35  * #GAppInfoMonitor is a very simple object used for monitoring the app
36  * info database for changes (ie: newly installed or removed
37  * applications).
38  * 
39  * Call g_app_info_monitor_get() to get a #GAppInfoMonitor and connect
40  * to the "changed" signal.
41  * 
42  * In the usual case, applications should try to make note of the change
43  * (doing things like invalidating caches) but not act on it.  In
44  * particular, applications should avoid making calls to #GAppInfo APIs
45  * in response to the change signal, deferring these until the time that
46  * the data is actually required.  The exception to this case is when
47  * application information is actually being displayed on the screen
48  * (eg: during a search or when the list of all applications is shown).
49  * The reason for this is that changes to the list of installed
50  * applications often come in groups (like during system updates) and
51  * rescanning the list on every change is pointless and expensive.
