Constructor & Destructor Documentation

◆ GLContextBase()

SDL::GLContextBase::GLContextBase ( WindowBase & window )

inline

Windows users new to OpenGL should note that, for historical reasons, GL functions added after OpenGL version 1.1 are not available by default. Those functions must be loaded at run-time, either with an OpenGL extension-handling library or with GL_GetProcAddress() and its related functions.

GLContextBase is opaque to the application.

Parameters

window the window to associate with the context.

Postcondition: the OpenGL context associated with window.

Exceptions

Error on failure.

Thread safety:: This function should only be called on the main thread.

Since: This function is available since SDL 3.2.0.
