XkbSetDeviceButtonActions(3) XKB FUNCTIONS XkbSetDeviceButtonActions(3)

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
