+<p>Pointer events are handled by the controls. A control should implement
+the function <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html#%3a%3aCCoeControl%3a%3aHandlePointerEventL%28const%20TPointerEvent%20%26amp%3b%29" format="application/java-archive"><parmname>CCoeControl:HandlePointerEventL()</parmname></xref>  to be
+able to handle pointer events. The <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html#%3a%3aCCoeControl%3a%3aHandlePointerEventL%28const%20TPointerEvent%20%26amp%3b%29" format="application/java-archive"><parmname>CCoeControl:HandlePointerEventL()</parmname></xref> function
+is called by the framework whenever a pointer event occurs within the control. </p>
+<codeblock id="GUID-F12E88CC-31FF-4C26-8FEC-0BC2C7717907" xml:space="preserve">virtual void HandlePointerEventL(const TPointerEvent&amp; aPointerEvent)
+</codeblock>
+<p>Before passing pointer events to controls, the framework does some processing
+for the event. If a <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Window_Server/TPointerEventStruct.html#%3a%3aTPointerEvent%3a%3aEButton1Down" format="application/java-archive"><parmname>TPointerEvent::EButton1Down</parmname></xref> event occurred in the control and the control does not currently
+have keyboard focus, it sends an event of type <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/MCoeControlObserverClass.html#%3a%3aMCoeControlObserver%3a%3aEEventRequestFocus" format="application/java-archive"><parmname>MCoeControlObserver::EEventRequestFocus</parmname></xref> to the control's
+observer — normally the control's container. The container control should
+then set focus onto the control in which the <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Window_Server/TPointerEventStruct.html#%3a%3aTPointerEvent%3a%3aEButton1Down" format="application/java-archive"><parmname>TPointerEvent::EButton1Down</parmname></xref> event occurred. </p>
+<p>Note that, by default, pointer drag events and pointer move events are
+not delivered to controls. For additional information, see functions <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Window_Server/RWindowBaseClass.html#%3a%3aRWindowBase%3a%3aPointerFilter%28TUint32%2cTUint32%29" format="application/java-archive"><parmname>RWindowBase::PointerFilter()</parmname></xref> and <xref href="jar:GUID-35228542-8C95-4849-A73F-2B4F082F0C44.jar!/sdk/doc_source/reference/reference-cpp/Control_Environment/CCoeControlClass.html#%3a%3aCCoeControl%3a%3aClaimPointerGrab%28TBool%29" format="application/java-archive"><parmname>CCoeControl::ClaimPointerGrab()</parmname></xref>.
