If a cursor is set, it will be used when the device's pointer
|

is in the window. If the cursor is None, it is equivalent to
|
|
XIUndefineCursor.

The XIUndefineCursor function undoes the effect of a previous
|
|
XIDefineCursor for this window. When the pointer is in the
|
|
window, the window's default cursor will now be used. If no
|
|
default cursor is defined, the parent's cursor for this device
|
|
will be used (if defined) or the parent's default cursor will
|
|
be used.
