Functions

connect(receiver, signal=Any, sender=Any, weak=True)

Connect receiver to sender for signal.

• If sender is Any, receiver will receive signal from any sender.
• If signal is Any, receiver will receive any signal from sender.
• If sender is None, receiver will receive signal from Anonymous.
• If signal is Any and sender is None, receiver will receive any signal from Anonymous.
• If signal is Any and sender is Any, receiver will receive any signal from any sender.
• If weak is true, weak references will be used.

---

disconnect(receiver, signal=Any, sender=Any, weak=True)

Disconnect receiver from sender for signal.

Disconnecting is not required. The use of disconnect is the same as for connect, only in reverse. Think of it as undoing a previous connection.

---

safeRef(object)

Return a safe weak reference to a callable object.

---

send(signal, sender=Anonymous, **kwds)

Send signal from sender to all connected receivers.

Return a list of tuple pairs [(receiver, response), ... ]. If sender is not specified, signal is sent anonymously.
