<p>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,<uicontrol>Cancel</uicontrol> is
provided.</p>

     <title>Using wait notes in applications</title>     <p>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 <xref format="html" href="specs/guides/Notes_API_Specification/Notes_API_Specification.html" scope="peer">Notes API</xref> (for basic notes) and the <xref format="html" href="specs/guides/Notifiers_API_Specification/Notifiers_API_Specification.html" scope="peer">Notifiers API</xref> (for global notes). </p><p>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 <xref format="html" href="specs/guides/Notes_API_Specification/Notes_API_Specification.html#Notes_API_Specification.topic3.3" scope="peer">Creating a wait note</xref>.</p><p>To create a global wait note,

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 <xref href="GUID-267BF374-66FD-3B7F-A56B-2A9689AEA35E.dita"><apiname>CAknNoteDialog</apiname></xref> class: <ul>
