Connectors - a framework for building graphical applications in Squeak

Connectors is a framework for building structured drawing editors using Squeak. The rich component library provided with Connectors makes it easy to customize shapes and connectors, in many cases without writing any code. This paper describes how Connectors can be used to quickly construct a Squeak application for editing and visualizing structured data. It describes the entire process of developing a simple Connectors application, including customizing connectors, connection policy, shapes, toolbars, flaps, and worlds. Integration with the Genie gesture recognition system and the eToy tile scripting system is also described.
