+    \class QWebInspector
+    \since 4.6
+    \inmodule QtWebKit
+    \brief The QWebInspector class allows the placement and control of a
+    QWebPage's inspector.
+    The inspector can display a page's hierarchy, its loading statistics and
+    the current state of its individual elements. It is mostly used by web
+    developers.
+
+    The QWebPage to be inspected must be specified using the setPage() method.
+
+    A typical use of QWebInspector follows:
+
+    \snippet webkitsnippets/qtwebkit_qwebinspector_snippet.cpp 0
+
+    A QWebInspector can be made visible either programmatically using
+    setVisible(), or by the user through the attached QWebPage's context
+    menu.
+
+    \note A QWebInspector will display a blank widget if either:
+    \list
+        \o page() is null
+        \o QWebSettings::DeveloperExtrasEnabled is false
+    \endlist
+
+    \section1 Resources
+
+    This class acts mostly as a container and a controller for the inspector.
+    Most of the resources needed by the inspector are owned by the associated
+    QWebPage and are allocated the first time that:
+    \list
+        \o an element is inspected
+        \o the QWebInspector is shown.
+    \endlist
+
+    \section1 Inspector configuration persistence
+
+    The inspector allows the user to configure some options through its
+    user interface (e.g. the resource tracking "Always enable" option).
+    These settings will be persisted automatically by QtWebKit only if
+    your application previously called QCoreApplication::setOrganizationName()
+    and QCoreApplication::setApplicationName().
+    See QSettings's default constructor documentation for an explanation
+    of why this is necessary.
