For example if the field is a TQVariant::String a <a href="ntqlineedit.html">TQLineEdit</a> would be the default editor, whereas a TQVariant::Int's default editor would be a <a href="ntqspinbox.html">TQSpinBox</a>. <p> If you want to create different editors for fields with the same data type, subclass TQSqlEditorFactory and reimplement the <a href="#createEditor">createEditor</a>() function. <p> <p>See also <a href="tqdatatable.html">TQDataTable</a>, <a href="tqsqlform.html">TQSqlForm</a>, and <a href="database.html">Database Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="TQSqlEditorFactory"></a>TQSqlEditorFactory::TQSqlEditorFactory ( <a href="tqobject.html">TQObject</a> * parent = 0, const char * name = 0 ) </h3> Constructs a SQL editor factory with parent <em>parent</em>, called <em>name</em>. <h3 class=fn><a name="~TQSqlEditorFactory"></a>TQSqlEditorFactory::~TQSqlEditorFactory () </h3> Destroys the object and frees any allocated resources. <h3 class=fn><a href="tqwidget.html">TQWidget</a> * <a name="createEditor"></a>TQSqlEditorFactory::createEditor ( <a href="tqwidget.html">TQWidget</a> * parent, const <a href="ntqvariant.html">TQVariant</a> & variant )<tt> [virtual]</tt> </h3> Creates and returns the appropriate editor widget for the <a href="ntqvariant.html">TQVariant</a> <em>variant</em>. <p> The widget that is returned has the parent <em>parent</em> (which may be zero).
