RenderWindowNoUiFile
VTKExamples/Cxx/Qt/RenderWindowNoUiFile
Description
This is a very basic example that shows how to create a Qt window. Typically, one would want to design a form in the QtDesigner (this is shown in RenderWindowUi)
Code
RenderWindowNoUiFile.cxx
#include <QApplication>
#include <vtkSmartPointer.h>
#include <vtkSphereSource.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <QVTKWidget.h>
int main(int argc, char** argv)
{
QApplication app(argc, argv);
QVTKWidget widget;
widget.resize( 256, 256 );
vtkSmartPointer<vtkSphereSource> sphereSource =
vtkSmartPointer<vtkSphereSource>::New();
vtkSmartPointer<vtkPolyDataMapper> sphereMapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
sphereMapper->SetInputConnection( sphereSource->GetOutputPort() );
vtkSmartPointer<vtkActor> sphereActor =
vtkSmartPointer<vtkActor>::New();
sphereActor->SetMapper( sphereMapper );
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
renderer->AddActor( sphereActor );
widget.GetRenderWindow()->AddRenderer( renderer );
widget.show();
app.exec();
return EXIT_SUCCESS;
}
