SYNOPSIS
|
||
|
|
--------

Status XChangePointerDevice( Display *display,
|
||
|
|
XDevice *device,
|
||
|
|
int xaxis,
|
||
|
|
int yaxis);
|
||
|
|
|
||
|
|
display
|
||
|
|
Specifies the connection to the X server.
|
||
|
|
|
||
|
|
device
|
||
|
|
Specifies the device to be used as the X pointer.
|
||
|
|
|
||
|
|
xaxis
|
||
|
|
Specifies the axis of the device to be used as the X
|
||
|
|
pointer x-axis.
|
||
|
|
|
||
|
|
yaxis
|
||
|
|
Specifies the axis of the device to be used as the X
|
||
|
|
pointer y-axis.
|

|
|
|
||
|
|
DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The XChangePointerDevice request causes the server to use the
|
||
|
|
specified device as the X pointer. The device must have been
|
||
|
|
opened by the client via XOpenDevice or a BadDevice error will
|
||
|
|
result. The device must support input class Valuators or a
|
||
|
|
BadMatch error will result. If the implementation does not
|
||
|
|
support use of the specified device as the X pointer, a
|
||
|
|
BadDevice error will result.
|
||
|
|
|
||
|
|
If the specified device is grabbed by another client,
|
||
|
|
AlreadyGrabbed is returned. If the specified device is frozen
|
||
|
|
by a grab on another device, GrabFrozen is returned. If the
|
||
|
|
request is successful, Success is returned.
|
||
|
|
|
||
|
|
If the request succeeds, a ChangeDeviceNotify event is sent to
|
||
|
|
all clients that have selected that event. A MappingNotify
|
||
|
|
event with request = MappingPointer is sent to all clients. The
|
||
|
|
specified device becomes the X pointer, and the old X pointer
|
||
|
|
becomes accessible through the input extension protocol
|
||
|
|
requests.
|
||
|
|
|
||
|
|
XChangePointerDevice can generate a BadDevice or a BadMatch
|
||
|
|
error.
|
||
|
|
|
||
|
|
DIAGNOSTICS
|
||
|
|
-----------
|
||
|
|
|
||
|
|
BadDevice
|
||
|
|
An invalid device was specified. The specified device
|
||
|
|
does not exist, has not been opened by this client via
|
||
|
|
XOpenInputDevice, or is already one of the core X input
|
||
|
|
devices (pointer or keyboard). This error may also occur
|
||
|
|
if the server implementation does not support using the
|
||
|
|
specified device as the X pointer.
|
||
|
|
|
||
|
|
BadMatch
|
||
|
|
This error may occur if an XChangePointerDevice request
|
||
|
|
was made specifying a device that has less than two
|
||
|
|
valuators, or specifying a valuator index beyond the
|
||
|
|
range supported by the device.
