Re: [dtp-dev] Add more nodes to Schema tree node

[Der Ping Chou <dpchou@xxxxxxxxxx>]

Brian is correct, it is flexible in
term of what format is used for your EMF model (ecore, rose uml or xml).
The reason that ModelBase sub-project uses IBM Rational Rose is for the
documentation purpose.

Hi Anthos,

Not necessarily, you can create a new ecore that references the SQL Model
ecore file and then create a genmodel file and create it that way. It's
a
little tricky with EMF, but there are some good EMF books out now that
should help you to go that route. The SQL Model folks like to use Rational
Rose. But it's not the only way.

Good luck!

Hi Brian

Do I need to use Rational Rose to modify the Rose model to extend the SQL
Model's ecore EMF model definition ?

Anthos

  Hi Anthos...

  If you take a look at these two links, you'll see some code that
provides
  a
  basic example of extending the model and adding your own objects
to the
  tree. I recently had to go through this process myself for one of
the
  Sybase databases.

  http://www.eclipse.org/datatools/project_modelbase/modelbase_doc/EclipseWorld/EclipseWorld_701_Building_with_the_Data_Tools_project.ppt

  http://www.eclipse.org/downloads/download.php?file=/datatools/downloads/eclipseworld05/DTP_EclipseWorld.zip


  Basically it amounts to doing a few things...

  1) Extending the base SQL Model's ecore EMF model definition and
  generating
  your own model extensions.
  2) Creating a catalog loader (like Larry's suggesting).
  3) Creating logical containment elements to add the new elements
to the
  view (logical containment extension point)
  4) Creating navigator content extensions to put new elements in
the tree
  (along with the new node IVirtualNode classes)
  5) Adding a label service (extension point) to contribute icons
for those
  nodes.

  Hopefully the EclipseWorld example will help.

  Thanks Larry. How about if I want to add nodes that are currently
not
  there
  ?

    I am bit puzzled to tell you that I dont see any much code
in
    DerbyCatalogProvider which would add more nodes to the view.

  http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.datatools.connectivity/plugins/org.eclipse.datatools.connectivity.derby/src/org/eclipse/datatools/connectivity/internal/derby/catalog/DerbyCatalogProvider.java?rev=HEAD&cvsroot=Datatools_Project&content-type=text/vnd.viewcvs-markup



    Should I be using public void
  setInitializationData(IConfigurationElement
    config, String propertyName, Object data) method ?
