[vtkusers] VTK, Qt,VtkQt and stereoRendering

[Patrice Aussems]

Hi, 

I'm using Qt, Vtk and the VtkQt-library of Denis Shamoni (I got the same
problem when I use the Matthis Koenig  version) to create an application
that support stereo Rendering.

When I exectute the 
renwin->StereoCapableWindowOn() method I got this following error : 

Warning: In /local/src/VTK/Rendering/vtkXOpenGLRenderWindow.cxx, line
404
vtkXOpenGLRenderWindow (0x8286ff4): Requesting a StereoCapableWindow
must be performed before the window is realized, i.e. before a render.

I know that i have to execute this method before the window is rendered
but i did not use render() in the  source code before.



here is a part of my source code :


QApplication app( argc, argv );
QWidget *widg1 = new QWidget;
widg1->resize(1000, 500);
widg1->show();

ren2 = vtkRenderer::New();
ren2->AddActor(outlineActorl);
ren2->AddVolume(newvollost);
ren2->SetBackground(1,1,1);
ren2->SetActiveCamera(Cameralost);

renwin2 = new vtkQtRenderWindow();
renwin2->StereoCapableWindowOn(); 
renwin2->AddRenderer(ren2);
renwin2->show();


Can anybody help me??
