XISETFOCUS(3)							 XISETFOCUS(3)

NAME
       XISetFocus, XIGetFocus -	set or get the device's	focus.

SYNOPSIS
       #include	<X11/extensions/XInput2.h>

       Status XISetFocus( Display *display,
			  int deviceid,
			  Window focus,
			  Time time);

       Status XIGetFocus( Display *display,
			  Window *focus_return);

       display
	      Specifies	the connection to the X	server.

       deviceid
	      Specifies	the device whose focus is to be	queried	or
	      changed.

       focus
	      The new focus window.

       focus_return
	      Returns the current focus	window.

       time
	      A	valid timestamp	or CurrentTime.

DESCRIPTION
	   XISetFocus changes the focus	of the specified device	ans its
	   last-focus-change time. It has no effect if the specified time
	   is earlier than the current last-focus-change time or is later
	   than	the current X server time. Otherwise, the
	   last-focus-change time is set to the	specified time.
	   CurrentTime is replaced by the current X server time).
	   XISetFocus causes the X server to generate core, XI and XI2
	   focus events.

	   If the focus	window is None all keyboard events by this device
	   are discarded until a new focus window is set. Otherwise, if
	   focus is a window, it becomes the device's focus window. If a
	   generated device event would	normally be reported to	this
	   window or one of its	inferiors, the event is	reported as usual.
	   Otherwise, the event	is reported relative to	the focus window.

	   The specified focus window must be viewable at the time
	   XISetFocus is called, or a BadMatch error results. If the focus
	   window later	becomes	not viewable, the focus	reverts	to the
	   parent (or the closest viewable ancestor. When the focus
	   reverts, the	X server generates core, XI and	XI2 focus events
	   but the last-focus-change time is not affected.

	   Attempting to set the focus on a master pointer device or an
	   attached slave device will result in	a BadDevice error.

	   XISetFocus can generate BadDevice, BadMatch,	BadValue, and
	   BadWindow errors.

DIAGNOSTICS
	   BadValue
		  A value is outside of	the permitted range.

	   BadDevice
		  An invalid device was	specified. The device does not
		  exist	or is not a appropriate	for the	type of	change.

	   BadMatch
		  The window is	not viewable.

	   BadWindow
		  A value for a	Window argument	does not name a	defined
		  Window.
