display a vtkGenericOpenGLRenderWindow in a Qt QOpenGLWindow.
QVTKOpenGLWindow provides a way to display VTK data in a Qt OpenGL context.
QVTKOpenGLWindow extends QOpenGLWindow to make it work with a vtkGenericOpenGLRenderWindow. This is akin to QVTKOpenGLNativeWidget except the OpenGL context is created and managed by QOpenGLWindow (added in Qt 5.4).
While QVTKOpenGLWindow is intended to be a replacement for QVTKOpenGLNativeWidget, there are a few difference between both. Unlike QVTKOpenGLNativeWidget, QVTKOpenGLWindow can target multiple framebuffers and thus allows for stereo-capable applications. QVTKOpenGLWindow API was adapted from deprecated QVTKWidget2.
Since QVTKOpenGLWindow uses QOpenGLWindow to create the OpenGL context, it uses QSurfaceFormat (set using QOpenGLWidget::setFormat or QSurfaceFormat::setDefaultFormat)to create appropriate window and context.
Since QOpenGLWindow (superclass for QVTKOpenGLWindow) is not a subclass of QWidget, a typical usage for QVTKOpenGLWindow is as follows:
QVTKOpenGLWidget provides a wrapper around QVTKOpenGLWindow to manipulate a QVTKOpenGLWindow object as a QWidget instance, it is recommended to use QVTKOpenGLWidget instead of using this class directly.
QVTKOpenGLWindow is targeted for Qt version 5.9 and above.
