    \title Dir View Example
    \ingroup examples-itemviews
    \brief This example demonstrates the usage of a tree view.

    The Dir View example shows a tree view of the local file
    system. It uses the QFileSystemModel class to provide file
    and directory information.

    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

    \quotefromfile itemviews/dirview/main.cpp
    \skipto QCommandLineParser parser
    \printuntil parser.positionalArguments

    Declares a QFileSystemModel as data model for viewing
    the local file system. QFileSystem works with a cache, that is,
    it is updated continually with QFileSystemWatcher on that folder.

    \skipto QFileSystemModel
    \printuntil tree.setModel

    Creates a model/view implementation called \c tree
    for viewing the filesystem.

    \skipto tree.setAnimated(false)
    \printuntil tree.setWindowTitle

    Sets some formatting options for \c tree.
