This is typically useful when you want a column of widgets to have the same size, but you can't use a GtkTable widget.
In detail, the size requested for each widget in a GtkSizeGroup 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
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 GtkSizeGroup 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

GtkSizeGroup objects are referenced by each widget in the size group,
so once you have added all widgets to a GtkSizeGroup, you can drop
the initial reference to the size group with
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 GtkSizeGroup as GtkBuildable
Size groups can be specified in a UI definition by placing an
<object> element with Example 46. A UI definition fragment with GtkSizeGroup <object class="GtkSizeGroup"> <property name="mode">GTK_SIZE_GROUP_HORIZONTAL</property> <widgets> <widget name="radio1"/> <widget name="radio2"/> </widgets> </object> Detailsenum GtkSizeGroupModetypedef enum { GTK_SIZE_GROUP_NONE, GTK_SIZE_GROUP_HORIZONTAL, GTK_SIZE_GROUP_VERTICAL, GTK_SIZE_GROUP_BOTH } GtkSizeGroupMode; The mode of the size group determines the directions in which the size group affects the requested sizes of its component widgets.
gtk_size_group_new ()GtkSizeGroup* gtk_size_group_new (GtkSizeGroupMode mode); Create a new GtkSizeGroup.
gtk_size_group_set_mode ()void gtk_size_group_set_mode (GtkSizeGroup *size_group, GtkSizeGroupMode mode);
Sets the GtkSizeGroupMode of the size group. The mode of the size
group determines whether the widgets in the size group should
all have the same horizontal requisition (
gtk_size_group_get_mode ()GtkSizeGroupMode gtk_size_group_get_mode (GtkSizeGroup *size_group);
Gets the current mode of the size group. See
gtk_size_group_set_ignore_hidden ()void gtk_size_group_set_ignore_hidden (GtkSizeGroup *size_group, gboolean ignore_hidden); Sets whether unmapped widgets should be ignored when calculating the size.
Since 2.8 gtk_size_group_get_ignore_hidden ()gboolean gtk_size_group_get_ignore_hidden (GtkSizeGroup *size_group); Returns if invisible widgets are ignored when calculating the size.
Since 2.8 gtk_size_group_add_widget ()void gtk_size_group_add_widget (GtkSizeGroup *size_group, GtkWidget *widget);
Adds a widget to a GtkSizeGroup. 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 of the size group. See When the widget is destroyed or no longer referenced elsewhere, it will be removed from the size group.
gtk_size_group_remove_widget ()void gtk_size_group_remove_widget (GtkSizeGroup *size_group, GtkWidget *widget); Removes a widget from a GtkSizeGroup.
gtk_size_group_get_widgets ()GSList* gtk_size_group_get_widgets (GtkSizeGroup *size_group);
Returns the list of widgets associated with
