              SpaceWidget

A canvas widget that takes up space but does not display anything. SpaceWidgets can be used to add space between elements. Each space widget is characterized by a width and a height. If you wish to only create horizontal space, then use a height of zero; and if you wish to only create vertical space, use a width of zero.
