NAME
XSetDeviceButtonMapping, XGetDeviceButtonMapping − query or change device button mappings
SYNOPSIS
#include <X11/extensions/XInput.h>
int
XSetDeviceButtonMapping( Display *display,
XDevice *device,
unsigned char map[],
int nmap);
int
XGetDeviceButtonMapping( Display *display,
XDevice *device,
unsigned char map_return[],
int nmap);
display
Specifies the connection to the X server.
device
Specifies the device whose button mapping is to be
queried or changed.
map
Specifies the mapping list.
map_return
Returns the mapping list.
nmap
Specifies the number of items in the mapping list.
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.
