When the user moves the mouse, the system moves a bitmap on the screen called
the mouse cursor
. The mouse cursor contains a single-pixel point called the hot spot
, a point that the system tracks and recognizes as the position of the cursor.
When a mouse event occurs, the window that contains the hot spot typically
receives the mouse message resulting from the event. The window need not be active
or have the keyboard focus to receive a mouse message.
The system maintains a variable that controls the mouse speed
that is, the distance the cursor moves when the user moves the mouse. You can
use the SystemParametersInfo
function with the SPI_GETMOUSE or SPI_SETMOUSE flag to retrieve or set the
mouse speed. For more information about mouse cursors, see Cursors
