typedef void* SDL_MetalView |
A handle to a CAMetalLayer-backed NSView (macOS) or UIView (iOS/tvOS).
Definition at line 44 of file SDL_metal.h.
SDL_MetalView SDL_Metal_CreateView | ( | SDL_Window * | window | ) |
Create a CAMetalLayer-backed NSView/UIView and attach it to the specified window.
On macOS, this does not associate a MTLDevice with the CAMetalLayer on its own. It is up to user code to do that.
The returned handle can be casted directly to a NSView or UIView. To access the backing CAMetalLayer, call SDL_Metal_GetLayer().
void SDL_Metal_DestroyView | ( | SDL_MetalView | view | ) |
Destroy an existing SDL_MetalView object.
This should be called before SDL_DestroyWindow, if SDL_Metal_CreateView was called after SDL_CreateWindow.
void SDL_Metal_GetDrawableSize | ( | SDL_Window * | window, |
int * | w, | ||
int * | h | ||
) |
Get the size of a window's underlying drawable in pixels (for use with setting viewport, scissor & etc).
window | SDL_Window from which the drawable size should be queried |
w | Pointer to variable for storing the width in pixels, may be NULL |
void* SDL_Metal_GetLayer | ( | SDL_MetalView | view | ) |
Get a pointer to the backing CAMetalLayer for the given view.
