:Parameters:

A bus name (either the unique name or a well-known name)
of the application owning the object. The keyword argument
named_service is a deprecated alias for this.
`object_path` : str
The object path of the desired object
`introspect` : bool

object to find out supported methods and their signatures

the parameters is received.
:Parameters:
`handler_function` : callable
The function to be called. Its positional arguments will
be the arguments of the signal. By default it will receive
no keyword arguments, but see the description of
the optional keyword arguments below.
`signal_name` : str
The signal name; None (the default) matches all names
`dbus_interface` : str
The D-Bus interface name with which to qualify the signal;
None (the default) matches all interface names
`bus_name` : str
A bus name for the sender, which will be resolved to a
unique name if it is not already; None (the default) matches
any sender.
`path` : str
The object path of the object which must have emitted the
signal; None (the default) matches any object path
:Keywords:
`utf8_strings` : bool
If True, the handler function will receive any string
arguments as dbus.UTF8String objects (a subclass of str
guaranteed to be UTF-8). If False (default) it will receive
any string arguments as dbus.String objects (a subclass of
unicode).
`byte_arrays` : bool
If True, the handler function will receive any byte-array
arguments as dbus.ByteArray objects (a subclass of str).
If False (default) it will receive any byte-array
arguments as a dbus.Array of dbus.Byte (subclasses of:
a list of ints).
`sender_keyword` : str
If not None (the default), the handler function will receive
the unique name of the sending endpoint as a keyword
argument with this name.
`destination_keyword` : str
If not None (the default), the handler function will receive
the bus name of the destination (or None if the signal is a
broadcast, as is usual) as a keyword argument with this name.
`interface_keyword` : str
If not None (the default), the handler function will receive
the signal interface as a keyword argument with this name.
`member_keyword` : str
If not None (the default), the handler function will receive
the signal name as a keyword argument with this name.
`path_keyword` : str
If not None (the default), the handler function will receive
the object-path of the sending object as a keyword argument
with this name.
`message_keyword` : str
If not None (the default), the handler function will receive
the `dbus.lowlevel.SignalMessage` as a keyword argument with
this name.
`arg...` : unicode or UTF-8 str
If there are additional keyword parameters of the form
``arg``\ *n*, match only signals where the *n*\ th argument
is the value given for that keyword parameter. As of this
time only string arguments can be matched (in particular,
object paths and signatures can't).
`named_service` : str
A deprecated alias for `bus_name`.
