Returns if the window is full screen (Desktop)

◆ getGlobalCursorPosition()

glm::ivec2 NAPAPI nap::SDL::getGlobalCursorPosition ( )

Get the position of the cursor, in relation to the desktop. This works just like getCursorPosition(), but the coordinates will be reported relative to the top-left of the desktop. Current position of the cursor, in relation to the desktop

◆ getGlobalMouseState()

uint32 NAPAPI nap::SDL::getGlobalMouseState	(	int *	x,
		int *	y
	)

Parameters

x	the current x coordinate, relative to the desktop. Can be nullptr
y	the current y coordinate, relative to the desktop. Can be nullptr

Returns: The current button state as a bitmask, which can be tested using the SDL_BUTTON(X) macros.

◆ getMouseState()

uint32 NAPAPI nap::SDL::getMouseState	(	int *	x,
		int *	y
	)

Get the current state of the mouse relative to the focus window.

Parameters

x	the current x coordinate. Can be nullptr
y	the current y coordinate. Can be nullptr

Returns: The current button state as a bitmask, which can be tested using the SDL_BUTTON(X) macros.
