The XSendExtensionEvent request identifies the destination
|
|
window, determines which clients should receive the specified
|
|
events, and ignores any active grabs\&. This request requires you
|
|
to pass an event class list\&. For a discussion of the valid
|
|
event class names, see XOpenDevice(libmansuffix) This
|
|
request uses the w argument to identify the destination window
|
|
as follows:
|
|
* If w is PointerWindow,the destination window is the window
|
|
that contains the pointer\&.
|
|
* If w is InputFocusand if the focus window contains the
|
|
pointer,the destination window is the window that contains
|
|
the pointer; otherwise, the destination window is the focus
|
|
window\&.

|
|
To determine which clients should receive the specified events,
|
|
XSendExtensionEventuses the propagate argument as follows:
|
|
* If event_list is the empty set,the event is sent to the
|
|
client that created the destination window\&. If that client
|
|
no longer exists,no event is sent\&.
|
|
* If propagate is False,the event is sent to every client
|
|
selecting on destination any of the eventtypes specified by
|
|
the event_list array\&.
|
|
* If propagate is Trueand no clients have selected on
|
|
destination any ofthe events specified by the event_list
|
|
array,the destination is replaced with theclosest ancestor
|
|
of destination for which some client has selected atype
|
|
specified by the event\-list array and for which no
|
|
interveningwindow has that type in
|
|
itsdo\-not\-propagate\-mask\&. If no such window exists or if
|
|
the window isan ancestor of the focus window and
|
|
InputFocuswas originally specifiedas the destination, the
|
|
event is not sent to any clients\&. Otherwise, the event is
|
|
reported to every client selecting on the finaldestination
|
|
any of the events specified in the event_list array\&.
