Hi there,

I am writing some minimal code get QVTKWidget working in QTCreator. I am using qmake to compile. The code (see below) compiles correctly but when I try to debug F5, I get a crash as soon as it tries to initialize qvtkwidget.

The paths and libraries seem to be correct. I can compile and run a VTK application when I use vtkRenderWindow.

Any help would be appreciated.

Qt Code: 
  1. #include <QVTKWidget.h>
  2.  
  3. #include <vtkRenderWindow.h>
  4. #include <vtkRenderer.h>
  5. #include <vtkTextSource.h>
  6. #include <vtkVectorText.h>
  7. #include <vtkPolyDataMapper.h>
  8. #include <vtkActor.h>
  9.  
  10. int main(int argc, char *argv[])
  11. {
  12.     QApplication app(argc,argv);
  13.     QMainWindow *mainWindow = new QMainWindow;
  14.     mainWindow->setFixedSize(640,360);
  15.  
  16.    QVTKWidget *widget;
  17.  
  18.     widget = new QVTKWidget;  // <<-- This is where we crash :(
  19.     widget->show();
  20.     mainWindow->setCentralWidget(widget);
  21.  
  22.     vtkTextSource *text = vtkTextSource::New();
  23.     text->SetText("Hello World!");
  24.     text->BackingOff();
  25.     vtkVectorText *vectorText = vtkVectorText::New();
  26.     vectorText->SetText("QVTKWidget");
  27.     vtkPolyDataMapper *textMapper = vtkPolyDataMapper::New();
  28.     textMapper->SetInput(text->GetOutput());
  29.     vtkPolyDataMapper *vectorTextMapper = vtkPolyDataMapper::New();
  30.     vectorTextMapper->SetInput(vectorText->GetOutput());
  31.     vtkActor *textActor = vtkActor::New();
  32.     textActor->SetMapper(textMapper);
  33.     vtkActor *vectorTextActor = vtkActor::New();
  34.     vectorTextActor->SetMapper(vectorTextMapper);
  35.     vtkRenderer *renderer = vtkRenderer::New();
  36.     renderer->SetBackground(0.4,0.6,0.8);
  37.     renderer->AddActor(textActor);
  38.     renderer->AddActor(vectorTextActor);
  39.     vtkRenderWindow *renderWindow = vtkRenderWindow::New();
  40.     renderWindow->AddRenderer(renderer);
  41.     renderWindow->SetStereoTypeToDresden();
  42.  
  43.     widget->SetRenderWindow(renderWindow);
  44.     mainWindow->show();
  45.     app.aboutQt();
  46.     return app.exec();
  47.  
  48. }
