Hello Daniel,
thank you for your reply!
I have created my own edit part provider and contributed it over the
extension point "org.eclipse.gmf.runtime.diagram.ui.editpartProviders"
But my "createRootEditPart"-method (where I return my custom
RootEditPart) is never invoked.
Which methods did you override in your edit part provider to get access
to the root edit part of the diagram?
Could you provide me some example-code, please? Thank you very much!
Regards,
Marco

Hi Marco,
You need to configure the edit part provider correctly.
Set a higher priority than the current one (I've put highest).
In the context you must specify it provides the root edit part.
<extension point="org.eclipse.gmf.runtime.diagram.ui.editpartProviders "
id="my-ep-provider">
<editpartProvider class="a.b.RootPartProvider">
<Priority name="Highest">
</Priority>
<context providesRootEditPart="true">
</context>
</editpartProvider>
</extension>
Then the createRootEditPart method will be called.
public RootEditPart createRootEditPart(Diagram diagram) {
return new MyDiagramRootEditPart(diagram.getMeasurementUnit());
}
Cheers,
Daniel
