CHAPTER 2
Container Views
Auxiliary Views 2-15
An auxiliary view appears in front of the view to which it is subordinate. For
details on the customary position of a slip and the front-to-back ordering of
views, “How Views Work” on page 2-28.
Slips 2The most common type of auxiliary view is called a slip. An application can
use slips to get detailed user input. For example, the Date Book application
displays essential information about meetings and events in its main view
but has users input or change details in meeting and event slips. In addition,
an application can use slips to display and allow users to change incidental
and infrequently accessed information such as the title of an item or preference
settings. Slips can also request responses and present alternatives that specify
how an action should be completed. For example, a slip for routing e-mail
should insist the user enter an e-mail address, without which the e-mail
cannot be sent, and the slip offers numerous options that affect what the
e-mail message includes.
Most slips are movable, but some are stationary. Movable slips provide more
flexibility for someone using your application. If a user wants to see something
under a movable slip while the slip is open, the user can drag the slip out of
the way. To see something under a stationary slip, a user has no choice but to
close the slip. Figure 2-14 compares slips that move with slips that can’t.
