Define EMF Model for ShowViews Command

Create Ecore Model

  • Create model folder in the root directory of your plugin
  • Right click on model folder and select New > Other… > Eclipse Modeling Framework > Ecore Model > Next
  • Choose a name for your model. In our case it will be view.ecore
  • Press Finish

Created model will be opened in the editor and we need to specify package details using Properties View as shown below:

Add ShowViews command class

We need to create new EClass for our ECL command.

  • Create new EClass and change its name to ShowViews in the Properties View
  • Right click your editor and select Load Resource... menu item
  • In the opened dialog press Browse Workspace... button
  • Select org.eclipse.rcptt.ecl.core/model/ecl.ecore package:

  • Add Command from the ECL package as a super type to your ShowViews class.

Add View class

Now we need one more EClass to represent Eclipse View details.

  • Create EClass called View
  • Add three string attributes to this class: id, label and description

Generate java sources

We need to create generation model to build java sources for our model.

  • Right click on the view.ecore file in the Package Explorer and select New > Other… > Eclipse Modeling Framework > EMF Generator Model > Next
  • Default view.genmodel name for generator model is OK for us, so just press Next
  • Select Ecore model item and press Next
  • Click Load button and press Next again
  • Select view.ecore as a root package and add ECL and EMF packages as references. Press Finish

  • In the opened editor select View package and change base package attribute to org.eclipse.rcptt.ecl.example:

  • Right click View package and select Generate Model Core. All necessary java sources will be generated.

Please note, that you should set the same runtime version for view.genmodel as you have for ecl.genmodel in org.eclipse.rcptt.ecl.core.
