+in Touch UI</title><p>In touch devices based on the Symbian platform,
+scrollbars (vertical and horizontal) have a touch-enabled scroll box. The
+hardware keys (Arrow keys) can also be used for scrolling when the scrollbars
+are visible. The scrolling movement on the screen is smooth.</p><p>In order
+for the scrollbar to be more usable with touch, the actual scrollbar area
+is wider than the visible scrollbar. When the user scrolls, the scrollbar
+has a related effect to indicate the scrolling. Because the actual area of
+scrollbar is wider, the items appearing on that area in scrollable list, grids,
+viewers etc. cannot be touch-enabled, e.g. list icons in column D cannot be
+tapped.</p></section>
+<section id="GUID-87093F25-CFC3-4D71-A5EF-006C6425C65D"><title>Using
+scrollbars in C++ applications</title><p>The API to use for creating the scrollbar
+component is the Scroller
+API.</p><p>To use a scrollbar in your application, first create a scrollbar
+frame using the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCEikScrollBarFrame.html" format="application/java-archive"><codeph>CEikScrollbarFrame</codeph></xref>. All scrollbar operations are executed via this scrollbar frame.
+These operations include creating and destroying the scrollbar, setting its
+visibility, and adjusting the scrollbar's model. The scrollbar itself can
+be created using the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCEikScrollBarFrame.html#81980f8db36253fc89fb7ebbfa316b4d" format="application/java-archive"><codeph>CreateDoubleSpanScrollBarsL()</codeph></xref> in the class <codeph>CEikScrollBarFrame</codeph>.
+The class for the scrollbar is <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCAknDoubleSpanScrollBar.html" format="application/java-archive"><codeph>CAknDoubleSpanScrollBar</codeph></xref>. For implementation information, see Creating
+a scrollbar.</p><p>Scrollbar models encapsulate the range of integers
+which a scrollbar can represent, from zero to n, and the current position
+of the scrollbar thumb within that range. To set the scrollbar model, use
+the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classTAknDoubleSpanScrollBarModel.html" format="application/java-archive"><codeph>TAknDoubleSpanScrollbarModel</codeph></xref>. For information on updating the scrollbar's position and size using
+the scrollbar model, see Updating
+ArrowHead scrollbar attributes and Updating
+DoubleSpan scrollbar attributes.</p><p>You can control the scrollbar
+visibility using the method <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCEikScrollBarFrame.html#63d2cba6f1261f9c56dd7a98499fceda" format="application/java-archive"><codeph>SetScrollbarVisibilityL()</codeph></xref> in the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classCEikScrollBarFrame.html" format="application/java-archive"><codeph>CEikScrollbarFrame</codeph></xref>.</p><p>To observed scrollbar events,
+use the class <xref href="jar:GUID-759FBC7F-5384-4487-8457-A8D4B76F6AA6.jar!/html/classMEikScrollBarObserver.html" format="application/java-archive"><codeph>MEikScrollbarObserver</codeph></xref>. For implementation information, see Observing
