For clarity, the source code presented throughout this guide is abridged. Import statements are omitted and package names are not shown. Source Code for the Sample Widgets provides the full, unabridged source code listings showing the import statements that identify the package names of the referenced classes and interfaces.
Similarly, the configuration files in the examples show only the domain configuration entry relating to the configuration of the widget just presented. The real configuration file within an application component will typically contain all of the configuration entries for all of the domain definitions to which customizations have been applied.
