1 Introduction

This booklet is a collection of how-to guides for building basic GUI (Graphic User Interface) with Cuis-Smalltalk and its Morphic system. Some chapters, such as What is a Morph after all? and Design a GUI Application, present deeper knowledge. Most chapters can be read independently to suit the reader’s needs.

The standard Cuis-Smalltalk framework for building user interfaces is Morphic 3; it is the most refined version of the Morphic graphic system found in Smalltalk environments. What non-Smalltalk GUI libraries refer to as components or widgets is called a Morph in Cuis-Smalltalk; therefore, in the rest of this book, the terms Morph, widget, and component are interchangeable.
