PARTS Workbench
Visual Smalltalk Enterprise usually comes with another sub-system called the PARTS Workbench. This system allows the layout of components, which can then be connected using a visual representation of event-message links. Programmers can add scripts to particular components and build nested-components. They can also enhance the functionality of the main VSE Smalltalk system and use that within the PARTS Workbench.
Although the PARTS Workbench allows very easy development of small systems (somewhat after the style of Visual Basic) it is argued that it encourages fragmentary development. The natural style of using this system tends to lead to lots of links and scripts - it is not based around the idea of 'model' (as used in 'Model–View–Controller' approaches common in many Smalltalks as well as in other languages). However, as an 'HCI' for programmers, the PARTS Workbench has many features that are not in modern Smalltalks. It has an immediacy that makes it very good for introductory teaching and for rapidly implementing programs with visual interfaces.

Famous quotes containing the word parts:
“Water, earth, air, fire, and the other parts of this structure of mine are no more instruments of your life than instruments of your death. Why do you fear your last day? It contributes no more to your death than each of the others. The last step does not cause the fatigue, but reveals it. All days travel toward death, the last one reaches it.”
—Michel de Montaigne (1533–1592)
