+ \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". 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 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 may 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 will be shown 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 alongside each name, e.g. file size,
+ modification date, etc. Set the mode 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().
+
+ \section1 Creating and using preview widgets
+
+ 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
+ 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;
+
+ 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 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 QFilePreview widget see
+ \l{QFilePreview}.

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

+ QString s = QFileDialog::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 QString::null in which case
+ the current directory and a default caption will be used respectively.
+
+ Note on Windows that if \a dir is QString::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 QFileDialog, 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
+ QTimers 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
+ QStringList files = QFileDialog::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 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. (Note that on Windows the
+ dialog will spin a blocking modal event loop that will not dispatch any
+ QTimers 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
+ 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 the preview widget from both QWidget 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 QFileDialog::setPreviewMode(), QFileDialog::setContentsPreview(),
+ QFileDialog::setInfoPreview(), QFileDialog::setInfoPreviewEnabled(),
+ QFileDialog::setContentsPreviewEnabled().
+
+ For an example of a preview widget see qt/examples/qdir/qdir.cpp.
