xcb_set_input_focus(3)						   XCB Requests 					    xcb_set_input_focus(3)

NAME

       xcb_set_input_focus - Sets input focus

SYNOPSIS

       #include <xcb/xproto.h>

   Request function
       xcb_void_cookie_t xcb_set_input_focus(xcb_connection_t *conn, uint8_t revert_to, xcb_window_t focus, xcb_timestamp_t time);

REQUEST ARGUMENTS

       conn	 The XCB connection to X11.

       revert_to One of the following values:

		 XCB_INPUT_FOCUS_NONE
			   The focus reverts to XCB_NONE, so no window will have the input focus.

		 XCB_INPUT_FOCUS_POINTER_ROOT
			   The focus reverts to XCB_POINTER_ROOT respectively. When the focus reverts, FocusIn and FocusOut events are generated,
			   but the last-focus-change time is not changed.

		 XCB_INPUT_FOCUS_PARENT
			   The focus reverts to the parent (or closest viewable ancestor) and the new revert_to value is XCB_INPUT_FOCUS_NONE.

		 XCB_INPUT_FOCUS_FOLLOW_KEYBOARD
			   NOT YET DOCUMENTED. Only relevant for the xinput extension.

		 Specifies what happens when the focus window becomes unviewable (if focus is neither XCB_NONE nor XCB_POINTER_ROOT).

       focus	 The window to focus. All keyboard events will be reported to this window. The window must be viewable (TODO), or a xcb_match_er-
		 ror_t occurs (TODO).

		 If focus is XCB_NONE (TODO), all keyboard events are discarded until a new focus window is set.

		 If focus is XCB_POINTER_ROOT (TODO), focus is on the root window of the screen on which the pointer is on currently.

       time	 Timestamp to avoid race conditions when running X over the network.

		 The special value XCB_CURRENT_TIME will be replaced with the current server time.

DESCRIPTION

       Changes the input focus and the last-focus-change time. If the specified time is earlier than the current last-focus-change time, the re-
       quest is ignored (to avoid race conditions when running X over the network).

       A FocusIn and FocusOut event is generated when focus is changed.

RETURN VALUE

       Returns an xcb_void_cookie_t. Errors (if any) have to be handled in the event loop.

       If you want to handle errors directly with xcb_request_check instead, use xcb_set_input_focus_checked. See xcb-requests(3) for details.

ERRORS

       xcb_window_error_t
		 The specified focus window does not exist.

       xcb_value_error_t
		 TODO: Reasons?

       xcb_match_error_t
		 The specified focus window is not viewable.

REQUEST ARGUMENTS

       conn	 The XCB connection to X11.

REPLY FIELDS

       response_type
		 The type of this reply, in this case XCB_GET_INPUT_FOCUS. This field is also present in the xcb_generic_reply_t and can be used
		 to tell replies apart from each other.

       sequence  The sequence number of the last request processed by the X11 server.

       length	 The length of the reply, in words (a word is 4 bytes).

       revert_to One of the following values:

		 XCB_INPUT_FOCUS_NONE
			   The focus reverts to XCB_NONE, so no window will have the input focus.

		 XCB_INPUT_FOCUS_POINTER_ROOT
			   The focus reverts to XCB_POINTER_ROOT respectively. When the focus reverts, FocusIn and FocusOut events are generated,
			   but the last-focus-change time is not changed.

		 XCB_INPUT_FOCUS_PARENT

		 XCB_INPUT_FOCUS_FOLLOW_KEYBOARD
			   NOT YET DOCUMENTED. Only relevant for the xinput extension.
		 TODO: NOT YET DOCUMENTED.

       focus	 TODO: NOT YET DOCUMENTED.

DESCRIPTION

RETURN VALUE

       Returns an xcb_get_input_focus_cookie_t. Errors have to be handled when calling the reply function xcb_get_input_focus_reply.

       If you want to handle errors in the event loop instead, use xcb_get_input_focus_unchecked. See xcb-requests(3) for details.

ERRORS

       This request does never generate any errors.
