  \class QFileDialog
  \brief The QFileDialog class provides a dialog that allow users to select files or directories.
  \ingroup standard-dialogs


  The QFileDialog class enables a user to traverse the file system in
  order to select one or many files or a directory.

  The easiest way to create a QFileDialog is to use the static
  functions. On Windows, Mac OS X, KDE and GNOME, these static functions will
  call the native file dialog when possible.

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 0

  In the above example, a modal QFileDialog is created using a static
  function. The dialog initially displays the contents of the "/home/jana"
  directory, and displays files matching the patterns given in the
  string "Image Files (*.png *.jpg *.bmp)". The parent of the file dialog
  is set to \e this, and the window title is set to "Open Image".

  If you want to use multiple filters, separate each one with
  \e two semicolons. For example:

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 1

  You can create your own QFileDialog without using the static
  functions. By calling setFileMode(), you can specify what the user must
  select in the dialog:

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 2

  In the above example, the mode of the file dialog is set to
  AnyFile, meaning that the user can select any file, or even specify a
  file that doesn't exist. This mode is useful for creating a
  "Save As" file dialog. Use ExistingFile if the user must select an
  existing file, or \l Directory if only a directory may be selected.
  See the \l QFileDialog::FileMode enum for the complete list of modes.

  The fileMode property contains the mode of operation for the dialog;
  this indicates what types of objects the user is expected to select.
  Use setNameFilter() to set the dialog's file filter. For example:

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 3

  In the above example, the filter is set to \c{"Images (*.png *.xpm *.jpg)"},
  this means that only files with the extension \c png, \c xpm,
  or \c jpg will be shown in the QFileDialog. You can apply
  several filters by using setNameFilters(). Use selectNameFilter() to select
  one of the filters you've given as the file dialog's default filter.

  The file dialog has two view modes: \l{QFileDialog::}{List} and
  \l{QFileDialog::}{Detail}.
  \l{QFileDialog::}{List} presents the contents of the current directory
  as a list of file and directory names. \l{QFileDialog::}{Detail} also
  displays a list of file and directory names, but provides additional
  information alongside each name, such as the file size and modification
  date. Set the mode with setViewMode():

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 4

  The last important function you will need to use when creating your
  own file dialog is selectedFiles().

  \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 5

  In the above example, a modal file dialog is created and shown. If
  the user clicked OK, the file they selected is put in \c fileName.

  The dialog's working directory can be set with setDirectory().
  Each file in the current directory can be selected using
  the selectFile() function.

  The \l{dialogs/standarddialogs}{Standard Dialogs} example shows
  how to use QFileDialog as well as other built-in Qt dialogs.

    \value DontResolveSymlinks Don't resolve symlinks in the file
    dialog. By default symlinks are resolved.

    \value DontConfirmOverwrite Don't ask for confirmation if an
    existing file is selected.  By default confirmation is requested.

    \value DontUseNativeDialog Don't use the native file dialog. By
    default, the native file dialog is used unless you use a subclass
    of QFileDialog that contains the Q_OBJECT macro.

    \value ReadOnly Indicates that the model is readonly.

    \value HideNameFilterDetails Indicates if the file name filter details are
    hidden or not.

    \value DontUseSheet In previous versions of Qt, the static
    functions would create a sheet by default if the static function
    was given a parent. This is no longer supported and does nothing in Qt 4.5, The
    static functions will always be an application modal dialog. If
    you want to use sheets, use QFileDialog::open() instead.

    This is a convenience static function that returns an existing file
    selected by the user. If the user presses Cancel, it returns a null string.

    \snippet doc/src/snippets/code/src_gui_dialogs_qfiledialog.cpp 8

    The function creates a modal file dialog with the given \a parent widget.
    If \a parent is not 0, the dialog will be shown centered over the parent
    widget.

    The file dialog's working directory will be set to \a dir. If \a dir
    includes a file name, the file will be selected. Only files that match the
    given \a filter are shown. The filter selected is set to \a selectedFilter.
    The parameters \a dir, \a selectedFilter, and \a filter may be empty
    strings. If you want multiple filters, separate them with ';;', for
    example:

    \code
    "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"
    \endcode

    The \a options argument holds various options about how to run the dialog,
    see the QFileDialog::Option enum for more information on the flags you can
    pass.

    The dialog's caption is set to \a caption. If \a caption is not specified
    then a default caption will be used.

    On Windows and Mac OS X, this static function will use the native file
    dialog and not a QFileDialog.

    On Windows the dialog will spin a blocking modal event loop that will not
    dispatch any QTimers, and if \a parent is not 0 then it will position the
    dialog just below the parent's title bar.

    On Unix/X11, the normal behavior of the file dialog is to resolve and
    follow symlinks. For example, if \c{/usr/tmp} is a symlink to \c{/var/tmp},
    the file dialog will change to \c{/var/tmp} after entering \c{/usr/tmp}. If
    \a options includes DontResolveSymlinks, the file dialog will treat
    symlinks as regular directories.

    \warning Do not delete \a parent during the execution of the dialog. If you
    want to do this, you should create the dialog yourself using one of the
    QFileDialog constructors.
