NAME

XkbGetDeviceButtonActions - Query the button actions associated with an X Input Extension device  

SYNOPSIS

Status XkbGetDeviceButtonActions (Display *dpy, XkbDeviceInfoPtr device_info, Bool all_buttons, unsigned int first_button, unsigned int num_buttons);
     

 

ARGUMENTS

- dpy

connection to X server

- device_info

structure to update with results

- all_buttons

True => get information for all buttons

- first_button

number of first button for which info is desired

- num_buttons

number of buttons for which info is desired

 

DESCRIPTION

XkbGetDeviceButtonActions queries the server for the desired button information for the device indicated by the device_spec field of device_info and waits for a reply. If successful, XkbGetDeviceButtonActions backfills the button actions (btn_acts field of device_info) for only the requested buttons, updates the name, type, supported, and unsupported fields, and returns Success.

all_buttons, first_button and num_buttons specify the device buttons for which actions should be returned. Setting all_buttons to True requests actions for all device buttons; if all_buttons is False, first_button and num_buttons specify a range of buttons for which actions are requested.

If a compatible version of Xkb is not available in the server or the Xkb extension has not been properly initialized, XkbGetDeviceButtonActions returns BadAccess. If allocation errors occur, a BadAlloc status is returned. If the specified device (device_info->device_spec) is invalid, a BadKeyboard status is returned. If the device has no buttons, a BadMatch status is returned. If first_button and num_buttons specify illegal buttons, a BadValue status is returned.  

DIAGNOSTICS

BadAlloc

BadKeyboard

The device specified was not a valid core or input extension device
