A BeanInfo class describes the properties of a JavaBean and provides an icon forit.
Writing a BeanInfo is pretty easy. See this example heavily-commented Date_CABeanInfo java source code.
In the comments are hidden many useful hints. Studying the example code in the
BeanBox is more helpful than reading the JavaBean spec.
For example, study the MoleculeEditor to provide a list of
allowable choices fora String property. For more complex
PropertyEditors based on implementing the java.beans.PropertyEditor interface or extending the PropertyEditorSupport class
The key thing to understand is that there is no glue between the JavaBean and the
BeanInfo class other than the naming convention. If your
Bean is called Jim then the corresponding BeanInfo class has to be called JimBeanInfo
and has to be stored in the same directory. There is glue in the other direction, via
the bean’s BeanClass passed to the various
PropertyDescriptor constructors in the BeanInfo code. Normally JavaBeans and their corresponding BeanInfo classes are bundled up together with other beans and
dependent classes in a jar file.
