<h2>Detailed Description</h2>
<p>The QItemEditorFactory class provides widgets for editing item data in views and delegates.</p>
<p>When editing the data shown by an item delegate, the <a href="qitemdelegate.html">QItemDelegate</a> responsible requests an editor widget from its item editor factory by calling the <a href="qitemeditorfactory.html#createEditor">createEditor</a>() function. The default factory is provided by this class, but it is possible to implement subclasses that provide specialized editing behavior, such as row or column-specific editors, or editors for certain types of data.</p>
<a name="standard-editing-widgets"></a>
<h3>Standard Editing Widgets</h3>
<p>The standard factory implementation provides editors for a variety of data types. These are created whenever a delegate needs to provide an editor for data supplied by a model. The following table shows the relationship between types and the standard editors provided.</p>
<p><table align="center" cellpadding="2" cellspacing="1" border="0">

</table></p>
<p>Additional editors can be registered for use with both standard and custom delegates with the <a href="qitemeditorfactory.html#registerEditor">registerEditor</a>() function.</p>
