//! 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)
//! 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
//! allow idgets have been removed, the size group will be freed.
//! 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
//! int mode
//! The directions in which the size group effects the requested sizes of
//! its componenent widgets.
void create(int mode);
//! Create a new group.
void set_mode(int mode);
//! Sets the mode of the size group. One of CONST(GTK_SIZE_GROUP_). The mode
//! of the size group determines whether the widgets in the size group should
//! all have the same horizontal requisition, all have the same vertical
//! requisition, or should all have the same requisition in both directions.
//! Gets the current mode.
void 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.
void remove_widget(GTK2.Widget widget);
//! Removes a widget.
