This request requires you to pass an event class list\&. For a discussion of the valid event class names, see XOpenDevice(3) 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\&. .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf 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\&. .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf The event in the XEventstructure must be one of the events defined by the input extension (or a BadValueerror results) so that the X server can correctly byte\-swapthe contents as necessary\&.
