overridevirtual |
Applies a change to the document.
This function must be implemented in the derived class. Calling QUndoStack::push(), QUndoStack::undo() or QUndoStack::redo() from this function leads to undefined beahavior.
The default implementation calls redo() on all child commands.
Reimplemented from QUndoCommand.

overridevirtual |
Reverts a change to the document.
After undo() is called, the state of the document should be the same as before redo() was called. This function must be implemented in the derived class. Calling QUndoStack::push(), QUndoStack::undo() or QUndoStack::redo() from this function leads to undefined beahavior.
The default implementation calls undo() on all child commands in reverse order.
Reimplemented from QUndoCommand.
