<section id="GUID-61BDB896-12F1-43D1-B4DD-65BB42911AB6"><p>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. </p></section>

<section id="GUID-6A2B479D-A60D-4153-9221-7771F38B4A92"><title>Using

warning notes in C++ applications</title><p>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 <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>To use a warning

note with the default icon, text, sound, and duration, create an instance

of the note class <xref href="GUID-D4F6D7BE-8C61-3FE7-88B0-FEBDF57BFE0D.dita"><apiname>CAknWarningNote</apiname></xref>. </p><p>To create a global

warning note, use the class <xref href="GUID-2FF927BE-12D6-35E9-8466-011C252E5A66.dita"><apiname>CAknGlobalNote</apiname></xref> in the <xref format="html" href="specs/guides/Notifiers_API_Specification/Notifiers_API_Specification.html" scope="peer">Notifiers API</xref>.

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 <xref href="GUID-267BF374-66FD-3B7F-A56B-2A9689AEA35E.dita"><apiname>CAknNoteDialog</apiname></xref>: <codeph>SetIconL()</codeph>,<codeph>SetTextL()</codeph>, <codeph>SetTone()</codeph> and <codeph>SetTimeout()</codeph>.</p><p>For information on customizing global notes, see <xref format="html" href="specs/guides/Notifiers_API_Specification/Notifiers_API_Specification.html#Notifiers_API_Specification.topic3.4" scope="peer">Enhancing global notes</xref>. You can change the

graphic, animation, tone, and softkeys using the methods in the class <xref href="GUID-2FF927BE-12D6-35E9-8466-011C252E5A66.dita"><apiname>CAknGlobalNote</apiname></xref>: <codeph>SetGraphic()</codeph>, <codeph>SetAnimation()</codeph>, <codeph>SetTone()</codeph>, and <codeph>SetSoftkeys()</codeph>.</p></section>
