Struct SetInputFocusRequest

pub struct SetInputFocusRequest {
    pub revert_to: InputFocus,
    pub focus: u32,
    pub time: u32,
}

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.

Fields

• 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.

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

Errors

• Window - The specified focus window does not exist.
• Match - The specified focus window is not viewable.
• Value - TODO: Reasons?
