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\&.

The XGetDeviceButtonMapping request returns the current mapping

one\&.XGetDeviceButtonMapping returns the number of physical

buttons actually on the device\&. The nominal mapping for a

the array where the device mapping is returned, and only the
