BoxLayout

open class BoxLayout(pointer: <Error class: unknown class><<Error class: unknown class>>) : LayoutManager, Orientable

GtkBoxLayout is a layout manager that arranges children in a single row or column.

Whether it is a row or column depends on the value of its property@Gtk.Orientable:orientation property. Within the other dimension all children all allocated the same size. The GtkBoxLayout will respect the property@Gtk.Widget:halign and property@Gtk.Widget:valign properties of each child widget.

If you want all children to be assigned the same size, you can use the property@Gtk.BoxLayout:homogeneous property.

If you want to specify the amount of space placed between each child, you can use the property@Gtk.BoxLayout:spacing property.
