Ptidej UI Viewer

The Ptidej UI Viewer project provide interfaces and classes used by all the viewers. In particular, it provides the ptidej.viewer.IRepresentation interface that is the “model” (as in Model-View-Controller) of any viewer. This interface allows managing PADL models, Ptidej UI models, original sources, occurrences…

It is essential that any viewer uses this interface for its model, as it allows extensions to the viewers to work seamlessly regardless of the viewer implementation. Extensions are available in the Ptidej UI Viewer Extensions project.

There are implementations of different viewers. The most usable currently is run through the class ptidej.viewer.ProjectViewer in project Ptidej UI Viewer Standalone Swing. There exists also an Eclipse plug-in using SWT to display models but this plug-in is currently outdated.


To assure the independence of the graphical representation, of the analyses and UI analyses, and of the extensions from the viewers and underlying graphical frameworks (AWT or SWT), Ptide UI Viewer provides several layers of models and canvas. A instance of ModelGraph is a graphical representation of an AbstractLevelModel. Such an instance must be embedded into an instance of Canvas. ModelGraph and Canvas are independent of the underlying graphical framework. Viewers and users can interact with them through two interfaces SelectionListener and CanvasListener following the Observer design pattern. An instance of Canvas can be finally embedded into either an AWTCanvas or SWTCanvas for integration in a user-interface.
