Detailed Description
This is a QDialog subclass that is aware of the undo-redo sub-system.
Many dialogs show information about server manager objects. The user can change the information and then when he/she hits "Accept" or "Apply", we change the underlying server manager object(s). For this change to be undoable, it is essential that the undo set generation is commenced before doing any changes to the server manager. This manages the start/end of building the undo stack for us. For any such dialogs, instead of using a QDialog, one should simply use this. One can use the accepted(), finished() signals safely to perform any changes to the server manager. However, is should not override the accept() or done() methods, instead one should override acceptInternal() or doneInternal().
