Detailed Description
UndoManager handles the undo stack.UndoManager is the engine of the undo/redo handling. When ever an undoable action happens an UndoState object will be sent to the UndoManager which then stores the state in the undo stack. When an undo is requested the state is send back to it's creator which is then responsible for doing the actual undo or redo.
UndoManager also handles the UndoGuis by linking them together and reporting all undo/redo actions to the guis for them to update the visual representation. For this to work all UndoGuis need to be registered to the UndoManager with the registerGui() method.

Start a transaction.
After this method has been invoked UndoManager will switch to the transaction (silent) mode where it does not report actions to the attached UndoGui widgets but stores all incoming UndoState objects into the transaction container which after call to the method commit() will be sent to the guis as a single undo action. Transaction can be named when starting it or naming can be done when commiting it.
- Parameters:
-
targetName name for the target of this transaction (f.e. "Selection") targetPixmap Icon for the target on which this transaction works. this icon will be drawn first when the action is presented in Action History window and icon for the action will be drawn over this one. name name for the transaction (f.e. "Move" would make with the above "Move Selection") The result can only be used for initializing a Transaction object, eg. on the stack: Transaction groupTransaction(undoManger->beginTransaction(...)); or the heap: Transaction* groupTransactionPtr = new Transaction(undoManger->beginTransaction(...)); description description for the transaction actionPixmap icon for the action performed by the transaction

- commit()

| bool UndoManager::isTransactionMode | ( | ) |
Cancels the current transaction and deletes groupped UndoStates.
Nothing from canceled transaction will be sent to the undo gui widgets. Commit the current transaction.
Current transaction will be commited and UndoManager will be switched to the normal mode. Commited transaction will be sent to the attached undo gui widgets and it will show up there as a single undo action. Details used as a parameter will be details shown in the gui widgets.
- Parameters:
-
targetName name for the target of this transaction (f.e. "Selection") targetPixmap Icon for the target on which this transaction works. this icon will be drawn first when the action is presented in Action History window and icon for the action will be drawn over this one. name name for the action description description for the action actionPixmap icon for the action performed by the transaction
