[vtkusers] Application crashing on exit

[Rupert Shute]

Hi Ingo,

I did try Mathieu's suggestion, but still the same problem.
Below is a very cut-down version of the code that produces the problem. See
the comment in the destructor.

Regards
Rupert

#include <qnamespace.h>
#include <qapplication.h>
#include <qgl.h>
#include <qwidget.h>
#include <vtkQtObjectFactory.h> 
#include <stdio.h>
#include "vtkRenderWindow.h"
#include "vtkRenderer.h"
#include <qworkspace.h>
#include <qmainwindow.h>
#include <qscrollview.h>


//!Main application window.
class ApplicationWindow : public QMainWindow
{
  Q_OBJECT

    private:  
  vtkRenderer *ren1;
  vtkRenderWindow *renWin;  
  QWorkspace *workSpace;
  QScrollView *vtkScrollView;  
  QWidget *tmpWidget;

 public:
  ApplicationWindow(QWidget *parent=0, const char *name=0, WFlags f=0);
  ~ApplicationWindow();

  public slots:


 signals:  

};

#include "testVtkQt.h"

int main(int argc, char **argv) {  
  vtkQtObjectFactory::RegisterObjectFactory();      
  QApplication::setColorSpec( QApplication::CustomColor );    
  QApplication a(argc, argv);
  ApplicationWindow myMainWin(0, "myMainWin", 0);
  a.setMainWidget(&myMainWin);
  myMainWin.show();   
  a.exec();
}


//Main application window.
ApplicationWindow::ApplicationWindow(QWidget *parent, const char *name,
WFlags f)
  : QMainWindow( parent, name, f )
{  
  // Create the main GUI.
  workSpace = new QWorkspace (this, "workSpace" );
  this->setCentralWidget(workSpace);

  vtkScrollView = new QScrollView(workSpace, "vtkScrollView");
  
  vtkQtObjectFactory::SetQtBase(vtkScrollView->viewport(), NULL);

  ren1 = vtkRenderer::New();
  renWin = vtkRenderWindow::New();
  renWin->AddRenderer(ren1);
  renWin->Start();

   // Do the clever QT VTK bit.  
  tmpWidget = vtkQtObjectFactory::QtWidget(renWin);
  vtkScrollView->addChild(tmpWidget);

  renWin->Render();
}

ApplicationWindow::~ApplicationWindow()
{  
  delete tmpWidget;  // Do I really need to delete this?
  ren1->Delete();
  renWin->Delete();  
  delete vtkScrollView;
}

Sounds okay...

Did you try Mathieu's suggestion ?
Do you have a reproducable mini sample ?

greets
  Ingo
