Container Views
2-40 How Views Work
Figure 2-32 How scroll arrows work in the Date Book’s Day view
Usually each tap on a local scroll arrow scrolls one item of information. If
a user presses and holds the pen on a local scroll arrow, items scroll by
continuously. After five items have scrolled by, the application can begin
scrolling page by page. For scrolling purposes, the size of a page is one less
than the number of items that fit in the view. As a shortcut, a user can double-
tap a local scroll arrow to scroll a page. These two forms of accelerated
scrolling are optional, but an application that features accelerated scrolling
should behave as described here.
A view can contain local scroll arrows even if it does not respond to the
universal scroll arrows. The local scroll arrows shouldn’t scroll the whole
view; they should only scroll some part of the view.
