This is /// typically useful when you want a column of widgets to have the same /// size, but you can’t use a [`Grid`][crate::Grid] widget. /// /// In detail, the size requested for each widget in a [`SizeGroup`][crate::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 [`SizeGroupExt::set_mode()`][crate::prelude::SizeGroupExt::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 [`SizeGroup`][crate::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. /// /// [`SizeGroup`][crate::SizeGroup] objects are referenced by each widget in the size group, /// so once you have added all widgets to a [`SizeGroup`][crate::SizeGroup], you can drop /// the initial reference to the size group with `g_object_unref()`. If the /// widgets in the size group are subsequently destroyed, then they will /// be removed from the size group and drop their references on the size /// group; when all widgets 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 [`SizeGroupMode::Horizontal`][crate::SizeGroupMode::Horizontal] or [`SizeGroupMode::Both`][crate::SizeGroupMode::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 /// [`SizeGroupMode::Vertical`][crate::SizeGroupMode::Vertical] or [`SizeGroupMode::Both`][crate::SizeGroupMode::Both]. /// /// Note that only non-contextual sizes of every widget are ever consulted /// by size groups (since size groups have no knowledge of what size a widget /// will be allocated in one dimension, it cannot derive how much height /// a widget will receive for a given width). When grouping widgets that /// trade height for width in mode [`SizeGroupMode::Vertical`][crate::SizeGroupMode::Vertical] or [`SizeGroupMode::Both`][crate::SizeGroupMode::Both]: /// the height for the minimum width will be the requested height for all /// widgets in the group. The same is of course true when horizontally grouping /// width for height widgets. /// /// Widgets that trade height-for-width should set a reasonably large minimum width /// by way of `property::Label::width-chars` for instance. Widgets with static sizes as well /// as widgets that grow (such as ellipsizing text) need no such considerations. /// /// # GtkSizeGroup as GtkBuildable /// /// Size groups can be specified in a UI definition by placing an `<object>` /// element with `class="GtkSizeGroup"` somewhere in the UI definition. The /// widgets that belong to the size group are specified by a `<widgets>` element /// that may contain multiple `<widget>` elements, one for each member of the /// size group.
