I am writing an application that has an field, which user can edit arbitrarily. I want to show my special undo-button only if there is an action to undo for the field. I want to hide it otherwise. How do I know whether there is an action to undo or not?
Unfortunately there's no reliable way without looking at low-memory globals used by the field code to keep track of the undo state.
