This is typically usefull when you want //! a column of widgets to have the same size, but you can't use a W(Table) //! widget. //! <p> //! In detail, the size requiest for each widget in a GTK2.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 set_mode() determines whether this applies to the horizontal size, the //! vertical size, or both sizes. //! <p> //! 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 //! GTK2.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 //! GTK2.FILL flag. //! <p> //! GTK2.SizeGroup objects are referenced by each widget in the size group, so //! one you have added all widgets to a GTK2.SizeGroup, you can drop the initial //! reference to the size group. If the widgets in the size group are //! subsequently destroyed, then they will be removed from the size group; when
a5c24c2016-07-07Chris Angelico //! all widgets have been removed, the size group will be freed.
1a05542005-07-28Martin Nilsson //! <p> //! 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 //! GTK2.SIZE_GROUP_HORIZONTAL or GTK2.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 GTK2.SIZE_GROUP_VERTICAL or //! GTK2.SIZE_GROUP_BOTH. //! Properties: //! int mode //! The directions in which the size group effects the requested sizes of //! its componenent widgets.
