sdlxGetWindowSize function video

({int h, int w})? sdlxGetWindowSize(Pointer<SdlWindow> window)

Get the size of a window's client area.

The window pixel size may differ from its window coordinate size if the window is on a high pixel density display. Use SDL_GetWindowSizeInPixels() or SDL_GetRenderOutputSize() to get the real client area size in pixels.

\param window the window to query the width and height from. \param w a pointer filled in with the width of the window, may be NULL. \param h a pointer filled in with the height of the window, may be NULL. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.
