| /** |
| * <p> |
| * A preference page that is capable of displaying and editing the bindings |
| * between commands and user input events. These are typically things like |
| * keyboard shortcuts. |
| * </p> |
| * <p> |
| * This preference page has four general types of methods. Create methods are |
| * called when the page is first made visible. They are responsible for creating |
| * all of the widgets, and laying them out within the preference page. Fill |
| * methods populate the contents of the widgets that contain collections of data |
| * from which items can be selected. The select methods respond to selection |
| * events from the user, such as a button press or a table selection. The update |
| * methods update the contents of various widgets based on the current state of |
| * the user interface. For example, the command name label will always try to |
| * match the current select in the binding table. |
| * </p> |
| * <p> |
| * Updated in 3.4 to work with a model backed by the real KeyBinding and |
| * ParameterizedCommand objects. |
