45 * Base class which handles the dialog and expiration timer. |

46 * Expiration timer can be used to ensure that if the user doesn't handle |
|
47 * a dialog in certain time the dialog is closed. NOTE: In current |
|
48 * implementation the timer is not started, i.e. dialogs never expire. |
|
49 * Implementations of this class should notify a result handler |
|
50 * when dialog result is available. This base class takes care of |
|
51 * notifying possible timeout with KErrTimedOut. |
