Undo manager interface for View.
The UndoManager interface can be implemented to provide custom undo management to a Buffer. Use Buffer::set_undo_manager() to install a custom undo manager for a particular source buffer.
Use UndoManager::can_undo_changed() and UndoManager::can_redo_changed() when respectively the undo state or redo state of the undo stack has changed.

| void Gsv::UndoManager::begin_not_undoable_action | ( | ) | 
Begin a not undoable action on the buffer.
All changes between this call and the call to end_not_undoable_action() cannot be undone. This function should be re-entrant.
| bool Gsv::UndoManager::can_redo | ( | ) | const | 
Get whether there are redo operations available.
true if there are redo operations available, false otherwise.| void Gsv::UndoManager::can_redo_changed | ( | ) | 
Emits the 'can-redo-changed' signal.
| bool Gsv::UndoManager::can_undo | ( | ) | const | 
Get whether there are undo operations available.
true if there are undo operations available, false otherwise.| void Gsv::UndoManager::can_undo_changed | ( | ) | 
Emits the 'can-undo-changed' signal.
| void Gsv::UndoManager::end_not_undoable_action | ( | ) | 
Ends a not undoable action on the buffer.

| void Gsv::UndoManager::redo | ( | ) | 
Perform a single redo.
Calling this function when there are no redo operations available is an error. Use can_redo() to find out if there are redo operations available.

Emitted when the ability to redo has changed.
void on_my_can_redo_changed() | Glib::SignalProxy0< void > Gsv::UndoManager::signal_can_undo_changed | ( | ) | 
Emitted when the ability to undo has changed.
void on_my_can_undo_changed() | void Gsv::UndoManager::undo | ( | ) | 
Perform a single undo.
Calling this function when there are no undo operations available is an error. Use can_undo() to find out if there are undo operations available.
