Form Editor - BoxLayout - Horizontal

Form Editor - BoxLayout - Vertical

The BoxLayout lines up controls horizontally or vertically.

BoxLayout takes the space it gets (from its parent layout or from the parent control), divides it up into a row of boxes, and makes each managed control fill one box.
