SwapMouseButton function

Reverses or restores the meaning of the left and right mouse buttons.

Syntax


BOOL WINAPI SwapMouseButton(
  _In_  BOOL fSwap
);

Parameters

fSwap [in]

Type: BOOL

If this parameter is TRUE, the left button generates right-button messages and the right button generates left-button messages. If this parameter is FALSE, the buttons are restored to their original meanings.

Return value

Type: BOOL

If the meaning of the mouse buttons was reversed previously, before the function was called, the return value is nonzero.

If the meaning of the mouse buttons was not reversed, the return value is zero.

Remarks

Button swapping is provided as a convenience to people who use the mouse with their left hands. The SwapMouseButton function is usually called by Control Panel only. Although an application is free to call the function, the mouse is a shared resource and reversing the meaning of its buttons affects all applications.
