1 XSENDEXTENSIONEVENT(libmansuffix)
2 =================================
7 XSendExtensionEvent - send input extension events to a client
12 #include <X11/extensions/XInput.h>
14 Status XSendExtensionEvent( Display *display,
19 XEventClass *event_list,
23 Specifies the connection to the X server.
26 Specifies the device from which the events are to be
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.
37 Specifies the count of XEventClasses in event_list.
40 Specifies the list of event selections to be used.
43 Specifies a pointer to the event that is to be sent.
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
55 * If w is PointerWindow,the destination window is the window
56 that contains the pointer.
57 * If w is InputFocusand 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
62 To determine which clients should receive the specified events,
63 XSendExtensionEventuses 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 eventtypes specified by
70 * If propagate is Trueand no clients have selected on
71 destination any ofthe events specified by the event_list
72 array,the destination is replaced with theclosest ancestor
73 of destination for which some client has selected atype
74 specified by the event-list array and for which no
75 interveningwindow has that type in
76 itsdo-not-propagate-mask. If no such window exists or if
77 the window isan ancestor of the focus window and
78 InputFocuswas originally specifiedas the destination, the
79 event is not sent to any clients. Otherwise, the event is
80 reported to every client selecting on the finaldestination
81 any of the events specified in the event_list array.
83 The event in the XEventstructure must be one of the events
84 defined by the input extension (or a BadValueerror results) so
85 that the X server can correctly byte-swapthe contents as
86 necessary. The contents of the event areotherwise unaltered and
87 unchecked by the X server except to force send_event to Truein
88 the forwarded event and to set the serial number in the event
91 XSendExtensionEventreturns zero if the conversion to wire
92 protocol format failedand returns nonzero
93 otherwise.XSendExtensionEventcan generate BadClass, BadDevice,
94 BadValue, and BadWindow errors.
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.
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.
