As for the patch itself WineD3D.dll already has similar window resize code.
Do
you know why it doesn't resize the window, and if we can make wined3d do
this
job?
There is IWineD3DDeviceImpl_SetupFullscreenWindow, but that one is not
exported so it can't be called from ddraw as it is.
Calling it from within IWineD3DDevice_SetDisplayMode seems troublesome since
the hwnd to use is not always available in the WineD3DDevice. See for
instance this example from CreateSwapChain:
/* Setup hwnd we are using, plus which display this equates to */
object-win_handle = pPresentationParameters-hDeviceWindow;
if (!object-win_handle) {
object-win_handle = This-createParms.hFocusWindow;
}
if(!pPresentationParameters-Windowed object-win_handle) {
IWineD3DDeviceImpl_SetupFullscreenWindow(iface, object-win_handle,
pPresentationParameters-BackBufferWidth,
pPresentationParameters-BackBufferHeight);
