XWarpPointer(3X11) X Version 11 (Release 5) XWarpPointer(3X11)
NAME
XWarpPointer - move pointer
SYNTAX
XWarpPointer(display, src_w, dest_w, src_x, src_y,
src_width, src_height, dest_x,
dest_y)
Display *display;
Window src_w, dest_w;
int src_x, src_y;
unsigned int src_width, src_height;
int dest_x, dest_y;
ARGUMENTS
dest_w Specifies the destination window or None.
dest_x
dest_y Specify the x and y coordinates within the
destination window.
display Specifies the connection to the X server.
src_x
src_y
src_width
src_height
Specify a rectangle in the source window.
src_w Specifies the source window or None.
DESCRIPTION
If dest_w is None, XWarpPointer moves the pointer by the
offsets (dest_x, dest_y) relative to the current position of
the pointer. If dest_w is a window, XWarpPointer moves the
pointer to the offsets (dest_x, dest_y) relative to the
origin of dest_w. However, if src_w is a window, the move
only takes place if the window src_w contains the pointer
and if the specified rectangle of src_w contains the
pointer.
The src_x and src_y coordinates are relative to the origin
of src_w. If src_height is zero, it is replaced with the
current height of src_w minus src_y. If src_width is zero,
it is replaced with the current width of src_w minus src_x.
There is seldom any reason for calling this function. The
pointer should normally be left to the user. If you do use
this function, however, it generates events just as if the
user had instantaneously moved the pointer from one position
to another. Note that you cannot use XWarpPointer to move
the pointer outside the confine_to window of an active
pointer grab. An attempt to do so will only move the

pointer as far as the closest edge of the confine_to window.
XWarpPointer can generate a BadWindow error.
DIAGNOSTICS
BadWindow A value for a Window argument does not name a
defined Window.
