a scrolledtext widget feels like a text widget but also has a vertical scroll bar on its right later options may be added to add a horizontal bar as well to make the bars disappear automatically when not needed to move them to the other side of the window etc configuration options are passed to the text widget a frame widget is inserted between the master and the text to hold the scrollbar widget most methods calls are inherited from the text widget pack grid and place methods are redirected to the frame widget however copy geometry methods of self frame without overriding text methods hack copy geometry methods of self frame without overriding text methods hack
