PySide6.QtOpenGL

Detailed Description

The Qt OpenGL module offers classes that make it easy to use OpenGL in Qt applications.

Qt has two main approaches to UI development: PySide6.QtQuick and PySide6.QtWidgets. They exist to support different types of user interfaces, and build on separate graphics engines that have been optimized for each of these types.

It is possible to combine code written in the OpenGL graphics API with both of these user interface types in Qt. This can be useful when the application has its own OpenGL-dependent code, or when it is integrating with a third-party OpenGL-based renderer.

The Qt OpenGL module contains convenience classes to make this type of integration easier and faster.

Qt OpenGL and Qt Widgets

Qt Widgets is typically rendered by a highly optimized and accurate software rasterizer, and the final content reproduced on screen using a method appropriate for the platform where the application is running.

But it is also possible to combine Qt Widgets with OpenGL. The main entry point for this is the QOpenGLWidget class. This class can be used to enable OpenGL rendering for a certain part of the widget tree, and the classes in the Qt OpenGL module can be used to facilitate any application-side OpenGL code.

Qt OpenGL and Qt Quick

Qt Quick is optimized for hardware-accelerated rendering. By default, it will be built on the low-level graphics API most appropriate for the target platform.

For instance, it will default to Direct3D on Windows, whereas on macOS, it will default to Metal. But it is also possible to manually select OpenGL as the active graphics API on platforms where this is supported.

For more details on enabling OpenGL with Qt Quick, see Qt Quick Scene Graph.
