| | '''OpenGL extension MESA.resize_buffers |
| | |
| | This module customises the behaviour of the |
| | OpenGL.raw.GL.MESA.resize_buffers to provide a more |
| | Python-friendly API |
| | |
| | Overview (from the spec) |
| | |
| | Mesa is often used as a client library with no integration with |
| | the computer's window system (an X server, for example). And since |
| | Mesa does not have an event loop nor window system callbacks, it |
| | cannot properly respond to window system events. In particular, |
| | Mesa cannot automatically detect when a window has been resized. |
| | |
| | Mesa's glViewport command queries the current window size and updates |
| | its internal data structors accordingly. This normally works fine |
| | since most applications call glViewport in responce to window size |
| | changes. |
| | |
| | In some situations, however, the application may not call glViewport |
| | when a window size changes but would still like Mesa to adjust to |
| | the new window size. This extension exports a new function to solve |
| | this problem. |
