Qt is better ported for Windows and looks more native than GTK. Gimp on windows, for example, looks very strange, because most of its dialogs are not Windows dialogs. Qt can use native Window dialogs like Open/Save which makes it feel better as a framework. And yes, Qt is a framework, not only a GUI Widget.

Is it possible to enable OpenGL with Qt Quick?

But it is also possible to manually select OpenGL as the active graphics API on platforms where this is supported. For more details on enabling OpenGL with Qt Quick, see scenegraph renderer documentation.

Why use qopenglshaderprogram instead of Raw OpenGL?

Here is the code that loads the shaders and initializes the shader program By using QOpenGLShaderProgram instead of raw OpenGL we get the convenience that strips out the highp, mediump, and lowp qualifiers on desktop OpenGL, where they are not part of the standard.

How do I render a qpainter in OpenGL?

The OpenGLWindow subclass can either reimplement render () for OpenGL based rendering, or render ( QPainter *) for rendering with a QPainter. Use OpenGLWindow::setAnimating (true) for render () to be called at the vertical refresh rate, assuming vertical sync is enabled in the underlying OpenGL drivers.

Do not render to qopenglcontext before it receives its first expose?
