*
* SizeGroup provides a mechanism for grouping a number of
* widgets together so they all request the same amount of space.
* This is typically useful when you want a column of widgets to
* have the same size, but you can't use a Table widget.
*
* Note that size groups only affect the amount of space requested,
* not the size that the widgets finally receive. If you want the
* widgets in a SizeGroup to actually be the same size, you need
* to pack them in such a way that they get the size they request
* and not more. For example, if you are packing your widgets
* into a table, you would not include the Gtk.Fill flag.
