# builder

## Purpose

Property that points to the builder associated with this MVC group.

## Examples

    class SampleController {
        def builder
        def view
        def action = { evt = null ->
            view.containerPanel << builder.panel {
                label("Property: ")
            }
        }
    }

## Description

Every MVC group has its own instance of a `CompositeBuilder`. The builder property is a reference to that instance. You may use it to create new nodes or call explicit methods that have not been contributed to controllers.
