The functions mouse-position
and set-mouse-position
give access to the current position of the mouse.
This function returns a description of the position of the mouse. The value looks like
(
frame x.
y)
, where x and y are integers giving the position in characters relative to the top left corner of the inside of frame.
If non-
nil
, the value of this variable is a function formouse-position
to call.mouse-position
calls this function just before returning, with its normal return value as the sole argument, and it returns whatever this function returns to it.This abnormal hook exists for the benefit of packages like xt-mouse.el that need to do mouse handling at the Lisp level.
This function warps the mouse to position x, y in frame frame. The arguments x and y are integers, giving the position in characters relative to the top left corner of the inside of frame. If frame is not visible, this function does nothing. The return value is not significant.
This function is like
mouse-position
except that it returns coordinates in units of pixels rather than units of characters.
This function warps the mouse like
set-mouse-position
except that x and y are in units of pixels rather than units of characters. These coordinates are not required to be within the frame.If frame is not visible, this function does nothing. The return value is not significant.
This predicate function returns non-
nil
if the mouse pointer displayed on frame is visible; otherwise it returnsnil
. frame omitted ornil
means the selected frame. This is useful whenmake-pointer-invisible
is set tot
: it allows to know if the pointer has been hidden. See Mouse Avoidance.
