 * \subsection Sub332 3.3.2 Event handling for the listbox
 *
 * When the listbox receives a key event, it calls HandleListBoxEventL in MeikListBoxObserver directly.
 *
 * \subsection Sub333 3.3.3 Resource definition of listbox classes
 * 
 * To define resources for the listbox, the resource structure LISTBOX is used.

<td style="width: 100%;"
	width=100%><i><span class="hcp20">Example</span></i></td></tr>

 * \subsection Sub334 3.3.4 Using resource data
 *
 * The following is an example of using resource data.
 *
 * The example of SingleItemListBox.
 * 
<div align=left><table  style="width:60%;" cellspacing="4" width="60%" bgcolor="#DDDDDD" class="hcp21">

<tr>
<td style="width: 100%;"
	width=100%><i><span class="hcp20">Example</span></i></td></tr>

<tr>
<td style="width:100%;" bgcolor="#EEEEEE" width="100%" class="hcp22">
<p class=CodeInTable>resourceId = R_AKNTALIST_SINGLE_1;<br>
CAknSingleStyleListBox* listBox = new(ELeave)CAknSingleStyleListBox();<br>
listBox-&gt;SetContainerWindowL( parent);<br>
TResourceReader reader;<br>
CEikonEnv::Static()-&gt;CreateResourceReaderLC(reader, aResourceId);<br>
listBox-&gt;SetObserver(observer);<br>
listBox-&gt;ConstructFromResourceL( reader );<br>
CleanupStack::PopAndDestroy(); // resource stuffs. </td></tr>
</table>
</div>
 *
 * This is the common code to create control from resource data. To create another type of listbox, simply change CAknSingleStyleListBox.
 *
 * \subsection Sub335 3.3.5 Implementation of the observer handler for the listbox
 *
 * The listbox observer is necessary for all listboxes. A notification of specific actions for the listbox are given to the observer. It is necessary to instantiate an object that is derived from MEikListBoxObserver to control the listbox. After instantiation, SetObserver is called to set the observer to the listbox. Then HandleListBoxEventL of the observer is called when the following events are issued:
 *
<div align=left><table 
		style="width: 70%;
				float: alignleft;
				x-border-left: 1px table-solid;
				x-border-top: 1px table-solid;

				x-border-bottom: 1px table-solid;
				border-collapse: separate;
				border-spacing: 0px;
				x-border-left: 1px table-solid;
				x-border-top: 1px table-solid;

 * \subsection Sub336 3.3.6 Changing the contents of the listbox dynamically
 *
 * The status of the listbox is changeable dynamically with APIs as shown below. To change the contents of the list:
 *
<div align=left><table style="width:70%;" cellspacing="4" width="70%" bgcolor="#DDDDDD" class="hcp21">

<tr>
<td style="width:100%;" bgcolor="#EEEEEE" width="100%" class="hcp22">
<p class=CodeInTable>MListBoxModel* CEikListBox::Model() 
 const<br>
- This function is used for getting the listbox model.<br>
<br>
const MDesCArray* CListBoxNumbersModel::MatchableTextArray() const<br>
- This function must be also used.<br>
&nbsp; Also, functions in the MDesCArray class are available.<br>
These functions are used as shown below:<br>
CEikListBox* listbox;<br>
