进度条、等待对话框定义及使用

Progress and wait notes From Forum Nokia Wiki Following code sample shows how you could use progress and wait notes with your applications. Note that only the effected functions are shown here, thus you are expected to copy-paste the functions to your own class definition. With this example StartWaitNoteL() can be used to start showing standard wait dialog, when the progress length can not be estimated, for the progress dialog you need to supply the final value as an argument variable when using StartProgressNoteL()-function. To show the progress with progress dialog you could use UpdateProcessL() to supply the current progress value along side with the progress text. The callback interface function DialogDismissedL() is called not only if user presses cancel button, but also after ProcessFinishedL() is called. Therefore you should cancel any process inside DialogDismissedL() if, and only if, aButtonId equals to the key used to close dialog, in this case EAknSoftkeyCancel.
