/*!
  \class QFileDialog qfiledialog.h
  \brief The QFileDialog class provides dialogs that allow users to select files or directories.
  \ingroup dialogs
  \mainclass

  The QFileDialog class enables a user to traverse their 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, these static functions will call the native
  Windows file dialog and on Mac OS X, these static function will call
  the native Mac OS X file dialog.

  \code
    QString s = QFileDialog::getOpenFileName( "/home",
					      "Images (*.png *.xpm *.jpg)",
					      this,
					      "open file dialog"
					      "Choose a file" );
  \endcode

  In the above example, a modal QFileDialog is created using a static
  function.  The startup directory is set to "/home".  The file filter
  is set to "Images (*.png *.xpm *.jpg)".  The parent of the file dialog
  is set to \e this and it is given the identification name - "open file
  dialog".  The caption at the top of file dialog is set to "Choose a
  file".

  You can create your own QFileDialog without using the static
  functions.  By calling setMode(), you can set what can be returned by
  the QFileDialog.

  \code
    QFileDialog* fd = new QFileDialog( this, "file dialog", TRUE );
    fd->setMode( QFileDialog::AnyFile );
  \endcode

  In the above example, the mode of the file dialog is set to \c
  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 "File Save
  As" file dialog. Use \c ExistingFile if the user must select an
  existing file or \c Directory if only a directory must be selected.
  (See the \l QFileDialog::Mode enum for the complete list of modes.)

  You can retrieve the dialog's mode with mode(). Use setFilter() to set
  the dialog's file filter, e.g.

  \code
    fd->setFilter( "Images (*.png *.xpm *.jpg)" );
  \endcode

  In the above example, the filter is set to "Images (*.png *.xpm
  *.jpg)", this means that only files with the extension \c png, \c xpm
  or \c jpg files will be visible in the QFileDialog.  You can apply
  several filters by using setFilters() and add additional filters with
  addFilter(). Use setSelectedFilter() to select one of the filters
  you've given as the file dialog's default filter. Whenever the user
  changes the filter the filterSelected() signal is emitted.

    The file dialog has two  view modes, QFileDialog::List which simply
    lists file and directory names and QFileDialog::Detail which
    displays additional information beside each name, e.g. file size,
    modification date, etc. Set the move with setViewMode().

  \code
    fd->setViewMode( QFileDialog::Detail );
  \endcode

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

  \code
    QString fileName;
    if ( fd->exec() == QDialog::Accepted )
	fileName = fd->selectedFile();
  \endcode

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

  If you are using the \c ExistingFiles mode then you will need to use
  selectedFiles() which will return the selected files in a QStringList.

  The dialog's working directory can be set with setDir(). The display
  of hidden files is controlled with setShowHiddenFiles(). The dialog
  can be forced to re-read the directory with rereadDir() and re-sort
  the directory with resortDir(). All the files in the current directory
  can be selected with selectAll().

  <h3>Creating and using preview widgets</h3>

  There are two kinds of preview widgets that can be used with
  QFileDialogs: \e content preview widgets and \e information preview
  widgets. They are created and used in the same way except that the
  function names differ, e.g. setContentsPreview() and setInfoPreview().

  A preview widget is a widget that is placed inside a QFileDialog so
  that the user can see either the contents of the file, or information
  about the file.

  \code
    class Preview : public QLabel, public QFilePreview
    {
    public:
	Preview( QWidget *parent=0 ) : QLabel( parent ) {}

	void previewUrl( const QUrl &u )
	{
	    QString path = u.path();
	    QPixmap pix( path );
	    if ( pix.isNull() )
		setText( "This is not a pixmap" );
	    else
		setPixmap( pix );
	}
    };
  \endcode

  In the above snippet, we create a preview widget which inherits from
  QLabel and QFilePreview. File preview widgets \e must inherit from
  QFilePreview.

  Inside the class we reimplement QFilePreview::previewUrl(), this is
  where we determine what happens when a file is selected.  In the case
  above we only show a preview of the file if it is a valid pixmap.
  Now we tell a file dialog that we have a preview widget that we want
  it to use.

  \code
    Preview* p = new Preview;

    QFileDialog* fd = new QFileDialog( this );
    fd->setContentsPreviewEnabled( TRUE );
    fd->setContentsPreview( p, p );
    fd->setPreviewMode( QFileDialog::Contents );
    fd->show();
  \endcode

  The first line creates an instance of our preview widget.  We then
  create our file dialog and call setContentsPreviewEnabled( TRUE ),
  this tell the file dialog to preview the contents of the currently
  selected file.  We then call setContentsPreview() -- note that we pass
  the same preview widget twice. Finally, before showing the file
  dialog, we call setPreviewMode() setting the mode to \e Contents which
  will show the contents the file that the user has selected.

  If you create another preview widget that is used for displaying
  information about a file, create it in the same way as we have the
  contents preview widget and call setInfoPreviewEnabled(), and
  setInfoPreview().  Then the user will be able to switch between the
  two preview modes.

  For more information about creating a QFilePreview widget see QFilePreview.

  The function creates a modal file dialog with parent \a parent, and
  name \a name.  If a parent is specified, then the dialog will be shown
  centered over the parent.

  The file dialog's working directory will be set to \a startWith. If \a
  startWith includes a file name, the file will be selected. The filter
  is set to \a filter so that only those files which match the filter
  are shown.  The filter selected is set to \a selectedFilter. The parameters
  \a startWith, \a selectedFilter and \a filter may be QString::null.

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

  Under Windows and Mac OS X, this static function will use the native
  file dialog and not a QFileDialog, unless the style of the application
  is set to something other than the native style.

  Under Unix/X11, the normal behavior of the file dialog is to resolve
  and follow symlinks.  For example, if /usr/tmp is a symlink to /var/tmp,
  the file dialog will change to /var/tmp after entering /usr/tmp.
  If \a resolveSymlinks is FALSE, the file dialog will treat
  symlinks as regular directories.

  This is a convenience static function that will return an existing directory

		    this, "get existing directory"
		    "Choose a directory", TRUE );
  \endcode

  This function creates a modal file dialog with parent \a parent,
  and name \a name. If a parent is specified the dialog
  will be shown centered over the parent.

  The dialog's working directory is set to \a dir, and the caption is
  set to \a caption. Either of these may be QString::null in which case
  the current directory and a default caption will be used respectively.

  If \a dirOnly is TRUE, then only directories will be shown in
  the file dialog; otherwise both directories and files will be shown.

  Under Unix/X11, the normal behavior of the file dialog is to resolve
  and follow symlinks.  For example, if /usr/tmp is a symlink to /var/tmp,
  the file dialog will change to /var/tmp after entering /usr/tmp.
  If \a resolveSymlinks is FALSE, the file dialog will treat
  symlinks as regular directories.

/*! \class QFileIconProvider qfiledialog.h

  \brief The QFileIconProvider class provides icons for QFileDialog to
  use.

  \ingroup misc

  By default QFileIconProvider is not used, but any application or
  library can subclass it, reimplement pixmap() to return a suitable
  icon, and make all QFileDialog objects use it by calling the static
  function QFileDialog::setIconProvider().

  It is advisable to make all the icons that QFileIconProvider returns be
  the same size or at least the same width.  This makes the list view
  look much better.

  \endcode

  The function creates a modal file dialog with parent \a parent, and
  name \a name.  If a parent is specified, then the dialog will be shown
  centered over the parent.

  The file dialog's working directory will be set to \a dir. If \a
  dir includes a file name, the file will be selected. The filter
  is set to \a filter so that only those files which match the filter
  are shown.  The filter selected is set to \a selectedFilter. The parameters
  \a dir, \a selectedFilter and \a filter may be QString::null.

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

  Under Windows and Mac OS X, this static function will use the native
  file dialog and not a QFileDialog, unless the style of the application
  is set to something other than the native style.

  Under Unix/X11, the normal behavior of the file dialog is to resolve
  and follow symlinks.  For example, if /usr/tmp is a symlink to /var/tmp,
  the file dialog will change to /var/tmp after entering /usr/tmp.
  If \a resolveSymlinks is FALSE, the file dialog will treat
  symlinks as regular directories.

  Note that if you want to iterate over the list, you should
  iterate over a copy, e.g.
    \code
    QStringList list = files;
    QStringList::Iterator it = list.begin();
    while( it != list.end() ) {
	myProcessing( *it );
	++it;
    }

  \class QFilePreview qfiledialog.h
  \ingroup misc
  \brief The QFilePreview class provides file previewing in QFileDialog.

  This class is an abstract base class which is used to implement
  widgets that can display a preview of a file in a QFileDialog.

  You must derive your preview widget
  from both QWidget and from this class. Then you must reimplement
  the previewUrl() function of this class, which is called by the file dialog
  if the preview of a URL should be shown.

  See also QFileDialog::setPreviewMode(), QFileDialog::setContentsPreview(),
  QFileDialog::setInfoPreview(), QFileDialog::setInfoPreviewEnabled(),
  QFileDialog::setContentsPreviewEnabled().

  For an example of a preview widget see qt/examples/qdir/qdir.cpp.
*/

/*!
  Constructs the QFilePreview.
*/

QFilePreview::QFilePreview()
{
}

/*!
  \fn void QFilePreview::previewUrl( const QUrl &url )

  This function is called by QFileDialog if a preview
  for the \a url should be shown. Reimplement this
  function to perform file/URL previews.
