+  \class TQWidgetFactory
+
+  \brief The TQWidgetFactory class provides for the dynamic creation of widgets
+  from TQt Designer .ui files.
+
+  This class basically offers two things:
+
+  \list
+
+  \i Dynamically creating widgets from \link designer-manual.book TQt
+  Designer\endlink user interface description files.
+  You can do this using the static function TQWidgetFactory::create().
+  This function also performs signal and slot connections, tab
+  ordering, etc., as defined in the .ui file, and returns the
+  top-level widget in the .ui file. After creating the widget you can
+  use TQObject::child() and TQObject::queryList() to access child
+  widgets of this returned widget.
+
+  \i Adding additional widget factories to be able to create custom
+  widgets. See createWidget() for details.
+
+  \endlist
+
+  This class is not included in the TQt library itself. To use it you
+  must link against \c libtqui.so (Unix) or \c tqui.lib (Windows), which is
+  built into \c INSTALL/lib if you built \e{TQt Designer} (\c INSTALL is
+  the directory where TQt is installed ).
+
+  If you create a TQMainWindow using a TQWidgetFactory, be aware that
+  it already has a central widget. Therefore, you need to delete this
+  one before setting another one.
+
+  See the "Creating Dynamic Dialogs from .ui Files" section of the \link
+  designer-manual.book TQt Designer manual\endlink for an example. See
+  also the \l{TQWidgetPlugin} class and the \link plugins-howto.html
+  Plugins documentation\endlink.

+
+  This function also performs signal and slot connections, tab
+  ordering, etc., as described in the .ui file. In \e{TQt Designer} it
+  is possible to add custom slots to a form and connect to them. If
+  you want these connections to be made, you must create a class
+  derived from TQObject, which implements all these slots. Then pass an
+  instance of the object as \a connector to this function. If you do
+  this, the connections to the custom slots will be done using the \a

+
+    If \a className is a widget in the TQt library, it is directly
+    created by this function. If the widget isn't in the TQt library,
+    each of the installed widget plugins is asked, in turn, to create
+    the widget. As soon as a plugin says it can create the widget it
+    is asked to do so. It may occur that none of the plugins can
+    create the widget, in which case each installed widget factory is
+    asked to create the widget (see addWidgetFactory()). If the widget
+    cannot be created by any of these means, 0 is returned.
+
+    If you have a custom widget, and want it to be created using the
+    widget factory, there are two approaches you can use:
+
+    \list 1
+
+    \i Write a widget plugin. This allows you to use the widget in
+    \e{TQt Designer} and in this TQWidgetFactory. See the widget plugin
+    documentation for further details. (See the "Creating Custom
+    Widgets with Plugins" section of the \link designer-manual.book TQt
+    Designer manual\endlink for an example.
+
+    \i Subclass TQWidgetFactory. Then reimplement this function to
+    create and return an instance of your custom widget if \a
+    className equals the name of your widget, otherwise return 0. Then
+    at the beginning of your program where you want to use the widget
+    factory to create widgets do a:
+    \code
+    TQWidgetFactory::addWidgetFactory( new MyWidgetFactory );
+    \endcode
+    where MyWidgetFactory is your TQWidgetFactory subclass.
