The Snapshot method in the UndoSystem class is marked as obsolete. It was originally intended to create a snapshot of the current state, which could be used for undo operations. However, automatic snapshotting is no longer supported. Instead, developers are encouraged to manually manage snapshots by creating and restoring them within the undo/redo actions provided to the UndoSystem.Insert method.
Since the Snapshot method is obsolete, it is recommended to avoid using it in new code. Instead, manage snapshots manually by implementing custom undo and redo actions using the UndoSystem.Insert method. This approach provides more control and flexibility over the undo/redo process.
// Example of using UndoSystem.Insert for manual snapshot management
// Define undo and redo actions
Action undoAction = () => {
// Code to revert changes
};
Action redoAction = () => {
// Code to reapply changes
};
// Insert the actions into the undo system
UndoSystem.Insert("Change Title", undoAction, redoAction);
