NAME

STRUCTURES

9       The structure for FocusIn and FocusOut events contains:
10
11       typedef struct {
12               int type;       /* FocusIn or FocusOut */
13               unsigned long serial;   /* # of last request processed by server */
14               Bool send_event;        /* true if this came from a SendEvent request */
15               Display *display;       /* Display the event was read from */
16               Window window;  /* window of event */
17               int mode;       /* NotifyNormal, NotifyGrab, NotifyUngrab */
18               int detail;
19                       /*
20                       * NotifyAncestor, NotifyVirtual, NotifyInferior,
21                       * NotifyNonlinear,NotifyNonlinearVirtual, NotifyPointer,
22                       * NotifyPointerRoot, NotifyDetailNone
23                       */
24       } XFocusChangeEvent;
25       typedef XFocusChangeEvent XFocusInEvent;
26       typedef XFocusChangeEvent XFocusOutEvent;
27
28       When  you  receive  these events, the structure members are set as fol‐
29       lows.
30
31       The type member is set to the event type constant  name  that  uniquely
32       identifies it.  For example, when the X server reports a GraphicsExpose
33       event to a client application, it sends an XGraphicsExposeEvent  struc‐
34       ture with the type member set to GraphicsExpose.  The display member is
35       set to a pointer to the display the event was read on.  The  send_event
36       member  is  set to True if the event came from a SendEvent protocol re‐
37       quest.  The serial member is set from the serial number reported in the
38       protocol  but expanded from the 16-bit least-significant bits to a full
39       32-bit value.  The window member is set to the window that is most use‐
40       ful to toolkit dispatchers.
41
42       The window member is set to the window on which the FocusIn or FocusOut
43       event was generated.  This is the window used by the X server to report
44       the event.  The mode member is set to indicate whether the focus events
45       are normal focus events, focus events while grabbed, focus events  when
46       a  grab  activates,  or  focus  events  when a grab deactivates.  The X
47       server can set the mode member to NotifyNormal, NotifyWhileGrabbed, No‐
48       tifyGrab, or NotifyUngrab.
49
50       All  FocusOut  events  caused by a window unmap are generated after any
51       UnmapNotify event; however, the X protocol does not constrain  the  or‐
52       dering  of  FocusOut  events  with  respect  to  generated EnterNotify,
53       LeaveNotify, VisibilityNotify, and Expose events.
54
55       Depending on the event mode, the detail member is set to  indicate  the
56       notify detail and can be NotifyAncestor, NotifyVirtual, NotifyInferior,
57       NotifyNonlinear, NotifyNonlinearVirtual, NotifyPointer,  NotifyPointer‐
58       Root, or NotifyDetailNone.
