31322b2006-01-05Marcus Comstedt //! Provides a mechanism for grouping a number of widgets together so they all //! request the same amount of space. 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. //! //! 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. //! //! 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. //! //! 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

31322b2006-01-05Marcus Comstedt //! //! 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. //! //! inherit G.Object; GTK2.SizeGroup add_widget( GTK2.Widget widget ); //! Adds a widget to the group. In the future, the requisition of the widget //! will be determined as the maximum of its requisition and the requisition //! of the other widgets in the size group. Whether this applies horizontally, //! vertically, or in both directions depends on the mode. //! //!
