Renders labels with Qt.
This class uses Qt to render labels and compute sizes. The labels are rendered to a QImage, then EndFrame() converts that image to a vtkImageData and textures the image onto a quad spanning the render area.

Methods invoked by print to print information about the object including superclasses.
Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkLabelRenderStrategy.
