CHAPTER 16
Find
Using the Find Service 16-9
Figure 16-9 The ShowFoundItem method displays the view of an overview item
The Find overview provides Routing and Filing buttons. If you are using the
ROM_SoupFinder the system will file, move, and delete your entries in
the overview of found items. In such an occurrence, the soup-change notication
mechanism noties your application. (The soup-change notication mechanism is
described in Chapter 11, “Data Storage and Retrieval.”)
If you are using the
ROM_CompatibleFinder you may either not allow your
found item to be routed or override the relevant methods.
Note that if the system routes your soup-based data, your application is notied via
the soup-change notication mechanism. For a complete description of this
mechanism, see Chapter 11, “Data Storage and Retrieval.
Global and Selected Finds 16
When the user taps the Find button, the system invokes nd methods in the
appropriate applications. For a Local nd, only the currently active application is
sent a message. For a Global nd, all applications registered with the Find service
are sent messages. Selected nds send messages to a user-specied subset of all
applications registered for Global nds. In terms of the messages sent, Global nds
and Selected nds are similar to Local nds; however, there are some differences in
these operations that your application needs to address.
