Undo is a method used to revert the last editing action performed in the control. Undo is performed when the Ctrl+Z (or Meta+Z on macOS) key combination is handled for the control. Pressing Ctrl+Z causes the value in Text to revert to its value before editing. A subsequent Ctrl+Z key press causes the edited value to be toggled.
Undo calls the Undo method in the widgetset class when its handle has been allocated.
