A Box is a rectangular area organized into either a single row or a single column of child widgets, depending upon whether the box is horizontally or vertically oriented, respectively.
Widgets that are 'packed' into a box are considered to be the children of the box, and the box controls their layout. Properties such as . control the layout of all the children in the box, whereas specific packing settings can be applied to each child individually, such as .(Widget, bool, bool, uint, PackType).
