A new addition to the Qt examples is Qt/MinimalQtVTKApp thanks to Julian Fausty.
I also noticed that four of the existing Qt examples used the same boring image, a tomato coloured sphere on a blue background. These examples were reworked to use Platonic Solids. Additionally, BorderWidgetQt actually didn’t work, it is now fixed. The ShareCameraQt example now uses a cone. As a result, this has vastly impoived the look of the online examples section in vtkGenericOpenGLRenderWindow
I will also look at FourPaneViewer and TouchGestureViewer and maybe bring them across into these Qt examples.
