These entries are added automatically by the framework in DiagramEditorContextMenuProvider.addDefaultMenuGroupRest if an action for them is available in the tool.

So one option would be to remove the actions in DiagramEditorActionBarContributor, the other to provide your own context menu provider (as subclass of DiagramEditorContextMenuProvider) in DiagramBehavior.createContextMenuProvider.

I hope to create mine context menu provider. I must modify the createContextMenuProvider in DiagramBehavior. But I don't want to modify the DiagramBehavior.java. Can i create a new DiagramBehavior as subclass of DiagramBehavior? Where should I put the new DiagramBehavior ?

Yes, you will need to create a subclass of DiagramBehavior and just override createContextMenuProvider. The creation of that class needs to happen in your own subclass of DiagramEditor (method createDiagramBehavior).

HTH,

Does the DiagramEditor use the extension point org.eclipse.ui.editors in plugin.xml?
Can I override the isAvailable method in updatefeature and RemoveFeature?
@Override
public IRemoveFeature getRemoveFeature(IRemoveContext context) {
return new DefaultRemoveFeature(this) {
@Override
public boolean isAvailable(IContext context) {
return false;
}

};
}
Another one:
How can I remove or disable the align top, align middle in edit menu?

Not sure what exactly you mean with "use", but the DiagramEditor class (or its subclass) needs to be registered for your file extension in plugin.xml.

Surely you can override the isAvailable method. Not sure what you intend to do, in case it is for trying to remove the feature from the context menu, I do not think that will help.

In general you can remove menu entries by removing their actions in DiagramEditorActionBarContributor (or rather your subclass of it, remember to register it together with your DiagramEditor in plugin.xml).

HTH,
Michael
