DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The ClientPointer is the device that is percieved to be the
|
||
|
|
core pointer for non-XI protocol requests and replies. Each
|
||
|
|
time a protocol message needs device-dependent data and the
|
||
|
|
device is not explicitly given, the ClientPointer device is
|
||
|
|
used to obtain the data. For example, a XQueryPointer request
|
||
|
|
will return the coordinates of the ClientPointer.
|
||
|
|
|
||
|
|
XISetClientPointer request sets the ClientPointer device for
|
||
|
|
the client that owns the given window. If win is None, the
|
||
|
|
requesting client's ClientPointer is set to the device
|
||
|
|
specified with deviceid. Only master pointer devices can be set
|
||
|
|
as ClientPointer.
|
||
|
|
|
||
|
|
XISetClientPointer and can generate a BadDevice and a BadWindow
|
||
|
|
error.
|
||
|
|
|
||
|
|
The XIGetClientPointer request returns the ClientPointer's
|
||
|
|
device ID for the client that owns the given window. If win is
|
||
|
|
None, the requesting client's ClientPointer is returned.
|
||
|
|
|
||
|
|
win may be a client ID instead of a window.
|
||
|
|
|
||
|
|
XIGetClientPointer can generate a BadWindow error.
