      Parameters:
      viewer - The viewer, which contains the EditParts.
      modelObject - The model Object, which EditPart to select.

    • calculateTranslation

      org.eclipse.draw2d.geometry.Point calculateTranslation(org.eclipse.gef.EditPart source, org.eclipse.gef.EditPart target)
      Returns the translation between the coordinate-systems of EditParts. It will translate from the coordinate-system of the source EditPart to the coordinate-system of the target EditPart. Both EditParts must be an instance of GraphicalEditPart. Otherwise it throws an Exception.
      Parameters:

      Returns:
      Returns the translation between the coordinate-systems of EditParts.

    • getLayoutConstraint

      Object getLayoutConstraint(org.eclipse.gef.EditPart editPart)
      Returns the layout constraint for the given EditPart. It returns null, if the constraint can not be determined, for example because the child has no parent or the parent has no LayoutManager.
      Parameters:
      editPart - The EditPart for which to return the layout constraint.
      Returns:
      Returns the layout constraint for the given EditPart.
