public class SizeGroup extends GObject
In detail, the size requested for each widget in a SizeGroup is the maximum of the sizes that would have been requested for each widget in the size group if they were not in the size group. The mode of the size group (see {@link #setMode(SizeGroupMode)} determines whether this applies to the horizontal size, the vertical size, or both sizes.
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.
Widgets can be part of multiple size groups; GTK+ will compute the horizontal size of a widget from the horizontal requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK_SIZE_GROUP_HORIZONTAL or GTK_SIZE_GROUP_BOTH, and the vertical size from the vertical requisition of all widgets that can be reached from the widget by a chain of size groups of type GTK_SIZE_GROUP_VERTICAL or GTK_SIZE_GROUP_BOTH.
