on its orientation
** display_widget (QWidget): optional argument. If entered, the display
will show up over that widget rather than over the main display.

alignment (Qt.Alignment): Where widget should be aligned
depth (int): width/height of the slideBar (depends on orientation)
display_widget (QWidget): optional argument. If entered, the display
