Our customer wants a tool to aid in production of motion pictures. In this part, we are going to set-up the project framework with empty ui components. Function is added in subsequent parts.

Step 1: Create UI Plugin

To create the a new plugin, open the wizard.

  • File >> New >> Plug-in Development >> Plug-in Project >> Next >

Project name for the feature is com.acme.movie.ui. Next >. In the wizard you should know that you'll have a use for an activator, check that. Also know that the plug-in makes UI contributions, but is not a rich client application. Finish

Open the form editor from plugin.xml. From Overview page make sure This plug-in is a singleton.

Step 2: Create Perspective

Perspective is a viewport to user interface. It is setting for how specific type of work is done in a project (Read More). Our application will have only one perspective, movie production perspective. There will be a model browser (left), an editor for diagram representations (center), a properties view (bottom) and a database view (right). Here is a sketch.

Sketch.png


Let's start. Add Movie Production perspective.

  • Open com.acme.movie.ui / META-INF/MANIFEST.MF >> Extensions
  • Add a new extension, org.eclipse.ui.perspectives
  • A node will appear, select it, right click new >> perspective. Select it.
  • Fill in the fields on the right:
    • id = com.acme.movie.ui.perspective
    • name = "Movie Production"
    • class = com.acme.movie.ui.PerspectiveFactory
  • Create perspective factory class. Click on the blue underlined "Class *:" link, a class instantiation wizard will open. Finish.
  • Make the editor area permanently visible. Edit the class.

<syntaxhighlight lang="java">

   public class PerspectiveFactory implements IPerspectiveFactory {
     @Override
     public void createInitialLayout(IPageLayout layout) {
       layout.setEditorAreaVisible(true);		
     }
   }

</syntaxhighlight>


The empty perspective needs content, let's start with the Model Browser. It should be located on the left-hand side as planned in the sketch. We are going to add a perspective extension that states that, in this perspective there is a Model Browser view that is located to the left of the editor area. FYI the identifier of the editor area is org.eclipse.ui.editorss.

To customize a model browser for the movie production case, we cannot directly use any existing view extension in our perspective. Therefore we need to create a new view extension to be able to parametrize the view properly later in the tutorial.

Add the new view extension.

  • 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
    • category = com.acme.movie.ui.category
    • class = org.simantics.browsing.ui.swt.GraphExplorerView


Now that we have the Productions browser view, add it to the perspective.

  • Add new extension org.eclipse.ui.perspectiveExtensions
  • Put com.acme.movie.ui.perspective as targetID
  • Add production browser
    • com.acme.movie.ui.perspective >> right-click >> new >> view
    • id = com.acme.movie.ui.productions
    • relationship = left
    • relative = org.eclipse.ui.editorss
    • ratio = 0.2
    • visible = true
    • closable = false


Apply the same steps to add property view at the bottom.

  • com.acme.movie.ui.perspective >> right-click >> new >> view
  • id = org.simantics.browsing.ui.graph.propertyView
  • relationship = left, org.eclipse.ui.editorss
  • ratio = 0.7
  • visible = true
  • closable = false


And put symbol library to the right.

  • com.acme.movie.ui.perspective >> right-click >> new >> view
  • id = org.simantics.diagram.symbollibrary.managed
  • relationship = left
  • relative = org.eclipse.ui.editorss
  • ratio = 0.6
  • visible = true
  • closable = false

Step 3: Create Feature

Feature is a set of plug-ins grouped into a single manageable unit. In the final release the application would be delivered as a Feature. Features can be installed from an update site using Simantics Project Manager (SPM).

Create feature

  • Open wizard File >> New >> Plug-in Development >> Feature Project >> Next >
  • Project name for feature is com.acme.movie.feature. Next >.
  • The feature includes both com.acme.movie.ontology and .ui plugins, check those. Finish

Step 4: Create Product

But for development the feature is not enough, we need a product.

Create a new product configuration

  • File >> New >> Plug-in Development >> Product Configuration >> Next >
  • Select com.acme.movie.ui as parent folder and put Movie.product for filename. Finish

Create Product extension

  • Open Movie.product
  • Select New Product. A wizard will open. Leave Defining Plug-in as com.acme.movie.ui and Product ID product.
  • Select org.simantics.workbench.application as Product Application. Finish.
  • Open Movie.product and Overview tab sheet from the editor bottom.
    • Add values for ID, Version and Name; say com.acme.movie, 1.0 and "Motion Picture Planner"
    • Choose org.simantics.workbench.product as Product and org.simantics.workbench.application as Application
    • Select "The product configuration is based on: features"
  • Open Dependencies tab sheet from the editor bottom.
    • Add org.simantics.sdk
    • Add com.acme.movie.feature
    • Save file.

Step 5: Simantics Feature

Simantics feature is an configuration extension. It is needed for automated management. See Project Development.

Add Simantics Project Feature

  • Open UI plugin settings: org.com.acme.movie.ui >> plugin.xml
  • Add some plug-in dependencies: Dependencies >> Required Plug-ins >> Add...
    • org.simantics.project, org.simantics.db, org.simantics.utils, org.simantics.utils.datastructures
  • Add org.simantics.project.feature extension: Extensions >> Add... >> org.simantics.project.feature
  • id = com.acme.movie.feature
  • label = Movie Production Feature
  • published = true
  • class = com.acme.movie.ui.ProjectFeature

Create Project Feature class and set the default perspective.

  • Instantiate the class: click the blue class*. link to open a wizard. Finish
  • Add method configure(). Note, you can automatically import dependency classes with (ctrl-shift-o, organize imports).

<syntaxhighlight lang="java">

   public class ProjectFeature extends AbstractProjectFeature implements IProjectFeature {

@Override public void configure() throws ProjectException {

           getProject().setHint(ProjectKeys.DEFAULT_PERSPECTIVE, "com.acme.movie.ui.perspective");

}

   }

</syntaxhighlight>

Create install group.

  • Open UI plugin's extensions: org.com.acme.movie.ui >> plugin.xml >> Extensions
  • Select your feature Movie Production Feature
  • Add installGroup right-click >> New >> installGroup
  • id = com.acme.movie.feature.group

Step 6: Run it

OK, you have now a feature and a product configuration. Give it a go.

  • Open Movie.product
  • Click Launch an Eclipse application

If everything goes fine a simantics platform should start and open up. It should look like this, if not, you can look for help in the tutorial source codes at https://www.simulationsite.net/svn/simantics/tutorials/trunk/

Tip.png If your perspective The Simantics Workbench application will automatically remember the state of the workbench UI between sessions (executions of the application). First and foremost, it will remember the open perspectives, their layouts and open editors. If you manage to mess up your perspective or just otherwise want to return it to the default layout, select from main menu Window >> Reset Perspective... This will reset your perspective's layout according to the current perspective extension specifications.
