[vtkusers] Qt4 QMdiArea::addSubWindow() deletes VTK render window

[John Platt]

Hi all,

 

When I add a child window derived from QVTKWidget to a QMdiArea,

 

    QMdiSubWindow* mdiSubWindow = mdiArea->addSubWindow( mdiChild );

 

the VTK render window created in the mdiChild constructor

 

MdiChild::MdiChild()

{

    setAttribute(Qt::WA_DeleteOnClose);

    isUntitled = true;

 

    // QT/VTK interact

    ren = vtkRenderer::New();

    this->GetRenderWindow()->AddRenderer( ren );

}

 

is deleted when addSubWindow() returns.

 

Calling GetRenderWindow() again appears to fix the problem. 

 

I was wondering if anybody else using QMdiArea has had the same problem 

( Qt 4.3.1 open source edition, VTK 5.1, VS6, Win XP ).

 

TIA

 

John.
