The Common Desktop Environment: Style Guide and Certification Checklist provides application design style guidelines and the list of requirements for Common Desktop Environment application-level certification. Common Desktop Environment requirements consist of the OSF/Motif Version 1.2 requirements with Common Desktop Environment-specific additions.

The checklist describes keys using a model keyboard mechanism. Wherever keyboard input is specified, the keys are indicated by the engravings on the OSF/Motif model keyboard. Mouse buttons are described using a virtual button mechanism to better describe behavior independent from the number of buttons on the mouse.

## Who Should Use This Book

This book provides information to assist the application designer in developing consistent applications and behaviors within the applications.

## Before You Read This Book

As you compare the behavior of your application to the requirements in this checklist, you may want to consult the OSF/Motif Style Guide (Revision 1.2) for additional style considerations.

By default, this checklist assumes that your application is being designed for a left-to-right language environment in an English-language locale. Some sections of the checklist may require appropriate changes for other locales.

The Style Guide Part of the book refers to checklist items in Chapter 10. Each checklist item is labeled with numbers or letters. The numbered items correspond to the checklist items from the OSF/Motif Style Guide, Revision 1.2 . The Common Desktop Environment-specific additions are labeled with alphabetic identifiers. The checklist items references are followed by the page number where the checklist item appears.
