Communicator UI: 1 FoamSubApplicationClass

Applications may be written to be incorporated into the Nokia 9000i Communicator as part of a special release. The Nokia 9000i Communicator does not have a file manager, per se, to enable launching these applications. The applications must be launched through a currently existing application. FoamSubApplicationClass allows you to indicate under which pre-existing application the new application should reside.

"Add-on" applications for the Nokia 9000i Communicator device, whether included on the device as part of a value-added release, or developed as an aftermarket product, will fall into one of three categories:

Service applications that communicate to the outside world.
System applications that perform a system function. (PC connectivity tools fall under this category, for example.)
"Extra" applications that don't fall into either of the two prior cases.

For each of these cases, there is an application already on the device that launches the sub-application. Service applications are launched using the SVCAPPS launcher; system applications use the SYSAPPS launcher; extra applications use the EXTRAPPS launcher.

Add-on applications are declared using the FoamSubApplication object, and an instance data field is set within the object indicating the "main" application it should be tied with.

Because a sub-application is not a separate application, special care needs to be taken when the sub-application is closed. This is discussed in Using a FoamSubApplication Object .
