For example if you have a QVariant::String type, a <a href="qlineedit.html">QLineEdit</a> would be the default editor returned, whereas a QVariant::Int's default editor would be a <a href="qspinbox.html">QSpinBox</a>. <p> If you want to create different editors for fields with the same data type, subclass QEditorFactory and reimplement the createEditor() function. <p>See also <a href="database.html">Database Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="QEditorFactory"></a>QEditorFactory::QEditorFactory ( <a href="qobject.html">QObject</a> * parent = 0, const char * name = 0 ) </h3> Constructs an editor factory with parent <em>parent</em>, called <em>name</em>. <h3 class=fn><a name="~QEditorFactory"></a>QEditorFactory::~QEditorFactory () </h3> Destroys the object and frees any allocated resources. <h3 class=fn><a href="qwidget.html">QWidget</a> * <a name="createEditor"></a>QEditorFactory::createEditor ( <a href="qwidget.html">QWidget</a> * parent, const <a href="qvariant.html">QVariant</a> & v )<tt> [virtual]</tt> </h3> Creates and returns the appropriate editor for the <a href="qvariant.html">QVariant</a> <em>v</em>.
