JWT Extensions

This page provides information on how to extend the JWT Workflow Editor (JWT-WE).

Overview

The JWT Workflow Editor defines several extension points and mechanisms that allow users to customize and extend the abilities and properties of JWT-WE without changing the editor itself. However, there may be cases in which it becomes necessary to alter the Workflow Editor code itself, notably when the new features need to be implemented by committers of the JWT project. This page is intended to describe how third party suppliers can extend JWT-WE (e.g. with custom views on the model elements) through external plugins using the defined extension points as well as how JWT committers can deal with recurring tasks like adding new options to the Eclipse preferences dialog.

Extending JWT-WE through Plugins

Adding Property Sheet Pages

The workflow editor contains support for a multi-tab property sheet (TabbedPropertiesView) which is only activated if additional tabs are provided by plugins. If this is not the case, the classical property sheet is used which does not display any tabs. If the multi-tab sheet is used, a single tab Standard is always shown, which contains the model element properties as would be normally shown in the classical property sheet.

The classical property sheet without tabs

To add a new property sheet page to the editor, it is necessary to define a new property tab in the plugin.xml and fill it with one or more property sections.
