Eclipse GMF

The GMF Runtime has a set of frameworks to help the development of Eclipse graphical editors:

• Reusable components for graphical editors
• A standardized model to describe diagram elements
  • Semantic and diagram models are distinct
• Enables open and extensible graphical editors
• Command infrastructure that bridges EMF and GEF
  • EMF provides a runtime infrastructure to instantiate and manipulate models (among other things)
  • GEF is an MVC-based framework to create graphical editors
• Leverage various other technologies:
  • EMFT: Transactions, Validation, OCL
  • Apache Batik

I am having a problem using GMF as described on this page.

Eclipse UML2 Tools and Graphical Modelling Framework (GMF)

 

The data for this diagram is held in these files:

• Package.ecore
• Package.ecore_diagram

Generating EMF Model

Create Project

Start Eclipse and make sure any existing projects are closed.

Menu -> File -> New -> Project

select 'new CMF Project' the next

Enter

• project name: I used com.mjb.es.math

press 'Next' and in next page enable 'dashboard'

then 'Finish'

File -> New -> Package

give it name: mathModel

Create the following interfaces

• BinaryOp.java
• BinaryOpGraded.java
• BinaryOpTable.java
• MathDiagram.java
• MNode.java
• MType.java
• MTypeInteger.java
• MTypeMultivector.java
• MTypeRational.java
• MTypeScalar.java
• MTypeTensor.java
• UnaryOp.java

Right click on model folder

new -> other -> emf models

Change the folder to "model"

filename = mathModel.genmodel

 

select this in the package explorer

and right click on 'Es' in es.genmodel and click on 'generate all'

this generates:

• Model code
• Edit code
• Editor code
• Test Code

Generate Model

Generate the generator model file from annotated java:

Menu -> File -> New -> Eclipse Modeling Framework -> EMF Model

This is explained in more detail on this page.

Create 'Graphical def Model'

• In GMF Dashboard click on 'create' in 'Graphical def Model' box
• set filename to: euclideanspace.gmfgraph
• press finish

or

derive it from

Create 'Tooling Definition Model'

• In GMF Dashboard click on 'create' in 'Tooling Definition Model' box
• set filename to: euclideanspace.gmftool
• press finish

select the file and right click on 'tool registary' select pallette

 

Create 'Mapping Definition Model'

• In GMF Dashboard click on 'combine'
