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

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

  In the above example, a modal TQFileDialog 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". If you want to use multiple filters, separate each one with
  \e two semi-colons, e.g.
  \code
  "Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"
  \endcode

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

  \code
    TQFileDialog* fd = new TQFileDialog( this, "file dialog", TRUE );
    fd->setMode( TQFileDialog::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 may be selected.
  (See the \l TQFileDialog::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 will be shown in the TQFileDialog. 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, TQFileDialog::List which simply
  lists file and directory names and TQFileDialog::Detail which
  displays additional information alongside each name, e.g. file size,
  modification date, etc. Set the mode with setViewMode().

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

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

  \code
    TQString fileName;
    if ( fd->exec() == TQDialog::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 TQStringList.

  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().

  \section1 Creating and using preview widgets

  There are two kinds of preview widgets that can be used with
  TQFileDialogs: \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 TQFileDialog so
  that the user can see either the contents of the file, or information
  about the file.

  \code
    class Preview : public TQLabel, public TQFilePreview
    {
    public:
	Preview( TQWidget *parent=0 ) : TQLabel( parent ) {}

	void previewUrl( const TQUrl &u )
	{
	    TQString path = u.path();
	    TQPixmap 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
  TQLabel and TQFilePreview. File preview widgets \e must inherit from
  TQFilePreview.

  Inside the class we reimplement TQFilePreview::previewUrl(), this is
  where we determine what happens when a file is selected. In the
  above example we only show a preview of the file if it is a valid
  pixmap. Here's how to make a file dialog use a preview widget:

  \code
    Preview* p = new Preview;

    TQFileDialog* fd = new TQFileDialog( this );
    fd->setContentsPreviewEnabled( TRUE );
    fd->setContentsPreview( p, p );
    fd->setPreviewMode( TQFileDialog::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 preview of 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 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 TQFilePreview widget see
  \l{TQFilePreview}.

/*!
  This is a convenience static function that will return an existing directory
  selected by the user.

  \code
    TQString s = TQFileDialog::getExistingDirectory(
                    "/home",
		    this,
		    "get existing directory",
		    "Choose a directory",
		    TRUE );
  \endcode

  This function creates a modal file dialog called \a name, with
  parent, \a parent. If parent is not 0, 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 TQString::null in which case
  the current directory and a default caption will be used respectively.

  Note on Windows that if \a dir is TQString::null then the dialog's working
  directory will be set to the user's My Documents directory.

  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.

  Under Windows and Mac OS X, this static function will use the native
  file dialog and not a TQFileDialog, unless the style of the application
  is set to something other than the native style. (Note that on Windows the
  dialog will spin a blocking modal event loop that will not dispatch any
  TQTimers and if parent is not 0 then it will position the dialog just under
  the parent's titlebar).

  This is a convenience static function that will return one or more
  existing files selected by the user.

  \code
    TQStringList files = TQFileDialog::getOpenFileNames(
			    "Images (*.png *.xpm *.jpg)",
			    "/home",
			    this,
			    "open files dialog",
			    "Select one or more files to open" );
  \endcode

  This function creates a modal file dialog called \a name, with
  parent \a parent. If \a parent is not 0, 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 TQString::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 TQFileDialog, unless the style of the application
  is set to something other than the native style. (Note that on Windows the
  dialog will spin a blocking modal event loop that will not dispatch any
  TQTimers and if parent is not 0 then it will position the dialog just under
  the parent's titlebar).

  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 of files, you should
  iterate over a copy, e.g.
    \code
    TQStringList list = files;
    TQStringList::Iterator it = list.begin();
    while( it != list.end() ) {
	myProcessing( *it );
	++it;

  \brief The TQFilePreview class provides file previewing in TQFileDialog.

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

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

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

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