Has anyone seen how to add mouse button options to draw ellipses and rectangles? This may be a beginner question, but I just picked a forum to post. Much appreciated for any help
OpenGL doesn’t have mouse support at all.
What your looking for would be a feature of whatever API your using to draw the window, like GLUT, SDL, win32, etc.
Either way, the docs for that API should tell how to do what you want.
