I remember going to a developer converence for Java and seeing a library
which had a special layout manager that allowed relativly layout of
components. They used "shocks, struts, and beams" to specify forces which
created final positions of layers. Using that concept, I came up with a
layout manager design which allowed the designer to specify, relative to any
side of the layer bounding box, the position of another layer. When
specifying a "force" the first layer is considered the anchor which the
other is placed relative.
Using shocks (or springs): the space between 2 objects had a minimum
distance, but no max. The objects would move to the max distance allowed
relative to any other force acting upon it.
Using struts: There is no minimum space greater than zero. But there is a
maximum distance that they can go. (Like an inverse spring) The objects
would move as close to each other relative to other forces.
Using beams: There is a specific distance between them. No more, no less.
Positions where specified with a vector. Distance: D and Angle: T
Ok... someone write it!
