JWT Modifications

Revision as of 07:06, 26 September 2008 by (Talk | contribs) (General Standards for Plugins)

This page provides information on how to add modify and add new features to the JWT Workflow Editor (JWT-WE).


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 JWT committers can deal with recurring tasks when adding features to the Workflow Editor like adding new options to the Eclipse preferences dialog (if you're instead looking for information on how to extend JWT-WE through providing external plugins, please take a look at JWT_Extensions).
