EventManager

- -

The goal of the EventManager is to make wxWindows events more -'Pythonic' (ie. object-oriented) and easier to work with, without -impacting performance. It offers these features: - -

-

- -

Usage

- -

The EventManager class has three public methods. First get a -reference to it: - -

-  from wxPython.lib.evtmgr import eventManager
-
- -

...and then invoke any of the following methods. These methods are -'safe'; duplicate registrations or de-registrations will have no -effect. - -

Registering a listener: - -

-  eventManager.Register(listener, event, event-source)
-
- - -

De-registering by window: - -

-  eventManager.DeregisterWindow(event-source)
-
- - -

De-registering by listener: - -

-  eventManager.DeregisterListener(listener)
-
- -

Simple Example: - -

-  from wxPython.lib.evtmgr import eventManager
-
-  aButton = wxButton(somePanel, -1, 'Click me')
-  eventManager.Register(self.someMethod, EVT_BUTTON, aButton)
-
- -

See the demo code as well as the documentation in the source of -wxPython.lib.evtmgr for more details. - - -
