An explanation of the concept of document and GUI unified programming interface (depricated)

 
UML class diagram of document and GUI classes - red classes are core classes, blue classes are document and gui classes, and green are GUI classes.
 
The SPTK features both, document and gui based applications. These types of applications are compatible to each other in some ways. Any document based application can be used within a gui because the gui plugins support the full document commands.
 
In the figure at the top of this page you can see which classes are for document use (colored blue) and which are for GUI use (colored blue and green). If you want to implement an own document or GUI plugin you have to support all so colored classes as childs in your plugin. The red classes are the base classes for SPTK applications and are only located in the SPTKcore. They don't have childs in the Plugins.
 
The development of own plugins and their concept are explained in an own document soon.
