+    \title Qt Quick Controls 2 - Text Editor
+    \ingroup qtquickcontrols2-examples
+    \brief A QML app using Qt Quick Controls 2 and a C++ class to
+    provide a fully-functional rich-text editor application.
+
+    \image qtquickcontrols2-texteditor-desktop.png
+
+    The \e {Text Editor Example} presents a sample HTML file using the TextArea
+    control, preserving the HTML formatting. It uses a C++ class to handle the
+    document by providing options to open, format, and edit. The application
+    also lets you open and edit plain text files.
+
+    The C++ class, DocumentHandler, extends QObject and is registered
+    as a QML type under the namespace \c {io.qt.examples.texteditor 1.0}.
+
+    The following snippets show how the type is registered under
+    a namespace and later imported by \e main.qml.
+
+    QML type registration:
+
+    \code
+    #include <QtQml/qqml.h>
+    ...
+    qmlRegisterType<DocumentHandler>("io.qt.examples.texteditor", 1, 0, "DocumentHandler");
+    ...
+    \endcode
+
+    QML namespace import:
+
+    \code
+    import io.qt.examples.texteditor 1.0
+    \endcode
+
+    For more information about registering C++ classes as QML types, see
+    \l {Defining QML Types from C++}.
