I am writing a program in OpenGL and I need some sort of interfacing

  • 0

I am writing a program in OpenGL and I need some sort of interfacing toolbar. My initial reactions were to use a GUI, then further investigation into C++ I realized that GUI’s are dependent on the OS you are using (I am on Windows). Therefore, I decided to use QT to help me.

My Question is if I am taking the best/appropriate approach to this solution. Am I even able to write my OpenGL program and have the GUI I want to create interface with the C++ code to do what I want it to do.

For example, If I create a simple “control panel” with arrows in each direction. And on screen I have a box object created by glut can I interface the arrows to be clicked on and interact with the openGL program to move the box?

    Using Qt is coherent for your problem: it provides good integration of OpenGl through the QtOpenGL module.

    1. Derive your display classes from QGLWidget (until Qt 4.8) or from QOpenGLWidget (since Qt 5.4) and implement virtual methods paintGL() etc.
    2. You will have access to the Qt’s signal and slot system so that you will be able to catch Gui events and update the OpenGl display.
