Type EventCallback

object --+
         |
        EventCallback

EventCallback (signal, callback, *data) -> EventCallback

Creates a new EventCallback to use as a signal handler for objects.

The EventCallback can be used as container object for event mechanisms, which need signal to method bindings. The connected callback can be invoked using the EventCallback.run() method.

Attributes: signal - Identifier of the event to wait for. callback - Function/method to invoke upon receiving the event. data - Data to pass to the function/method.

Method Details

run(self, *data)

E.run (...)

Invokes the callback of the EventCallback.

If additional data is supplied via the 'data' argument, the already attached callback data in the EventCallback.data attribute will be concatenated to it and the result will be passed to the callback.
