XIWarpPointer

NAME

XIWarpPointer - move a device's pointer.

SYNOPSIS

 #include <X11/extensions/XInput2.h>
 

 Bool XIWarpPointer( Display *display,
                     int deviceid,
                     Window src_w,
                     Window dest_w,
                     double src_x,
                     double src_y,
                     int src_width,
                     int src_height,
                     double dest_x,
                     double dest_y);
 

 dest_w
        Specifies the destination window or None.
 

 dest_x, dest_y
        Specify the x and y coordinates within the destination
        window.
 

 deviceid
        Specifies the master pointer device or floating slave
        device to move.
 

 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, XIWarpPointer moves the pointer by the
 offsets (dest_x, dest_y) relative to the current position of
 the pointer. If dest_w is a window, XIWarpPointer 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 XIWarpPointer 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.
 

 XIWarpPointer is identical to XWarpPointer but specifies the
 device explicitly.
 

 XIWarpPointer can generate a BadDevice and a BadWindow error.
 

DIAGNOSTICS

 BadDevice
        An invalid device was specified. The device does not
        exist or is not a pointer device.
 

 BadWindow
        A value for a Window argument does not name a defined
        window.
