Warning +note

Warning +notes are used when the user must be notified about something that may require +action. They have a fairly long duration, and a sound that can be heard (and +distinguished) even when not concentrating on the phone. For example, the +battery low warning.

Using +warning notes in C++ applications

You can create either a basic +warning note that is displayed only when your application is in the foreground +or a global note that stays displayed even if the application launching the +note is not in the foreground. The related APIs are the Notes +API (for basic notes) and the Notifiers API (for global notes).

To use a warning +note with the default icon, text, sound, and duration, create an instance +of the note class CAknWarningNote.

To create a global +warning note, use the class CAknGlobalNote in the Notifiers API. For implementation information, see Using global notes and Using global notes with user interaction.

For basic +notes, you can change the icon or text displayed in the note, use a different +kind of sound, or change the note duration using the setter methods in the +class CAknNoteDialog: SetIconL(),SetTextL(), SetTone() and SetTimeout().

For information on customizing global notes, see Enhancing global notes. You can change the +graphic, animation, tone, and softkeys using the methods in the class CAknGlobalNote: SetGraphic(), SetAnimation(), SetTone(), and SetSoftkeys().
