Visual Programming User Guide : Introduction to Visual Programming
Introduction to Visual Programming
The following sections build upon what you learned in Getting Started about the VA Smalltalk development environment and the tools available to help you build applications visually from parts or textually as Smalltalk code.
These sections further explore the visual programming paradigm and its set of tools: the Composition Editor, the Script Editor and the Public Interface Editor.
Simple examples introduce you to the routine capability of these tools:
•Adding scripts introduces you to the Script Editor and how to connect the script to your part in the Composistion Editor.
•Creating reusable parts introduces you to the Public Interface Editor through the Road Race example.
•Using nonvisual parts teaches you to to pass information between parts in the Road Race example.
•Validating user input explores how to ensure an address you input contains valid data.
Adding help to your application extends the Investment application developed in Getting Started.
Debugging your application digs into the capability of the Composition Editor to illuminate what exactly is happening in the scripts and connections of your application
