The easiest way to create a Q3FileDialog 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. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 0 In the above example, a modal Q3FileDialog 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 semicolons, e.g. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 1 You can create your own Q3FileDialog without using the static functions. By calling setMode(), you can set what can be returned by the Q3FileDialog. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 2 In the above example, the mode of the file dialog is set to \l 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 \l ExistingFile if the user must select an existing file or \l Directory if only a directory may be selected. (See the \l Q3FileDialog::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. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 3 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 Q3FileDialog. 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, Q3FileDialog::List which simply lists file and directory names and Q3FileDialog::Detail which displays additional information alongside each name, e.g. file size, modification date, etc. Set the mode with setViewMode(). \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 4 The last important function you will need to use when creating your own file dialog is selectedFile(). \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 5 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 \l 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 Q3FileDialogs: \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 Q3FileDialog so that the user can see either the contents of the file, or information about the file. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 6 In the above snippet, we create a preview widget which inherits from QLabel and Q3FilePreview. File preview widgets \e must inherit from Q3FilePreview. Inside the class we reimplement Q3FilePreview::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: \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 7 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 Q3FilePreview widget see \l{Q3FilePreview}. */ /*! \enum Q3FileDialog::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. Both files and directories are displayed. \value DirectoryOnly The name of a directory. The file dialog will only display directories. \value ExistingFiles The names of zero or more existing files. See setMode(). */ /*! \enum Q3FileDialog::ViewMode This enum describes the view mode of the file dialog, i.e. what information about each file will be displayed. \value List Display file and directory names with icons. \value Detail Display file and directory names with icons plus additional information, such as file size and modification date.

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 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 an empty string. 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 Q3FileDialog, 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 title bar).

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. \snippet doc/src/snippets/code/src_qt3support_dialogs_q3filedialog.cpp 17 \sa getOpenFileName(), getSaveFileName(), getExistingDirectory() */ QStringList Q3FileDialog::getOpenFileNames(const QString & filter, const QString& dir, QWidget *parent, const char* name, const QString& caption, QString *selectedFilter, bool resolveSymlinks) { bool save_qt_resolve_symlinks = qt_resolve_symlinks; qt_resolve_symlinks = resolveSymlinks; QStringList filters; if (!filter.isEmpty()) filters = makeFiltersList(filter); makeVariables(); if (workingDirectory->isNull()) *workingDirectory = toRootIfNotExists( QDir::currentDirPath() ); if (!dir.isEmpty()) { // #### works only correct for local files Q3UrlOperator u(Q3FileDialogPrivate::encodeFileName(dir)); if (u.isLocalFile() && QFileInfo(u.path()).isDir()) { *workingDirectory = dir; } else { *workingDirectory = u.toString(); } } #if defined(Q_WS_WIN) if (qt_use_native_dialogs && qobject_cast(qApp->style())) return winGetOpenFileNames(filter, workingDirectory, parent, name, caption, selectedFilter); #elif defined(Q_WS_MAC) if (qt_use_native_dialogs && qobject_cast(qApp->style())) { QStringList sl = macGetOpenFileNames(filter, dir.isEmpty() ? 0 : workingDirectory, parent, name, caption, selectedFilter); for (int i = 0; i < sl.count(); ++i) sl.replace(i, sl.at(i).normalized(QString::NormalizationForm_C)); return sl; } #endif Q3FileDialog *dlg = new Q3FileDialog(*workingDirectory, QString(), parent, name ? name : "qt_filedlg_gofns", true); if (!caption.isNull()) dlg->setWindowTitle(caption); else dlg->setWindowTitle(Q3FileDialog::tr("Open")); dlg->setFilters(filters); if (selectedFilter) dlg->setFilter(*selectedFilter); dlg->setMode(Q3FileDialog::ExistingFiles); QString result; QStringList lst; if (dlg->exec() == QDialog::Accepted) { lst = dlg->selectedFiles(); *workingDirectory = dlg->d->url; if (selectedFilter) *selectedFilter = dlg->selectedFilter(); } delete dlg; qt_resolve_symlinks = save_qt_resolve_symlinks; return lst; } /*!
