public class Command
extends EventGenerator
```
Command is an event generator that generates application-level events. Unlike io generators that are related to some hardware input format, the command generator defines its own input format. Basically input and output event are the same. This allows the generation of commands from within MicroUI without relying on an underlying input event format.
This class defines constants for a set of basic commands. The commands defined in this class are typical application-level effects of input events. The advantage of using commands rather than specific input events in an application is that the application can be more portable: it is not tied to specific input devices.
