Clients can send events to each others. Most often these are
ClientMessage events, but any event type can be
To send an event, an event object must be created. This is done by
instantiating an event class, providing values to all its fields as
keyword parameters. The event is then sent with the
Send event to this window.
If event_mask is 0, the event is sent to the client that created the window. Otherwise the event is sent to every client selecting any of the event types in event_mask.
If no clients have selected any of the event types and propagate is true, the X server will search for an ancestor of this window on which some client has selected any of the event types. For details, see XSendEvent(3X11).
Send event to destination, which can either be a
Window object or a constant: If
specified, send the event to the window the pointer is in. If
X.InputFocus is specified and the focus window contains the
pointer, send the event to the window that the pointer is in.
Otherwise, send the event to the focus window.
As an example, this creates and sends a
ClientMessage event of
the client specific type
HELLO_WORLD (an atom), to the window
dest and with the 8-bitformat value
"G'day, mate" (which
must be exactly twenty bytes):
cm_event = Xlib.protocol.event.ClientMessage( window = dest, client_type = HELLO_WORLD, data = (8, "G'day mate\0\0\0\0\0\0\0\0\0\0")) dest.send_event(cm_event)
