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}. */ /*! \enum QFileDialog::Mode This enum is used to indicate what the user may select in the file dialog, i.e. what the dialog will return if the user clicks OK. \value AnyFile The name of a file, whether it exists or not. \value ExistingFile The name of a single existing file. \value Directory The name of a directory.

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. */ /*!
