<hr><a name="details"></a><h2>Detailed Description</h2>


The TQEditorFactory class is used to create editor widgets
for <a href="tqvariant.html">TQVariant</a> data types.
<p> 

<p> Each editor factory provides the <a href="#createEditor">createEditor</a>() function which
given a TQVariant will create and return a <a href="tqwidget.html">TQWidget</a> that can edit
that TQVariant. For example if you have a TQVariant::String type, a
<a href="tqlineedit.html">TQLineEdit</a> would be the default editor returned, whereas a
TQVariant::Int's default editor would be a <a href="tqspinbox.html">TQSpinBox</a>.
<p> If you want to create different editors for fields with the same
data type, subclass TQEditorFactory 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="TQEditorFactory"></a>TQEditorFactory::TQEditorFactory ( <a href="tqobject.html">TQObject</a>&nbsp;*&nbsp;parent = 0, const&nbsp;char&nbsp;*&nbsp;name = 0 )
</h3>
Constructs an editor factory with parent <em>parent</em>, called <em>name</em>.

<h3 class=fn><a name="~TQEditorFactory"></a>TQEditorFactory::~TQEditorFactory ()
</h3>
Destroys the object and frees any allocated resources.

<h3 class=fn><a href="tqwidget.html">TQWidget</a>&nbsp;* <a name="createEditor"></a>TQEditorFactory::createEditor ( <a href="tqwidget.html">TQWidget</a>&nbsp;*&nbsp;parent, const&nbsp;<a href="tqvariant.html">TQVariant</a>&nbsp;&amp;&nbsp;v )<tt> [virtual]</tt>
</h3>
Creates and returns the appropriate editor for the <a href="tqvariant.html">TQVariant</a> <em>v</em>.
If the TQVariant is invalid, 0 is returned. The <em>parent</em> is passed
to the appropriate editor's constructor.

<p>Reimplemented in <a href="tqsqleditorfactory.html#createEditor">TQSqlEditorFactory</a>.
<h3 class=fn><a href="tqeditorfactory.html">TQEditorFactory</a>&nbsp;* <a name="defaultFactory"></a>TQEditorFactory::defaultFactory ()<tt> [static]</tt>
</h3>
Returns an instance of a default editor factory.

<h3 class=fn>void <a name="installDefaultFactory"></a>TQEditorFactory::installDefaultFactory ( <a href="tqeditorfactory.html">TQEditorFactory</a>&nbsp;*&nbsp;factory )<tt> [static]</tt>
</h3>
Replaces the default editor factory with <em>factory</em>.
<em>TQEditorFactory takes ownership of factory, and destroys it when it is no longer needed.</em>
