Hi,
I am trying to display custom labels for the left, right, and ancestor compare/merge viewers. To do this, I have implemented a class like the following (I am only showing the relevant code here):
public class MyEditorInput extends CompareEditorInput {
protected Object prepareInput(IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
CompareConfiguration compConfig = getCompareConfiguration();
compConfig.setAncestorLabel("My Ancestor Label");
compConfig.setLeftLabel("My Left Label");
compConfig.setRightLabel("My Right Label");
}
}
However, the viewers are still displayed with different titles.
I know that the labels I set myself are only used "if the element for which a label is requested does not have a left/right/ancestor contributor or the element does not have a registered label provider or the label provider returns null as the label". To check that this is not the case, I set a breakpoint in the getLeftLabel(Object input) method of the CompareConfiguration$DefaultLabelProvider inner class. I can see that this method always returns the values I have set, so I don't know why the displayed labels are still different.
Cheers,
Vlad

Hi Vlad,
are you talking about the labels on top of the left and right tree viewer in the tree content merge viewer?
If yes, you could try to add a storage path adapter to the left/right/origin resource of the comparison scope of your comparison input. This should allow you to control the left and right titles of the tree content merge viewer:
StoragePathAdapter storagePathAdapter = new StoragePathAdapter(label, isLocal);
resource.eAdapters().add(storagePathAdapter)
Hope that helps!
Best wishes,
Philip

Hi Vlad,
I'm not exactly sure how to trace that, but what happens if you put a breakpoint in EMFCompareConfiguration.getLabel and go back up in the stack? is there any place where your labels are ditched in favor of generic ones? I don't really have a setup to test this atm.
