+    \class TQWidgetPlugin qwidgetplugin.h
+    \brief The TQWidgetPlugin class provides an abstract base for custom TQWidget plugins.
+
+    \ingroup plugins
+
+    The widget plugin is a simple plugin interface that makes it easy
+    to create custom widgets that can be included in forms using \link
+    designer-manual.book TQt Designer\endlink and used by applications.
+
+    Writing a widget plugin is achieved by subclassing this base
+    class, reimplementing the pure virtual functions keys(), create(),
+    group(), iconSet(), includeFile(), toolTip(), whatsThis() and
+    isContainer(), and exporting the class with the \c Q_EXPORT_PLUGIN
+    macro.
+
+    See the \link designer-manual.book TQt Designer manual's\endlink,
+    'Creating Custom Widgets' section in the 'Creating Custom Widgets'
+    chapter, for a complete example of a TQWidgetPlugin.
+
+    See also the \link plugins-howto.html Plugins
+    documentation\endlink and the \l{TQWidgetFactory} class that is
+    supplied with \link designer-manual.book TQt Designer\endlink.

+    \ingroup plugins
+
+    The widget container plugin is a subclass of TQWidgetPlugin and
+    extends the interface with functions necessary for supporting
+    complex container widgets via plugins. These container widgets are
+    widgets that have one or multiple sub widgets which act as the
+    widget's containers. If the widget has multiple container
+    subwidgets, they are referred to as "pages", and only one can be
+    active at a time. Examples of complex container widgets include:
+    TQTabWidget, TQWidgetStack and TQToolBox.
+
+    Writing a complex container widget plugin is achieved by
+    subclassing this base class. First by reimplementing
+    TQWidgetPlugin's pure virtual functions keys(), create(), group(),
+    iconSet(), includeFile(), toolTip(), whatsThis() and
+    isContainer(), and exporting the class with the \c Q_EXPORT_PLUGIN
+    macro. In addition containerOfWidget(), isPassiveInteractor() and
+    supportsPages() must be reimplemented. If the widget
+    supportsPages(), count(), currentIndex(), pageLabel(), page(),
+    pages() and createCode() must be implemented. If the widget
+    supportsPages() and you want to allow the containers pages to be
+    modified, you must also reimplement addPage(), insertPage(),
