Tutorial

This is a brief Howto that describes the creation of a new Presentation Plug-In for ProR.

Headline Presentation Plugin: The Requirements

The requirements are:

• The Presentation shows the configured attribute in a bigger font.
• The Presentation does not support automatic line wrapping.
• The font size can be configured.

Implementation

Step by step instructions.

Create a new Plug-In Project

• Create a new "Empty EMF Project".
• As a convention, start its name org.eclipse.rmf.pror.reqif10.presentation.xxx. We call it org.eclipse.rmf.pror.reqif10.presentation.headline.

Create the EMF Model Extension

Every Presenation must extend the ReqIF Model. This is fairly important to get right.

• Create a new "Ecore Model"
• Store it in the folder model (should already exist) and call it Headline.ecore.
• Leave all the other Defaults and create the model. It should consist of a top-level element (starting with "platform:/...") and an empty package.
• Select the package and configure it in the Properties-View as follows:
  • Name: headline
  • Ns Prefix: headline
  • Ns URI: http://pror.org/presentation/headline
• We need to refer to the ProR UI Model to extend it.
  • Make sure that the Project org.eclipse.rmf.pror.reqif10 is in your workspace and open.
  • In your model editor for Headline.ecore, right-click and select "Load Resource..."
  • Select configuration.ecore (platform:/resource/org.eclipse.rmf.pror.reqif10/model/configuration.ecore)
• Now we create the required new Configuration Class
  • Right-Click on the "headline" package
  • Create a new Child of type "EClass"
  • Configure it in the Properties as follows:
    • ESuperTypes: ProRPresentationConfiguration
    • Name: HeadlineConfiguration
• We may as well add the Attribute for Font Size at this time:
  • Right-Click on HeadlineConfiguration and create a new Child of type EAttribute
    • Name: size
    • EType: EInt
    • Lower Bound: 1 (required field)
