I have (at least) two different types of commands:

  1. Commands which can be saved
  2. Commands which can't be saved


If I use the GEF org.eclipse.gef.commands.CommandStack I can't distinguish which one of the command-types is set. So I can't figure out If I have to save my application.

Is there a way to set my own CommandStack?

Yes you can. Use the EditDomain.setCommandStack(CommandStack stack) method right after you create the edit domain.

Yes, but CommandStack isn't an interface ... and I have no access to the member saveLocation ... Sad

Well, that's a different story.

You will have to do it in another way. Maybe don't get dirty state from the CommandStack.isDirty() but use the CommandStackEventListener somehow.
It will tell you what command is executed/redoed/undoed, so you could copy the CommandStack implementation to your own and use it for returning the dirty state.

Hey Jan,

thank you for your post! Smile That works ... but for me it sounds more like and hack, because I must distribute the functionality of the CommandStack over my application if I want to extend the functionality of the stack.

It is hack Smile But since the CommandStack is not extendable, what can one do?
