Typedef Documentation

◆ SDL_MetalView

typedef void* SDL_MetalView

A handle to a CAMetalLayer-backed NSView (macOS) or UIView (iOS/tvOS).

Note
This can be cast directly to an NSView or UIView.

Definition at line 44 of file SDL_metal.h.

Function Documentation

◆ SDL_Metal_CreateView()

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().

◆ SDL_Metal_DestroyView()

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.
