Re: Binding to a POJO

Good afternoon!

So, I have a program I'm writing whose primary window is a JFrame. Many
of the JFrame's children are bound to fields within a Java bean.

I was using JGoodies Binding to accomplish this, but then I started
using WindowBuilder Pro, which has very nice support for JSR 295
(BeansBinding).

The often-cited problem with either JGoodies or BeansBinding is this: it
introduces code bloat. Instead of

public void setFoo(Object newFoo) {
  this.foo=newFoo;
}

you have to do this:

public void setFoo(Object newFoo) {
  String oldFoo = this.foo;
  this.foo=newFoo;
  
  // support is a previously-initialized
  // instance of java.beans.PropertyChangeSupport

  support.firePropertyChange(propertyName, oldValue, newValue);
}

I came up with a solution that will allow you to do this instead:

public void setFoo(Object newFoo {
  changeProperty("foo",this.foo,newFoo);
}

How do I do this? I make my bean inherit from PCLBean:
