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 fileName = QFileDialog::getOpenFileName(this, tr("Open Image"), "/home/jana", tr("Image Files (*.png *.jpg *.bmp)")); \endcode In the above example, a modal QFileDialog is created using a static function. The dialog initially displays the contents of the "/home/jana" directory, and displays files matching the patterns given in the string "Image Files (*.png *.jpg *.bmp)". The parent of the file dialog is set to \e this, and the window title is set to "Open Image". If you want to use multiple filters, separate each one with \e two semicolons. For example: \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 setFileMode(), you can specify what the user must select in the dialog: \code QFileDialog dialog(this); dialog.setFileMode(QFileDialog::AnyFile); \endcode In the above example, the mode of the file dialog is set to 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 "Save As" file dialog. Use ExistingFile if the user must select an existing file, or \l Directory if only a directory may be selected. See the \l QFileDialog::FileMode enum for the complete list of modes. The fileMode property contains the mode of operation for the dialog; this indicates what types of objects the user is expected to select. Use setFilter() to set the dialog's file filter. For example: \code dialog.setFilter(tr("Images (*.png *.xpm *.jpg)")); \endcode In the above example, the filter is set to \c{"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(). Use selectFilter() to select one of the filters you've given as the file dialog's default filter. The file dialog has two view modes: \l{QFileDialog::}{List} and \l{QFileDialog::}{Detail}. \l{QFileDialog::}{List} presents the contents of the current directory as a list of file and directory names. \l{QFileDialog::}{Detail} also displays a list of file and directory names, but provides additional information alongside each name, such as the file size and modification date. Set the mode with setViewMode(): \code dialog.setViewMode(QFileDialog::Detail); \endcode The last important function you will need to use when creating your own file dialog is selectedFiles(). \code QStringList fileNames; if (dialog.exec()) fileNames = dialog.selectedFiles(); \endcode In the above example, a modal file dialog is created and shown. If the user clicked OK, the file they selected is put in \c fileName. The dialog's working directory can be set with setDirectory(). Each file in the current directory can be selected using the selectFile() function. The \l{dialogs/standarddialogs}{Standard Dialogs} example shows how to use QFileDialog as well as other built-in Qt dialogs. \sa QDir, QFileInfo, QFile, QPrintDialog, QColorDialog, QFontDialog, {Standard Dialogs Example}, {Application Example} */ /*! \enum QFileDialog::AcceptMode \value AcceptOpen \value AcceptSave */ /*! \enum QFileDialog::ViewMode This enum describes the view mode of the file dialog; i.e. what information about each file will be displayed. \value Detail Displays an icon, a name, and details for each item in the directory. \value List Displays only an icon and a name for each item in the directory. \sa setViewMode() */ /*! \enum QFileDialog::FileMode 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.
