+    \class QDockWindow qdockwindow.h
+    \brief The QDockWindow class provides a widget which can be docked
+    inside a QDockArea or floated as a top level window on the
+    desktop.
+
+    \ingroup application
+    \mainclass
+
+    This class handles moving, resizing, docking and undocking dock
+    windows. QToolBar is a subclass of QDockWindow so the
+    functionality provided for dock windows is available with the same
+    API for toolbars.
+
+    \img qmainwindow-qdockareas.png QDockWindows in a QDockArea
+    \caption Two QDockWindows (\l{QToolBar}s) in a \l QDockArea
+
+    \img qdockwindow.png A QDockWindow
+    \caption A Floating QDockWindow
+
+    If the user drags the dock window into the dock area the dock
+    window will be docked. If the user drags the dock area outside any
+    dock areas the dock window will be undocked (floated) and will
+    become a top level window. Double clicking a floating dock
+    window's titlebar will dock the dock window to the last dock area
+    it was docked in. Double clicking a docked dock window's handle
+    will undock (float) the dock window.
+    \omit
+    Single clicking a docked dock window's handle will minimize the
+    dock window (only its handle will appear, below the menu bar).
+    Single clicking the minimized handle will restore the dock window
+    to the last dock area that it was docked in.
+    \endomit
+    If the user clicks the close button (which does not appear on
+    dock windows by default - see \l closeMode) the dock window will
+    disappear. You can control whether or not a dock window has a
+    close button with setCloseMode().
+
+    QMainWindow provides four dock areas (top, left, right and bottom)
+    which can be used by dock windows. For many applications using the
+    dock areas provided by QMainWindow is sufficient. (See the \l
+    QDockArea documentation if you want to create your own dock
+    areas.) In QMainWindow a right-click popup menu (the dock window
+    menu) is available which lists dock windows and can be used to
+    show or hide them. (The popup menu only lists dock windows that
+    have a \link setCaption() caption\endlink.)
+
+    When you construct a dock window you \e must pass it a QDockArea
+    or a QMainWindow as its parent if you want it docked. Pass 0 for
+    the parent if you want it floated.
+
+    \code
+    QToolBar *fileTools = new QToolBar( this, "File Actions" );
+    moveDockWindow( fileTools, Left );
+    \endcode
+
+    In the example above we create a new QToolBar in the constructor
+    of a QMainWindow subclass (so that the \e this pointer points to
+    the QMainWindow). By default the toolbar will be added to the \c
+    Top dock area, but we've moved it to the \c Left dock area.
+
+    A dock window is often used to contain a single widget. In these
+    cases the widget can be set by calling setWidget(). If you're
+    constructing a dock window that contains multiple widgets, e.g. a
+    toolbar, arrange the widgets within a box layout inside the dock
+    window. To do this use the boxLayout() function to get a pointer
+    to the dock window's box layout, then add widgets to the layout
+    using the box layout's QBoxLayout::addWidget() function. The dock
+    window will dynamically set the orientation of the layout to be
+    vertical or horizontal as necessary, although you can control this
+    yourself with setOrientation().
+
+    Although a common use of dock windows is for toolbars, they can be
+    used with any widgets. (See the \link designer-manual.book Qt
+    Designer\endlink and \link linguist-manual.book Qt
+    Linguist\endlink applications, for example.) When using larger
+    widgets it may make sense for the dock window to be resizable by
+    calling setResizeEnabled(). Resizable dock windows are given
+    splitter-like handles to allow the user to resize them within
+    their dock area. When resizable dock windows are undocked they
+    become top level windows and can be resized like any other top
+    level windows, e.g. by dragging a corner or edge.
+
+    Dock windows can be docked and undocked using dock() and undock().
+    A dock window's orientation can be set with setOrientation(). You
+    can also use QDockArea::moveDockWindow(). If you're using a
+    QMainWindow, QMainWindow::moveDockWindow() and
+    QMainWindow::removeDockWindow() are available.
+
+    A dock window can have some preferred settings, for example, you
+    can set a preferred offset from the left edge (or top edge for
+    vertical dock areas) of the dock area using setOffset(). If you'd
+    prefer a dock window to start on a new \link qdockarea.html#lines
+    line\endlink when it is docked use setNewLine(). The
+    setFixedExtentWidth() and setFixedExtentHeight() functions can be
+    used to define the dock window's preferred size, and the
+    setHorizontallyStretchable() and setVerticallyStretchable()
+    functions set whether the dock window can be stretched or not.
+    Dock windows can be moved by default, but this can be changed with
+    setMovingEnabled(). When a dock window is moved it is shown as a
+    rectangular outline, but it can be shown normally using
+    setOpaqueMoving().
+
+    When a dock window's visibility changes, i.e. it is shown or
+    hidden, the visibilityChanged() signal is emitted. When a dock
+    window is docked, undocked or moved inside the dock area the
+    placeChanged() signal is emitted.
