Preparing to delegate

We start our Renderer by creating a FieldBuilder. We do this because our Renderer isn't going to do all the work. It will delegate the task of rendering the input box to an existing Renderer. The FieldBuilder will store up the settings that we pass to that Renderer.

Figure 1. Setting up a FieldBuilder

025      Field field = ((Field)component);
026
027      final FieldBuilder fieldBuilder = 
028        ComponentBuilderFactory.createFieldBuilder();
029      fieldBuilder.copy(field);
