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
     send_event 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 ordering of FocusOut events with respect
     to generated EnterNotify, LeaveNotify, 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, NotifyNon-
     linearVirtual, NotifyPointer, NotifyPointerRoot, or
     NotifyDetailNone.
