Common Desktop Environment: Style Guide and Certification Checklist








If your application uses a selection box, it is composed of at least a text component for the selected alternative and a list component above the text component for presenting alternatives. The list uses either the single selection or browse selection model. Selecting an element from the list places the selected element in the text component.  

This specification ensures the consistent appearance and operation of a selection box across applications. 



The list navigation actions Up Arrow, Down Arrow, Control+Begin, and Control+End are available from the text component for moving the cursored element within the list and thus changing the contents of the text.  

These actions provide a convenient way to choose an element from the list while focus remains in the text component.
