OpenSwing Components

4. Layout of framework classes

OpenSwing is a modular framework and its components are distributed in several packages; OpenSwing classes are positioned in three possibile folders, according to the software layer: “client” folder for presentation layer, “server” folder for server-side layer and “java” folder for classes used in both software layers.

In the following table are reported the list of packages in “ org.openswing.swing ” that compose the framework and a syntethic description of classes inside them.
