What's the right way to draw 2D graphics with opengl support in qt(c++)?

Hi,
What exactly do you want to draw ?
What's your application purpose ?
Are you going to use widgets or Qt Quick ?
What platform are you targeting ? -

What platform are you targeting ?@SGaist Thank you for your reply! I'm coding a program with a large amount of moving text effect for Linux PC platform. And I think it's better not to use QML(I hate Javascript). Up to now, I'm using QLabel with QPropertyAnimation, but it has poor performance. So I wonder what the right way to draw 2D graphics with Hardware Acceleration(like OpenGL) is?

You can use the graphics view framework with a QOpenGLWidget as view port to get acceleration or do everything in OpenGL from Qt directly.

@SGaist I'm now trying with QOpenGLWidget, but I have a new question: How can I render these graphics in another thread?

You have to take special care for the context see the details of the QOpenGLContext class.
You should also take a look at the Qt OpenGL examples, the Threaded QOpenGLWidget is likely one that you will be interested in.
