A default unique instance provided by QItemEditorFactory is used by all item delegates. If you set a new default factory with <a href="qitemeditorfactory.html#setDefaultFactory">setDefaultFactory</a>(), the new factory will be used by existing and new delegates.</p> <p>A factory keeps a collection of <a href="qitemeditorcreatorbase.html">QItemEditorCreatorBase</a> instances, which are specialized editors that produce editors for one particular <a href="qvariant.html">QVariant</a> data type (All Qt models store their data in <a href="qvariant.html">QVariant</a>s).</p> <a id="standard-editing-widgets" name="standard-editing-widgets" /> <h3>Standard Editing Widgets</h3> <p>The standard factory implementation provides editors for a variety of data types.
