The SetSnapshotFunction method in the UndoSystem class is used to set a function that generates a snapshot for the undo system. However, this method is marked as obsolete and is no longer functional. The recommended approach is to manually create and restore snapshots within the undo/redo actions provided to the UndoSystem.Insert method.
Since SetSnapshotFunction is obsolete, it is advised not to use this method in new code. Instead, manage snapshots manually by implementing them in the actions passed to UndoSystem.Insert. This ensures that your undo/redo functionality remains robust and compatible with the current system.
// Example of how to use UndoSystem.Insert instead of SetSnapshotFunction
// Define undo and redo actions
Action undoAction = () => {
// Code to revert changes
};
Action redoAction = () => {
// Code to reapply changes
};
// Insert the undo/redo entry into the UndoSystem
UndoSystem.Insert("Change Title", undoAction, redoAction);
