QT3D
-
Actually the Qt3D: Basic Shapes C++ Example is a widget application.
It uses a QWindow container embedded into a widget to display OpenGL context but you could easily switch that to(QOpenGLWidget.
There are a couple of (non Qt3D) examples of QOpenGLWidget like the Cube OpenGL ES 2.0 Example. -
Thank you Chris,
I've tired to play with the "Qt3D: Basic Shapes C++ Example". I put the example in my Mainwidow Environment, an want to replace the main.cpp by the "on_application ..."-routine from the mainwindow program.
I works but it shows me only a white screen. I checked it serveral times.
I have no idea what is wrong?
