Description & Source Code

The border layout divides its container into 5 areas: north, west, south, east, and center.

The borders may set to be "splittable" and "collapsable". A splittable border may be dragged to adjust its range, which in turn is confined by its maximum and minimum size. A collapsable border allows users to completely show and hide its bounded area.
