Hi
I have an issues on XYLayoutEditPolicy.In GMF generated code itself,
shapes and connection works properly but after adding XYLayoutEditPolicy
to draw something, the shapes are always located at the left-top corner.
Here is part of DiagramEditPart code.
What should I override the methods?
protected void createDefaultEditPolicies() {
super.createDefaultEditPolicies();
installEditPolicy(EditPolicyRoles.SEMANTIC_ROLE,
new DiagramItemSemanticEditPolicy());
installEditPolicy(EditPolicyRoles.CANONICAL_ROLE,
new DiagramCanonicalEditPolicy());
installEditPolicy(EditPolicy.LAYOUT_ROLE,
new PointShapeXYLayoutEditPolicy());
}
thanks

Hello YJ,

If you are placing this code in an EditPart then you have to type something
like:
(MyDiagram) ((org.eclipse.gmf.runtime.notation.Diagram) getModel()).getElement()

The problem is: you do not have corresponding View createt isn't it?

You have to register own ???ViewProvider cresting corresponding View instance
for new diagram element (or modify generated ???ViewProvider in accordance)
+ register/modify generated ???EditPartProvider to create EditPart based
on a view created on step 1.
