[vtkusers] Refresh issue with QVTKWidget

[Guillaume Dumont]

Hi all,

I am coming for help after searching a solution for a long time that I
cannot seem to figure out.

To put my problem in context, I am using QVTKWidget from VTK 6.1 inside one
of the widgets I wrote. I decided not to use the QVTKWidget directly but
rather hide it from the user of the widget. My class looks like it:

​class MyWidget: public QWidget
{
   ...
public:
   // my overkill render method that I call after a change in my scene
   void updateRender()
   {

        this->m_vtkRenderer->GetRenderWindow()->Render();
this->m_vtkRenderer->GetRenderWindow()->GetInteractor()->Render();
m_vtkWidget->update();
m_vtkWidget->updateGeometry();
this->update();
this->updateGeometry();
   }
protected:
   QVTKWidget* m_vtkWidget;
};​

​Now the problem: when the camera location is changed programatically
(reset or specific position)​, only the middle rectangle is rendered. Until
I resize the window or play with the renderer enough, the full renderwindow
is rendered.

Here is what it looks like (sorry, the model is zoomed in):
