Revision as of 14:40, 6 October 2010

org.simantics.browsing.ui feature (SVN) provides a customizable tree-based browser for data model visualization. These components are collectively called graph explorers.

The cornerstones of graph explorer design are:

  • Generic API, data source independent
  • Highly customizable and extensible
  • UI content production is based on the reactive programming paradigm
    • Keeping the UI up-to-date is a problem of the framework, not the client!
    • Content is produced by performing an acyclic graph of queries
  • Focus on supporting trees and tree-table views.
    • Simple browsers, property tables, etc.

Utilities, extensible base implementations and ready-made mechanisms are available for creating browsers on top of org.simantics.db APIs.

Roadmap

1.2

  • Stabilize the feature, no new features.
  • Documentation:
    • Top-down dokumentaatio tuntuisi hyödyllisemmältä. Ensin esille esimerkit ja tutoriaalit, sitten vasta pohjatason kuvaukset.
    • Käyttöesimerkit:
      • Joitain SWT Snippet-tyylisiä -täysin triviaaleja esimerkkejä mielivaltaisella dummy-datalla
        • Tärkeintä demonstroida ominaisuuksia pienissä erissä, ei kaikkea kerralla
      • Historiadatan esittämiseen käytetty property table on ihan hyvä esimerkki vaikkei vielä mitenkään erityisen Advanced-tasoinen. Ei sisällä mitään editointitoimintoja.
      • Labelerit
      • Modifierit
      • SWT.CHECK
    • Rajapinnat, tärkeimpänä kaikki rajapintojen edellyttämät asiat, jotta explorer toimii oikein
    • Käytössä olevat aputoteutukset rajapintojen päälle
    • GE:n rinnastus JFacen viewereihin (jos se jotakuta auttaa)
    • Sovelluskohdekohtaiset GE:t ja niiden sisäiset mekanismit eivät kuulu tähän dokumentaatioon.

1.3

  • Features:
    • Auto-expand API (~JFace)
    • Noodikohtaisten valintojen propagointi lapsille - esim. viewpoint jonka valinta vaikuttaa lapsinoodeissa tehtyyn viewpoint-valintaan.

Testing

To facilitate automated testing of the browsing framework, we need to:

  • Create a headless testable mockup version of GraphExplorerImpl or add inspection facilities to gain access into the internal model to verify the visual results.
  • Create test facilities for putting contributions into testing
  • IDEA: make the basic GraphExplorer framework a headless component that provides the whole query/contribution framework only excluding the viewer specific part. Viewers, such the current SWT Tree based viewer could then be attached to the explorer's model. The attachment interface should be as minimal as possible to keep the viewer implementations out of the model details and also to keep the viewer implementations simpler.


Sparetime Projects

  • Create a scenegraph-based GraphExplorer
    • "Tree nodes" floating around in 2D space
    • Automatic and animated layouts (consider using graphviz)
