21   
22   display
23          Specifies the connection to the X server.
24
25   device
26          Specifies the device from which the events are to be
27          sent.
28
29   destination
30          Specifies the window the event is to be sent to. You can
31          pass window id, PointerWindow, or InputFocus.

34          Specifies a Boolean value that is either True or False.

36   event_count
37          Specifies the count of XEventClasses in event_list.
38
39   event_list
40          Specifies the list of event selections to be used.
41
42   event_send
43          Specifies a pointer to the event that is to be sent.

45DESCRIPTION
46-----------
47
48   The XSendExtensionEvent request identifies the destination
49   window, determines which clients should receive the specified
50   events, and ignores any active grabs. This request requires you
51   to pass an event class list. For a discussion of the valid
52   event class names, see XOpenDevice(libmansuffix) This
53   request uses the w argument to identify the destination window
54   as follows:
55     * If w is PointerWindow, the destination window is the window
56       that contains the pointer.
57     * If w is InputFocus and if the focus window contains the
58       pointer, the destination window is the window that contains
59       the pointer; otherwise, the destination window is the focus
60       window.
61
62   To determine which clients should receive the specified events,
63   XSendExtensionEvent uses the propagate argument as follows:
64     * If event_list is the empty set, the event is sent to the
65       client that created the destination window. If that client
66       no longer exists, no event is sent.
67     * If propagate is False, the event is sent to every client
68       selecting on destination any of the event types specified by
69       the event_list array.
70     * If propagate is True and no clients have selected on
71       destination any of the events specified by the event_list
72       array, the destination is replaced with the closest ancestor
73       of destination for which some client has selected a type
74       specified by the event-list array and for which no
75       intervening window has that type in
76       its do-not-propagate-mask. If no such window exists or if
77       the window is an ancestor of the focus window and
78       InputFocus was originally specified as the destination, the
79       event is not sent to any clients. Otherwise, the event is
80       reported to every client selecting on the final destination
81       any of the events specified in the event_list array.
82
83   The event in the XEvent structure must be one of the events
84   defined by the input extension (or a BadValue error results) so
85   that the X server can correctly byte-swap the contents as
86   necessary. The contents of the event are otherwise unaltered and
87   unchecked by the X server except to force send_event to True in
88   the forwarded event and to set the serial number in the event
89   correctly.
90
91   XSendExtensionEvent returns zero if the conversion to wire
92   protocol format failed and returns nonzero
93   otherwise. XSendExtensionEvent can generate BadClass, BadDevice,
94   BadValue, and BadWindow errors.

96DIAGNOSTICS
97-----------
98
99   BadDevice
100          An invalid device was specified. The specified device
101          does not exist or has not been opened by this client via
102          XOpenInputDevice. This error may also occur if the
103          specified device is the X keyboard or X pointer device.
104
105   BadValue
106          Some numeric value falls outside the range of values
107          accepted by the request. Unless a specific range is
108          specified for an argument, the full range defined by the
109          argument's type is accepted. Any argument defined as a
110          set of alternatives can generate this error.
111
112   BadWindow
113          A value for a Window argument does not name a defined
114          window.
