williamr@2: /** Intermediate state
williamr@2:  *
williamr@2:  * To implement intermediate states:
williamr@2:  * 1) add iAvkonEnv->RegisterIntermediateState(this) to dialog's ActivateL()
williamr@2:  * 2) add iAvkonEnv->UnRegisterIntermediateState(this) to destructor
williamr@2:  * 3) derive your control from MAknIntermediateState.
williamr@2:  * 4) implement CloseState() method. It should call TryExitL() or something.
williamr@2:  * (NOTE, the method is NOT L-method, so use T_RAPD(err, TryExitL(buttonid));
williamr@2:  *
williamr@2:  * This will cause your intermediate states to close automatically when
williamr@2:  * you swap to another application.
