    GTK DrawArea OpenGL

    I am writing a program that needs to display graphs. Right now I am using Cairo which works well except it is really slow. Drawing 1200 lines locks up my computer (i7 CPU and gtx285 graphics card).

    I only found examples to use Cairo with GTK DrawingArea can I use OpenGL instead or is there a way to cairo to run faster?

    Thanks,
    Justin

    If you want to use OpenGL inside of GTK+ take a look at gtkglext it gives you a gtk widget that you can create an OpenGL context inside of.
