|

* The keywords correspond to <code>java.beans.PropertyDescriptor</code> and
|
||||
* <code>java.beans.FeatureDescriptor</code> properties, e.g. providing a value
|
||||
* for displayName is comparable to <code>FeatureDescriptor.setDisplayName()</code>.
|
||||
* Using createPropertyDescriptor instead of the PropertyDescriptor
|
||||
* constructor and set methods is preferrable in that it regularizes
|
||||
* the code in a <code>java.beans.BeanInfo.getPropertyDescriptors()</code>
|
||||
* method implementation. One can use <code>createPropertyDescriptor</code>
|
||||
* to set <code>FeatureDescriptor</code> attributes, as in "random attribute"
|
||||
* "random object value".
|
||||
* <p>
|
||||
* All properties should provide a reasonable value for the
|
||||
* <code>SHORTDESCRIPTION</code> keyword and should set <code>BOUND</code>
|
||||
* to <code>Boolean.TRUE</code> if neccessary. The remaining keywords
|
||||
* are optional. There's no need to provide values for keywords like
|
||||
* READMETHOD if the correct value can be computed, i.e. if the properties
|
||||
* get/is method follows the standard beans pattern.
|
||||
* <p>
|
||||
* The PREFERRED keyword is not supported by the JDK1.1 java.beans package.
|
||||
* It's still worth setting it to true for properties that are most
|
||||
* likely to be interested to the average developer, e.g. AbstractButton.title
|
||||
* is a preferred property, AbstractButton.focusPainted is not.
