-    \title Dir View Example
-    \ingroup examples-itemviews
-    \brief This example demonstrates the usage of a tree view, and smooth flicking on a touchscreen.
-
-    The Dir View example shows a tree view of the local file
-    system. It uses the QFileSystemModel class to provide file
-    and directory information.

-    \skipto QCommandLineParser parser
-    \printuntil parser.positionalArguments
-
-    The example supports a number of command line options.
-    These options include:
-    \list
-        \li Application description
-        \li -help option
-        \li -version option
-        \li if the optionc {-c} is specified, the application will not
-            use custom directory options
-    \endlist
-
-    \skipto QFileSystemModel
-    \printuntil tree.setModel
-
-    Declares \c model as data model for reading the local filesystem.
-    \c model.setRootPath("") sets the current folder as the folder from
-    which \c model will start reading.
-    QTreeView object \c tree visualizes the filesystem in a tree structure.
-
-    \skipto tree.setAnimated(false)
-    \printuntil tree.setColumnWidth
-
-    Sets layout options for animation, indentation, sorting, and sizing of the
-    filesystem tree.
-
-    \skipto QScroller::grabGesture
-    \printuntil QScroller::grabGesture
-
-    Creates a \l QScroller instance to recognize gestures on touchscreens,
-    so that you can flick the tree view with your finger.
