Hello,
I've created a bug in Mantis for this
http://www.vtk.org/Bug/view.php?id=15840
Looking at the code in QVTKWidget.cxx, here is the part that may be causing
the problem, because it handles the reparenting part...
*/*******************************************************************************/*
*if(e->type() == QEvent::ParentAboutToChange)*
* {*
* this->markCachedImageAsDirty();*
* if (this->mRenWin)*
* {*
* // Finalize the window to remove graphics resources associated with*
* // this window*
* if(this->mRenWin->GetMapped())*
* {*
* this->mRenWin->Finalize();*
* }*
* }*
* }*
* else if(e->type() == QEvent::ParentChange)*
* {*
* if(this->mRenWin)*
* {*
* x11_setup_window();*
* // connect to new window*
* this->mRenWin->SetWindowId( reinterpret_cast<void*>(this->winId()));*
* // start up the window to create graphics resources for this window*
* if(isVisible())*
* {*
* this->mRenWin->Start();*
* }*
* }*
* }*
*/*******************************************************************************/*
Were there any significant changes in the methods GetMapped() / Finalize()
/ Start() of vtkRenderWindow (or children implementation) during the
development of the new rendering backend that may lead to such a crash :
