Function xcb::xproto::set_input_focus

pub fn set_input_focus<'a>(
    c: &'a Connection, 
    revert_to: u8, 
    focus: Window, 
    time: Timestamp
) -> VoidCookie<'a>

Sets input focus

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

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

parameters:

• c: The connection object to the server

• revert_to: 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_error_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.
