This is typically -- useful when you want a column of widgets to have the same size, but you -- can't use a Gtk_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 -- Gtk_Size_Group 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 Fill flag. -- </description> -- <c_version>2.8.17</c_version> -- <testgtk>create_size_groups.adb</testgtk> with Glib.Object;
