XkbSetDeviceButtonActions(3) XKB FUNCTIONS XkbSetDeviceButtonActions(3)NAME
XkbSetDeviceButtonActions - Change only the button actions for an input extension device
SYNTAX
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

XkbChangeDeviceInfo(3) XKB FUNCTIONS XkbChangeDeviceInfo(3)NAME
XkbChangeDeviceInfo - Update the server's description of a device with the changes noted in an XkbDeviceChangesRec
SYNOPSIS
Bool XkbChangeDeviceInfo (Display *dpy, XkbDeviceInfoPtr device_info, XkbDeviceChangesPtr changes);
ARGUMENTS
- dpy connection to X server
- device_info
local copy of device state and configuration
- changes
note specifying changes in device_info
DESCRIPTION
XkbChangeDeviceInfo updates the server's description of the device specified in device_info->device_spec with the changes specified in
changes and contained in device_info. The update is made by an XkbSetDeviceInfo request.
STRUCTURES
Changes to an Xkb extension device may be tracked by listening to XkbDeviceExtensionNotify events and accumulating the changes in an XkbDe-
viceChangesRec structure. The changes noted in the structure may then be used in subsequent operations to update either a server configura-
tion or a local copy of an Xkb extension device configuration. The changes structure is defined as follows:
typedef struct _XkbDeviceChanges {
unsigned int changed; /* bits indicating what has changed */
unsigned short first_btn; /* number of first button which changed, if any */
unsigned short num_btns; /* number of buttons that have changed */
XkbDeviceLedChangesRec leds;
} XkbDeviceChangesRec,*XkbDeviceChangesPtr;
