Date: Tue, 19 Oct 2004 23:04:58 -0700 From: "Trevor Scroggins" Subject: [SDL] [PATCH] DirectX and SDL_WINDOWID Hack Hello, all. The IDirectInputDevice2_SetCooperativeLevel call in SDL_dx5events.c expects to be passed a root-level HWND. More often than not, a child window is used with the SDL_WINDOWID hack, causing the IDirectInputDevice2_SetCooperativeLevel call to fail. This is a small patch to SDL_dx5events.c v1.21 that fixes the problem by retrieving a handle to the root-level ancestor of the current SDL_Window and passing that handle to IDirectInputDevice2_SetCooperativeLevel.
