XWarpPointer(3) XLIB FUNCTIONS XWarpPointer(3)
XWarpPointer - move pointer
int XWarpPointer(Display *display, Window src_w, Window dest_w, int
src_x, int src_y, unsigned int src_width, unsigned int
src_height, int dest_x, int dest_y);
dest_w Specifies the destination window or None.
dest_y Specify the x and y coordinates within the destination win-
display Specifies the connection to the X server.
Specify a rectangle in the source window.
src_w Specifies the source window or None.
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, how-
ever, 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.
BadWindow A value for a Window argument does not name a defined Window.
