Wait notes contain a wait graphic of indefinite duration. They are used during operations that take a long time when it is not possible to estimate the duration of the operation. Whenever possible, the user should be able to stop the operation. For this, a softkey labeled for example,Cancel is provided.
You can create either a basic wait 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).
Wait notes are predefined notes that cannot be used just by instantiating a simple note class. These notes' lifetime is based on a background process, and client code has to provide an interface to retrieve this information. For implementation information, see Creating a wait note.
To create a global wait note, use the CAknGlobalNote class in the Notifiers API. For implementation information, see Using global notes and Using global notes with user interaction.
