       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, NotifyNonlinearVirtual, NotifyPointer,
       NotifyPointerRoot, or NotifyDetailNone.
