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.
