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_but-
tons 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 de-
vice_info->num_btns, the function has no effect and returns False. Oth-
erwise, 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 num-
bers, a BadValue protocol error is generated. If an invalid device iden-
tifier is specified in device_info->device_spec, a BadKeyboard protocol
error results. If the actual device specified in device_info->de-
vice_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 exten-
sion 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
