Member Function Documentation

◆ GLContext() [1/2]

constexpr SDL::GLContext::GLContext ( const GLContextRaw resource )

inlineconstexprnoexcept

Parameters

resource a GLContextRaw to be wrapped.

◆ GLContext() [2/2]

SDL::GLContext::GLContext ( WindowParam window )

inline

The OpenGL context will be created with the current states set through GL_SetAttribute().

The Window specified must have been created with the WINDOW_OPENGL flag, or context creation will fail.

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.

GLContext is opaque to the application.

Parameters

window the window to associate with the context.

Postcondition: the OpenGL context associated with window or nullptr on failure; call GetError() for more information.

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

Since: This function is available since SDL 3.2.0.
