layout

public void layout(DisplayDimensions dims)

Description copied from interface: Resizable

Called when a change to the class' dimensions is made. This method is responsible for cascading calls to update for any logical children of this class, for example the Plot class is responsible for updating the LayoutManager. Note that while dims is marked final in this interface, the compiler will not enforce it. Implementors of this method should take care not to make changes to dims as this will affect parent Resizables in likely undesired ways.

Specified by:
