<p>The principal uses of the Navi pane are to display information about the
current state and view, and to help the user to navigate in the application.</p>

<p>Depending on the context, the Navi pane contains elements presented in

<entry><p>Tabs are used to view parallel data views alternatively. Arrow indicators
are shown at both ends of the pane when there are further tabs to scroll in
the corresponding direction. Each tab has either a graphic or a text (or both)
as a label. The following tab layouts can be used: <ul>
<li><p>Two tabs</p></li>
<li> <p>Three tabs</p></li>
<li><p>Four tabs</p></li>
<li><p>Two long tabs</p></li>
<li> <p>Three long tabs (stacked so that only one is fully visible at a time)</p></li>
</ul>The currently active tab is highlighted.</p><p>More than four tabs can
exist simultaneously. They can be scrolled horizontally. However, as a design
guideline, the number of tabs should be kept small (the maximum of six tabs
is recommended), and the number should not be dynamic. See <xref href="GUID-72DE3EB1-1AF5-4157-8B99-A1C7143DAD2C.dita"/> for
a description of the effect of tabs on the navigation within an application.</p></entry>

C++ applications</title><p>The API to use for the Navi pane is the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/Navigation_Pane_APIIndexPage.html" format="application/java-archive">Navigation pane API</xref>. If you use tabs in the Navi pane, the API for
controlling the tabs is the <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/Tabs_APIIndexPage.html" format="application/java-archive">Tabs

the observer, use the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknNavigationDecorator.html#660e9ba08945b213aba477b7863873cc" format="application/java-archive"><codeph>CAknNavigationDecorator::SetNaviDecoratorObserver()</codeph></xref>.</p><p>To
create a tab group in the Navi pane, use the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknNavigationControlContainer.html#93d16329080f21bcd8428db61f177abc" format="application/java-archive"><codeph>CreateTabGroupL()</codeph></xref> in the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknNavigationControlContainer.html" format="application/java-archive"><codeph>CAknNavigationControlContainer</codeph></xref>. This is a factory
method for a pre-implemented navigation pane tab group control.</p></section>
