NAME

SDL_GetGlobalMouseState - Query the platform for the asynchronous mouse button state and the desktop-relative platform-cursor position.

HEADER FILE

Defined in SDL3/SDL_mouse.h

SYNOPSIS

#include "SDL3/SDL.h"

SDL_MouseButtonFlags SDL_GetGlobalMouseState(float *x, float *y);

DESCRIPTION

This function immediately queries the platform for the most recent asynchronous state, more costly than retrieving SDL’s cached state in

SDL_GetMouseState ().

Passing non-NULL pointers to x or y will write the destination with respective x or y coordinates relative to the desktop.

In Relative Mode, the platform-cursor’s position usually contradicts the SDL-cursor’s position as manually calculated from

SDL_GetMouseState () and

SDL_GetWindowPosition .

This function can be useful if you need to track the mouse outside of a specific window and SDL_CaptureMouse () doesn’t fit your needs. For example, it could be useful if you need to track the mouse while dragging a window, where coordinates relative to a window might not be in sync at all times.

FUNCTION PARAMETERS

	x		a pointer to receive the platform-cursor’s x-position from the desktop’s top left corner, can be NULL if unused.
	y		a pointer to receive the platform-cursor’s y-position from the desktop’s top left corner, can be NULL if unused.

RETURN VALUE

( SDL_MouseButtonFlags ) Returns a 32-bit bitmask of the button state that can be bitwise-compared against the

SDL_BUTTON_MASK (X) macro.

THREAD SAFETY

This function should only be called on the main thread.

AVAILABILITY

This function is available since SDL 3.2.0.
