Introduction

This tutorial discusses user interface aspects, such as interface components and their appearance and behavior, validation, layout, etc.

In the discussion of interface components we sometimes found it difficult to keep logical interface components separate from toolkit interface components. For example, a label is a logical interface component that describes another component. However, a label is also a toolkit interface component that is used to display non-interactive text and graphics. As such, a label may by used for other functions besides describing other components. For example, a label may be used to create a section header or to display some icons. Wherever possible, we tried to make the distinction between logical and toolkit interface component explicit.
