### Public Types

- enum Type { NoEvent, Connected, Mouse, Focus, ..., Embed }

## Detailed Description

The QWSEvent class encapsulates an event in Qtopia Core.

When running a Qtopia Core application, it either runs as a server or connects to an existing server. In the client/server protocol, each event is sent as a QWSEvent object to the server.

QWSEvent provides the Type enum specifying the origin of the event. Internally, each type is represented by a QWSEvent subclass, e.g. QWSKeyEvent.

Note that the QApplication class provides the virtual qwsEventFilter() function which can be reimplemented to get direct access to all QWS (Q Window System) events that are received from the QWS master process.

See also QWSServer and QWSClient.
