NAME¶
XkbSetDeviceButtonActions - Change only the button actions for an input
extension device
SYNOPSIS¶
Bool XkbSetDeviceButtonActions (Display
*dpy, XkbDeviceInfoPtr device,
unsigned int first_button, unsigned int
num_buttons);
ARGUMENTS¶
- - dpy
- connection to X server
- - device
- structure defining the device and modifications
- - first_button
- number of first button to update, 0 relative
- - num_buttons
- number of buttons to update
DESCRIPTION¶
XkbSetDeviceButtonActions assigns actions to the buttons of the device
specified in
device_info->device_spec. Actions are assigned to
num_buttons buttons beginning with
first_button and are taken
from the actions specified in
device_info->btn_acts.
If the server does not support assignment of Xkb actions to extension device
buttons,
XkbSetDeviceButtonActions has no effect and returns False. If
the device has no buttons or if
first_button or
num_buttons
specify buttons outside of the valid range as determined by
device_info->num_btns, the function has no effect and returns False.
Otherwise,
XkbSetDeviceButtonActions sends a request to the server to
change the actions for the specified buttons and returns True.
If the actual request sent to the server involved illegal button numbers, a
BadValue protocol error is generated. If an invalid device identifier is
specified in
device_info->device_spec, a BadKeyboard protocol error
results. If the actual device specified in
device_info->device_spec
does not contain buttons and a request affecting buttons is made, a BadMatch
protocol error is generated.
DIAGNOSTICS¶
- BadKeyboard
- The device specified was not a valid core or input extension device
- BadMatch
- A compatible version of Xkb was not available in the server or an argument
has correct type and range, but is otherwise invalid
- BadValue
- An argument is out of range
