OpenGL Version in Windows Remote Desktop

Qt shows that the current version and the only supported version in Windows Remote Desktop is 1.1.

Changing the current OpenGL version in Qt

We can change the current OpenGL version by creating a QGLFormat object and calling QGLFormat::setVersion, then passing the format into the QGLWidget's contructor.

NOTE: OpenGL 3.3 is being shown on my current machine with an ATI Radeon HD 2400 Pro graphics card. However, setting the version to 3.2 will give out a lot of warnings and nothing is being drawn on the screen. Setting the version to any versions between 1.x and 2.x will end up with version 3.3. The only version that I can successfully set to is 3.0 only.

The supported OpenGL versions can be queried from QGLFormat in a QGLWidget. The function QGLFormat::openGLVersionFlags returns all the supported versions of the platform.
