I am trying to figure out how to make a dynamic component (as a subcomponent of another dynamic component) automatically resize to fill the space between its nearest neighboring components.

If I specifically know the name of the nearest components (left, right, up, down, forward, back) I can make a dynamic component (or dynamic sub component rather) expand/resize to one or more surrounding objects when placed in the space. For this project, the identification of the nearest component would vary, so I'm not sure how to go about sizing the components.

As a basic example, a box represents a space. A divider is added in the north/south direction. Another divider is added in the east/west direction, in the space to the west of the first divider. The first object is automatically resized in length and depth to fit inside the box. The second divider is automatically resized in length to fit between the first divider and the side of the box.

Does anyone know how to go about this? Does it require a ruby script? Any examples? Any help is appreciated.
