using public interface.

I just added a fix in InsertText public method to add an UndoRecord. From outside of a TextEditor I was unable to undo a text insertion. |
User must implement how to undo the UndoRecord received himself.

Hello,
First draft version of an external undo buffer interface.
The concept is simple, this interface consists on a single method that can receive an UndoRecord& as ar gument. This method is called only if the TextEditor as an mExternalUndoRecordBuffer not null.
I had to set public a lot of your classes: UndoRecord, EditorState and the type UndoBuffer.
I choose to modify as less possible things, but I think it should be better to introduce a boolean to says is undobuffer is internal or external and then use that boolean to avoid all internal undo/redo stuff.
I don't really know why UndoRecord.Undo() takes a TextEditor pointer. Is is to avoid to store it in each Record ?
Let me know your impressions about my proposal.
Cheers
