 * \subsection Sub6 3.6 Constructing and initialising a grid control
 *
 * In this section, the method of construction and initialisation are described.
 *
 * There are two ways to construct the CAknGrid object: 
 *
 * - Construct without resource data 
 * - Construct with resource data 
 *
 * The ConstructL function needs to be called in case resource data is not used. However, the application programmer needs to call setting functions step by step. 
 *
 * The ConstructFromResourceL function needs to be called in case resource data is used.
 *
 * Usually, the CAknGridM class object is instantiated automatically during the construction phase of the CAknGrid object. If an application programmer provides their own grid model class, the application programmer must instantiate their own grid model class object and give it to the CAknGrid object using the SetModel function before calling the ConstructL/ConstructFromResourceL function.
 *
 * After setting model, it is necessary to set icons and items in the grid.
 *
 * \subsection Sub7 3.7 Runtime operation
 *
 * This section describes how to code to operate the grid control.
 *
 * \subsection Sub8 3.7.1 Coding to operate the cursor and grid mark
 *
 * SetCurrentDataIndex is the function to move the grid cursor.
 *
<div align=left><table style="width:65%;" cellspacing="4" width="65%" bgcolor="#DDDDDD" class="hcp27">
<tr>
<td	width=100%>
<p class=CodeInTable>iGrid-&gt;SetCurrentDataIndex(  <i>an 
 index</i>  );<br>
iGrid-&gt;DrawNow();&nbsp; &nbsp; // This method is called to refresh the 
 grid.</td></tr>
</table></div>
 *
 * SelectItemL(set mark), DeSelectItemL (de-select mark) and ToggleItemL(set as reversed) are provided to operate the item mark. The following code is an example of marking the item:
 *
<div align=left><table style="width:65%;" cellspacing="4" width="65%" bgcolor="#DDDDDD" class="hcp27">
<tr>
<td width=100%>
<p class=CodeInTable>iGrid-&gt;View()-&gt;SelectItemL( <i> an index </i> );<br>
iGrid-&gt;DrawNow();&nbsp; &nbsp; // This method is called to refresh the 
 grid.</td></tr>
</table></div>
 *
 * The CurrentDataIndex function gives the  index of the selected item.
 *
<div align=left><table style="width:65%;" cellspacing="4" width="65%" bgcolor="#DDDDDD" class="hcp27">
<tr>
<td width=100%>
<p class=CodeInTable>TInt currentIndex = iGrid-&gt;CurrentDataIndex();</td></tr>
</table></div>
 *
 * The ItemIsSelected function is used to know whether items are marked.
 *
<div align=left><table style="width:65%;" cellspacing="4" width="65%" bgcolor="#DDDDDD" class="hcp27">
<tr>
<td width=100%>
<p class=CodeInTable>TBool isSelected = iGrid-&gt;View()-&gt;ItemIsSelected( 
 <i> an index </i> );</td></tr>
</table></div>
 *
 * \subsection Sub9 3.7.2 Coding to insert and remove items
 *
 * The Model()->SetItemTextArray() function and array are used to insert or remove items. Items are inserted or removed in array, then the HandleItemAdditionL function needs to be called. The following is an example of inserting items:
 *
<div align=left><table style="width:65%;" cellspacing="4" width="65%" bgcolor="#DDDDDD" class="hcp27">
<tr>
<td width=100%>
<p class=CodeInTable>iItemArray-&gt;AppendL(); // iItemArray 
 was set to the grid before using<br>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 // iGrid-&gt;Model()-&gt;SetItemTextArray(iItemArray);<br>
iGrid-&gt;HandleItemAdditionL();&nbsp; // HandleItemAdditionL() must be 
 called<br>
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; 
 // after adding an item.<br>
iGrid-&gt;DrawNow();</td></tr>
</table></div>
 *
 * \subsection Sub10 3.8 Event handling
 *
 * To handle an event for the grid, an event handling architecture for the listbox can be used.
 * To use this: 
 *
 * - The container of the grid should be derived from MEikListBoxObserver. 
 * - Call iGrid->SetListBoxObserver(this) to set an observer to the grid. 
 * - HandleListBoxEventL() must be overridden. 
 *
