Tutorial: Model Development

In this part of the tutorial we will focus on implementing the basic functionality for the following parts of the UI:

• Model Browser for modelling movie production cases
  • Basic context menu actions for the browser
    • Add > Movie Project
    • Add > Casting Plan
    • Add > Role
• Property View for editing properties of model entities
• Movie Database Library for searching available movies, actors, directors, etc.

Step 1: Customize Model Browser

To customize the model browser for the movie production case, we cannot directly use the existing view added to the perspective in the previous part of the tutorial. We need to create a new view extension to parametrize the view properly.

Lets add the new view extension.

• Open com.acme.movie.ui / META-INF/MANIFEST.MF >> Extensions
• Add a new extension, org.eclipse.ui.views
• Add view category
  • org.eclipse.ui.views >> right click >> new >> category
  • id = com.acme.movie.ui.category
  • name = Movie Production
• Add view
  • org.eclipse.ui.views >> right click >> new >> view
  • id = com.acme.movie.ui.productions
  • name = Productions
  • class = org.simantics.browsing.ui.swt.GraphExplorerView:browseContext=http://com.acme/Movie-1.0/Productions&uiContext=com.acme.movie.ui.productions&contextMenuId=#ProductionsPopup
  • category = com.acme.movie.ui.category

In the same extension editor, modify the existing view perspective extension to use the new view.

• Find the extension in the tree: org.eclipse.ui.perspectiveExtensions >> com.acme.movie.ui.perspective (perspectiveExtension) >> org.simantics.structural.ui.modelBrowser
• Modify org.simantics.structural.ui.modelBrowser to com.acme.movie.ui.productions
