Открытые методы

Метод	Описание
ClearAll ( ) : void	Clears both the undo and redo stack.
ClearRedoStack ( ) : void	Call this method, if you want to clear the redo stack
DiscardOriginalFileMarker ( ) : void	Discards the current "original" marker.
EndUndoGroup ( ) : void	Stops grouping changes.
MarkAsOriginalFile ( ) : void	Marks the current state as original. Discards any previous "original" markers.
Push ( IUndoableOperation operation ) : void	Call this method to push an UndoableOperation on the undostack. The redostack will be cleared if you use this method.
PushOptional ( IUndoableOperation operation ) : void	Call this method to push an UndoableOperation on the undostack. However, the operation will be only stored if the undo group contains a non-optional operation. Use this method to store the caret position/selection on the undo stack to prevent having only actions that affect only the caret and not the document.
Redo ( ) : void	Call this method to redo the last undone operation
StartContinuedUndoGroup ( object groupDescriptor = null ) : void	Starts grouping changes, continuing with the previously closed undo group if possible. Maintains a counter so that nested calls are possible. If the call to StartContinuedUndoGroup is a nested call, it behaves exactly as StartUndoGroup(), only top-level calls can continue existing undo groups.
StartUndoGroup ( ) : void	Starts grouping changes. Maintains a counter so that nested calls are possible.
StartUndoGroup ( object groupDescriptor ) : void	Starts grouping changes. Maintains a counter so that nested calls are possible.
Undo ( ) : void	Call this method to undo the last operation on the stack

Описание методов

ClearAll() публичный Метод

Clears both the undo and redo stack.

public ClearAll ( ) : void
Результат	void

ClearRedoStack() публичный Метод

Call this method, if you want to clear the redo stack

public ClearRedoStack ( ) : void
Результат	void

DiscardOriginalFileMarker() публичный Метод

Discards the current "original" marker.

public DiscardOriginalFileMarker ( ) : void
Результат	void

EndUndoGroup() публичный Метод

Stops grouping changes.

public EndUndoGroup ( ) : void
Результат	void

MarkAsOriginalFile() публичный Метод

Marks the current state as original. Discards any previous "original" markers.

public MarkAsOriginalFile ( ) : void
Результат	void

Push() публичный Метод

Call this method to push an UndoableOperation on the undostack. The redostack will be cleared if you use this method.

public Push ( IUndoableOperation operation ) : void
operation	IUndoableOperation
Результат	void

PushOptional() публичный Метод

Call this method to push an UndoableOperation on the undostack. However, the operation will be only stored if the undo group contains a non-optional operation. Use this method to store the caret position/selection on the undo stack to prevent having only actions that affect only the caret and not the document.

public PushOptional ( IUndoableOperation operation ) : void
operation	IUndoableOperation
Результат	void

Redo() публичный Метод

Call this method to redo the last undone operation

public Redo ( ) : void
Результат	void

StartContinuedUndoGroup() публичный Метод

Starts grouping changes, continuing with the previously closed undo group if possible. Maintains a counter so that nested calls are possible. If the call to StartContinuedUndoGroup is a nested call, it behaves exactly as StartUndoGroup(), only top-level calls can continue existing undo groups.

public StartContinuedUndoGroup ( object groupDescriptor = null ) : void
groupDescriptor	object	/// An object that is stored with the undo group. /// If this is not a top-level undo group, the parameter is ignored. ///
Результат	void

StartUndoGroup() публичный Метод

Starts grouping changes. Maintains a counter so that nested calls are possible.

public StartUndoGroup ( ) : void
Результат	void

StartUndoGroup() публичный Метод

Starts grouping changes. Maintains a counter so that nested calls are possible.

public StartUndoGroup ( object groupDescriptor ) : void
groupDescriptor	object	/// An object that is stored with the undo group. /// If this is not a top-level undo group, the parameter is ignored. ///
Результат	void

Undo() публичный Метод

Call this method to undo the last operation on the stack

public Undo ( ) : void
Результат	void
