Detailed Description

UndoGui is a virtual superclass for undo/redo widgets.

UndoGui is a virtual superclass for all the classes that wants to represent undo/redo data. Subclasses must be registered to the UndoManager instance. Subclasses are expected to keep the whole stack with them and they must be able to work undo/redo situations by themselves. Only new undo actions and steps (undo or redo) are reported back.

Parameters

steps

Number of steps to take
