 Name

    XFocusChangeEvent - FocusIn and FocusOut event structure

 Structures

    The structure for FocusIn and FocusOut events contains:

    typedef struct {
        int type;              /* FocusIn or FocusOut */
        unsigned long serial;  /* # of last request processed by server */
        Bool send_event;       /* true if this came from a SendEvent request */
        Display *display;      /* Display the event was read from */
        Window window;         /* window of event */
        int mode;              /* NotifyNormal, NotifyGrab, NotifyUngrab */
        int detail;            /* NotifyAncestor, NotifyVirtual, NotifyInferior,
                                * NotifyNonlinear,NotifyNonlinearVirtual,
                                * NotifyPointer, NotifyPointerRoot,
                                * NotifyDetailNone */
    } XFocusChangeEvent;
    typedef XFocusChangeEvent XFocusInEvent;
    typedef XFocusChangeEvent XFocusOutEvent;

    When you receive these events, the structure members are set as follows.

    The type member is set to the event type constant name that uniquely
    identifies it.  For example, when the X server reports a GraphicsExpose
    event to a client application, it sends an XGraphicsExposeEvent structure
    with the type member set to GraphicsExpose.  The display member is set to
    a pointer to the display the event was read on.  The sendevent member is
    set to True if the event came from a SendEvent protocol request.  The
    serial member is set from the serial number reported in the protocol but
    expanded from the 16-bit least-significant bits to a full 32-bit value.
    The window member is set to the window that is most useful to toolkit
    dispatchers.

    The window member is set to the window on which the FocusIn or FocusOut
    event was generated.  This is the window used by the X server to report
    the event.  The mode member is set to indicate whether the focus events
    are normal focus events, focus events while grabbed, focus events when a
    grab activates, or focus events when a grab deactivates.  The X server
    can set the mode member to NotifyNormal, NotifyWhileGrabbed, NotifyGrab,
    or NotifyUngrab.

    All FocusOut events caused by a window unmap are generated after any
    UnmapNotify event; however, the X protocol does not constrain the order-
    ing of FocusOut events with respect to generated EnterNotify, LeaveNo-
    tify, VisibilityNotify, and Expose events.

    Depending on the event mode, the detail member is set to indicate the
    notify detail and can be NotifyAncestor, NotifyVirtual, NotifyInferior,
    NotifyNonlinear, NotifyNonlinearVirtual, NotifyPointer, NotifyPointer-
    Root, or NotifyDetailNone.
