    21 /** Intermediate state

    22  *

    23  * To implement intermediate states:

    24  * 1) add iAvkonEnv->RegisterIntermediateState(this) to dialog's ActivateL()

    25  * 2) add iAvkonEnv->UnRegisterIntermediateState(this) to destructor

    26  * 3) derive your control from MAknIntermediateState.

    27  * 4) implement CloseState() method. It should call TryExitL() or something.

    28  * (NOTE, the method is NOT L-method, so use T_RAPD(err, TryExitL(buttonid));

    29  *

    30  * This will cause your intermediate states to close automatically when

    31  * you swap to another application.
