<h2>Detailed Description</h2>
<p>The Q3SqlEditorFactory class is used to create the editors used by <a href="q3datatable.html">Q3DataTable</a> and <a href="q3sqlform.html">Q3SqlForm</a>.</p>
<p>Q3SqlEditorFactory is used by <a href="q3datatable.html">Q3DataTable</a> and <a href="q3sqlform.html">Q3SqlForm</a> to automatically create appropriate editors for a given <a href="qsqlfield.html">QSqlField</a>. For example if the field is a <a href="qvariant.html#Type-enum">QVariant::String</a> a <a href="qlineedit.html">QLineEdit</a> would be the default editor, whereas a <a href="qvariant.html#Type-enum">QVariant::Int</a>'s default editor would be a <a href="qspinbox.html">QSpinBox</a>.</p>
<p>If you want to create different editors for fields with the same data type, subclass Q3SqlEditorFactory and reimplement the <a href="q3sqleditorfactory.html#createEditor">createEditor</a>() function.</p>
<p>See also <a href="q3datatable.html">Q3DataTable</a> and <a href="q3sqlform.html">Q3SqlForm</a>.</p>

<h3 class="fn"><a name="Q3SqlEditorFactory"></a>Q3SqlEditorFactory::Q3SqlEditorFactory ( <a href="qobject.html">QObject</a> * <i>parent</i> = 0 )</h3>
<p>Constructs a SQL editor factory with parent <i>parent</i>.</p>
<a name="//apple_ref/cpp/instm/Q3SqlEditorFactory/~Q3SqlEditorFactory"></a>
<h3 class="fn"><a name="dtor.Q3SqlEditorFactory"></a>Q3SqlEditorFactory::~Q3SqlEditorFactory ()</h3>
<p>Destroys the object and frees any allocated resources.</p>
<a name="//apple_ref/cpp/instm/Q3SqlEditorFactory/createEditor"></a>
<h3 class="fn"><a name="createEditor"></a><a href="qwidget.html">QWidget</a> * Q3SqlEditorFactory::createEditor ( <a href="qwidget.html">QWidget</a> * <i>parent</i>, const <a href="qvariant.html">QVariant</a> & <i>variant</i> ) <tt> [virtual]</tt></h3>
<p>Reimplemented from <a href="q3editorfactory.html#createEditor">Q3EditorFactory::createEditor</a>().</p>
<p>Creates and returns the appropriate editor widget for the <a href="qvariant.html">QVariant</a> <i>variant</i>.</p>
<p>The widget that is returned has the parent <i>parent</i> (which may be zero). If <i>variant</i> is invalid, 0 is returned.</p>

<p>This is an overloaded function.</p>
<p>Creates and returns the appropriate editor for the <a href="qsqlfield.html">QSqlField</a> <i>field</i>.</p>

<h3 class="fn"><a name="installDefaultFactory"></a>void Q3SqlEditorFactory::installDefaultFactory ( Q3SqlEditorFactory * <i>factory</i> ) <tt> [static]</tt></h3>
<p>Replaces the default editor factory with <i>factory</i>. All <a href="q3datatable.html" class="compat">Q3DataTable</a> and <a href="q3sqlform.html" class="compat">Q3SqlForm</a> instantiations will use this new factory for creating field editors. <i><a href="q3sqleditorfactory.html" class="compat">Q3SqlEditorFactory</a> takes ownership of <i>factory</i>, and destroys it when it is no longer needed.</i></p>
