DESCRIPTION
|
||
|
|
-----------
|
||
|
|
|
||
|
|
The XSetDeviceButtonMapping request sets the mapping of the
|
||
|
|
specified device. If it succeeds, the X server generates a
|
||
|
|
DeviceMappingNotify event, and XSetDeviceButtonMapping returns
|
||
|
|
MappingSuccess. Element map[i] defines the logical button
|
||
|
|
number for the physical button i+1. The length of the list must
|
||
|
|
be the same as XGetDeviceButtonMapping would return, or a
|
||
|
|
BadValue error results. A zero element disables a button, and
|
||
|
|
elements are not restricted in value by the number of physical
|
||
|
|
buttons. However, no two elements can have the same nonzero
|
||
|
|
value, or a BadValue error results. If any of the buttons to be
|
||
|
|
altered are logically in the down state,
|
||
|
|
XSetDeviceButtonMapping returns MappingBusy, and the mapping is
|
||
|
|
not changed.
|
||
|
|
|
||
|
|
XSetDeviceButtonMapping can generate BadDevice, BadMatch, and
|
||
|
|
BadValue errors.
|
||
|
|
|
||
|
|
The XGetDeviceButtonMapping request returns the current mapping
|
||
|
|
of the specified device. Buttons are numbered starting from
|
||
|
|
one.XGetDeviceButtonMapping returns the number of physical
|
||
|
|
buttons actually on the device. The nominal mapping for a
|
||
|
|
device is map[i]=i+1. The nmap argument specifies the length of
|
||
|
|
the array where the device mapping is returned, and only the
|
||
|
|
first nmap elements are returned in map_return.
|
||
|
|
|
||
|
|
XGetDeviceButtonMapping can generate BadDevice or BadMatch
|
||
|
|
errors.

DIAGNOSTICS
|
||
|
|
-----------
|
||
|
|
|
||
|
|
BadDevice
|
||
|
|
An invalid device was specified. The specified device
|
||
|
|
does not exist or has not been opened by this client via
|
||
|
|
XOpenInputDevice. This error may also occur if the
|
||
|
|
specified device is the X keyboard or X pointer device.
|
||
|
|
|
||
|
|
BadMatch
|
||
|
|
This error may occur if an XGetDeviceButtonMapping or
|
||
|
|
XSetDeviceButtonMapping request was made specifying a
|
||
|
|
device that has no buttons.
|
||
|
|
|
||
|
|
BadValue
|
||
|
|
Some numeric value falls outside the range of values
|
||
|
|
accepted by the request. Unless a specific range is
|
||
|
|
specified for an argument, the full range defined by the
|
||
|
|
argument's type is accepted. Any argument defined as a
|
||
|
|
set of alternatives can generate this error.
