SDL Wiki


A hint that specifies the address of another SDL_Window* (as a hex string formatted with "%p").



the address (as a string "%p") of the SDL_Window* that new windows created with SDL_CreateWindowFrom() should share a pixel format with


By default this hint is not set.


If this hint is set before SDL_CreateWindowFrom() and the SDL_Window* it is set to has SDL_WINDOW_OPENGL set (and running on WGL only, currently), then two things will occur on the newly created SDL_Window:

1. Its pixel format will be set to the same pixel format as this SDL_Window.  This is needed for example when sharing an OpenGL context across multiple windows.

1. The flag SDL_WINDOW_OPENGL will be set on the new window so it can be used for OpenGL rendering.


This hint is available since SDL 2.0.2.
