[Insight-users] using reader as global variable

[john smith]

To be more specific I have tried the following, but still I get errors.
Could somebody tell me what to type?

Thanks in advance

 class MainWindow
{
private:
 typedef   itk::ImageFileReader< ImageType >   ReaderType;
};



MainWindow::MainWindow()
{
  reader = ReaderType::New();
}




void MainWindow::push_button_File()
{
      reader->SetFileName("test.png")
);
}
