Outliner

Outliner is a user interface package which extends the standard JFC/Swing JTree with:

Heterogeneous outlines: different nodes in the outline may be displayed with different renderers, rather than all nodes sharing the same renderer.
Alternative renderings: a node in the outline may be re-rendered with alternative renderers (alternate views).
Outline construction: provides a protocol for incrementally constructing outlines. Given a new object, a renderer is found (based on its class and interfaces by default), and the renderer constructs an outline node (or nodes), draws it, and specifies its chldren if the node is expanded.

For examples of renderers for inspecting objects, see Jexa; for a renderer for displaying a call tree with children nested between invocation and result nodes, see Traveler. For details, see Outliner javadocs.

Outliner Release Notes

1999-07-05: To facilitate incremental updates, added static getModel method so it is possible to get the model displaying an OutlineNode to notify the model that the node has changed and should be redisplayed.

1999-06-09: JFC/Swing: Outliner has been rearchitected, building on javax.swing.JTree to improve updating. The new architecture allows multiple OutlineMakers rather than just one system-wide table of renderers. Multiple renderers may be installed per interface in an OutlineMaker rather than just one; these show up as alterative renderers. Examples of outline renderers extending the new architecture are in the Jexa documentation. Localization: Outliner may be localized; menu strings are properties that may be overridden according to language of default locale for international use. (AWT Version: For users who have built outline generators based on the old architecture, the old AWT Outliner has been updated to use the monospaced font, and moved to edu.mt.ai.psg.outliner.awt. The AWT version will be phased out in the future.)
