Call this method when you want to reinitialize the history list.
You should use clear_history() method from Qt_widget_standard_toolbar or the clear() public slot from Qt_widget_history object. You should use the backward() and forward() methods of Qt_widget_history object, or the back() and forward() public slots from Qt_widget_standard_toolbar object.
Deprecated: This slots permit to walk into history. Locks the widget, keeping the widget from being refreshed.
If you lock the widget you should verify that you unlock it somewhere.
This permits Qt to optimize for more speed and less flicker than a call to repaint() does.
