4 the crash happens in CompositeViewer::eventTraversal() method
instead, where it seems after the call:
osgViewer::View* masterView = getViewWithFocus() ? getViewWithFocus() :
_views[0].get();
masterView is NULL.
For my understanding there is something related to threads of graphic context
but I didn't understand what should I do to prevent the crash.
Thanks in advance for your help
Gianni
