Is there any solid documentation for BeanInfo definitions? The SDK document says to refer to the examples, but the examples are pretty sparse on BeanInfo data.

For example, how would I define a boolean property?

Well, one thing to know is that they aren’t our invention. That means you can read some more background info about them [elsewhere](http://download.oracle.com/javase/tutorial/javabeans/introspection/index.html).

Adding a boolean property would be simple, there are basically two steps for adding any sort of property.

1. Create the getter/setter pair.

To expose a property, you need a getter/setter pair of methods on your component class itself. For a boolean property called [tt]awesomeMode[/tt], the getter/setter should look like this:

[code]public boolean isAwesomeMode() {  
return awesomeMode;  
}

public void setAwesomeMode(boolean val) {  
this.awesomeMode=val;  
}[/code]

2. Add the property to the bean info

To add properties in the bean info, override initProperties(). (don’t forget to call super.initProperties).

Then have a line something like this:

```auto
addProp("awesomeMode", "Be Awesome?", "If true, the component will be awesome", CAT_BEHAVIOR);
```
