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 and 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.
