-area registry based feedback</title><prolog><metadata><keywords/></metadata></prolog><conbody>
-<p>To use area registry based feedback, you must usually first call <codeph>MTouchFeedback::Instance</codeph> (unless
-you get a reference to it via another class).</p>
-<p>It is recommended that you store the returned pointer as a member variable
-in those places where it is needed frequently. This is because the pointer
-is fetched from thread local storage, which can be somewhat time-consuming. </p>
-<p>To add feedback areas to the area registry, use the <codeph>SetFeedbackArea</codeph> function.
-Usually the best place to do this is <codeph>SizeChanged</codeph> function,
-because that is also the place to update feedback areas in case of a layout
-change.</p>
-<note><p>You can also use the same <codeph>SetFeedbackArea</codeph> function
-for updating the feedback area (the API implementation adds the area to the
-registry on the first time, and then just does updates on subsequent calls
-to this function). </p></note>
-<p>If you want to change the feedback area or type without giving all the
-parameters again, use the functions <codeph>ChangeFeedbackArea</codeph> and <codeph>ChangeFeedbackType</codeph> for
-the updates. </p>
-<p>Also notice that you have to be prepared in case your control is moved
-with <codeph>CCoeControl::SetPosition</codeph> function. For this you need
-to override <codeph>CCoeControl::PositionChanged</codeph>, and update the
-feedback area there the same way as in the <codeph>SizeChanged</codeph> function.
-Moreover, notice that this is necessary only for those non-window-owning controls,
-which produce area registry based feedback. </p>
-<p>Feedback areas of a specific control will be automatically disabled in
-case the control becomes dimmed by <codeph>CCoeControl::SetDimmed( ETrue )</codeph> or
-invisible by <codeph>CCoeControl::MakeVisible( EFalse )</codeph>. Feedback
-will be re-enabled again when control becomes both undimmed and visible. This
-functionality is based on using the object provider hierarchy, and thus it
-does not work in case the object provider parent has not been set for the
-control.</p>
-<p> If you need to disable a control’s feedback area temporarily (for other
-reasons than dimming or visibility), call <codeph>EnableFeedbackForControl</codeph> with
-second parameter <codeph>EFalse</codeph> to disable the feedback. You can
-then re-enable feedback by calling <codeph>EnableFeedbackForControl</codeph> with
-second parameter <codeph>ETrue</codeph>. Disabling of control’s feedback also
-affects direct feedback if it is generated with the overloaded version, which
-takes the control’s pointer as the second parameter. </p>
-<p>In some special cases it may be necessary to only disable audio- or vibra
-feedback for some controls. For this purpose there is a specific overload
-of <codeph>EnableFeedbackForControl</codeph> function.</p>
-<p>You must remove your control's feedback areas at the latest when you destroy
-the control. To do this, call the function <codeph>RemoveFeedbackForControl</codeph> .
-This also resets the feedback disabling information for the deleted control.
-If needed, you can remove individual feedback areas with the <codeph>RemoveFeedbackArea</codeph> function
-any time, but you must still call <codeph>RemoveFeedbackForControl</codeph> you
-destroy the control.</p>
-<p>The example below illustrates using tactile feedback based on the area
-registry. </p>
-<ol>
-<li id="GUID-95E49C03-19A2-4E39-BBDE-A907EAC87D3A"><p>Add the library <codeph>touchfeedback.lib</codeph> into
