GMF change class hierarhy [message #1032518]

Hi all,

I have generated edit part MyEditPart:

/**
 * @generated
 */
public class MyEditPart extends ShapeNodeEditPart {

And I want to change parent class on MyCustomShapeNodeEditPart that extends from ShapeNodeEditPart as well.

@extends annotation has affect for interfaces, but I need something like this:

/**
 * @generated
 * @extends MyCustomShapeNodeEditPart
 */
public class MyEditPart extends MyCustomShapeNodeEditPart {

Hi Igor,

you can change the generator templates to make your class inherit from your custom shapenodeeditpart for any node you like.

Check:
-> diagram::editparts:NodeEditPart.xpt
-> impl::diagram::editparts:NodeEditPart.xpt
The latter has a declaration:

«DEFINE extendsListContents FOR gmfgen::GenNode-»
«IF hasBorderItems(self)»org.eclipse.gmf.runtime.diagram.ui.editparts.AbstractBorderedShapeEditPart«ELSE»org.eclipse.gmf.runtime.diagram.ui.editparts.ShapeNodeEditPart«ENDIF-»
«ENDDEFINE»

you might want to change.

Regards
Thomas
