Detailed Description

The QFileDialog class provides a dialog that allows users to select files or directories.

\inmodule QtWidgets

The QFileDialog class enables a user to traverse the file system to select one or many files or a directory.

The easiest way to create a QFileDialog is to use the static functions, such as \l getOpenFileName().

fileName = QFileDialog::getOpenFileName(this,

tr("Open Image"), "/home/jana", tr("Image Files (*.png *.jpg *.bmp)"));

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 this, and the window title is set to "Open Image".

If you want to use multiple filters, separate each one with two semicolons. For example:

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:

QFileDialog dialog(this);

dialog.setFileMode(QFileDialog::AnyFile);

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 can 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 setNameFilter() to set the dialog's file filter. For example:

In the above example, the filter is set to {"Images (*.png *.xpm *.jpg)"}. This means that only files with the extension png, xpm, or jpg are shown in the QFileDialog. You can apply several filters by using setNameFilters(). Use selectNameFilter() 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():

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

QStringList fileNames;
if (dialog.exec())
    fileNames = dialog.selectedFiles();

In the above example, a modal file dialog is created and shown. If the user clicked OK, the file they selected is put in 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.

By default, a platform-native file dialog is used if the platform has one. In that case, the widgets that would otherwise be used to construct the dialog are not instantiated, so related accessors such as layout() and itemDelegate() return null. Also, not all platforms show file dialogs with a title bar, so be aware that the caption text might not be visible to the user. You can set the \l DontUseNativeDialog option or set the \l{Qt::AA_DontUseNativeDialogs}{AA_DontUseNativeDialogs} application attribute to ensure that the widget-based implementation is used instead of the native dialog.

◆ FileMode

enum QFileDialog::FileMode

This enum is used to indicate what the user may select in the file dialog; that is, what the dialog returns 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. However, the native Windows file dialog does not support displaying files in the directory chooser. \value ExistingFiles The names of zero or more existing files.

◆ Option

enum QFileDialog::Option

Options that influence the behavior of the dialog.

\value ShowDirsOnly Only show directories. By default, both files and directories are shown.\br This option is only effective in the \l Directory file mode.

\value DontResolveSymlinks Don't resolve symlinks. By default, symlinks are resolved.

\value DontConfirmOverwrite Don't ask for confirmation if an existing file is selected. By default, confirmation is requested.\br This option is only effective if \l acceptMode is \l {QFileDialog::}{AcceptSave}). It is furthermore not used on macOS for native file dialogs.

\value DontUseNativeDialog Don't use a platform-native file dialog, but the widget-based one provided by Qt.\br By default, a native file dialog is shown unless you use a subclass of QFileDialog that contains the Q_OBJECT macro, the global \l{Qt::}{AA_DontUseNativeDialogs} application attribute is set, or the platform does not have a native dialog of the type that you require.\br For the option to be effective, you must set it before changing other properties of the dialog, or showing the dialog.

\value ReadOnly Indicates that the model is read-only.

\value HideNameFilterDetails Indicates if the file name filter details are hidden or not.

\value DontUseCustomDirectoryIcons Always use the default directory icon.\br Some platforms allow the user to set a different icon, but custom icon lookup might cause significant performance issues over network or removable drives.\br Setting this will enable the \l{QAbstractFileIconProvider::}{DontUseCustomDirectoryIcons} option in \l{iconProvider()}.\br This enum value was added in Qt 5.2.

◆ getExistingDirectory()

QString QFileDialog::getExistingDirectory	(	QWidget *	parent = nullptr,
		const QString &	caption = QString(),

static

This is a convenience static function that returns an existing directory selected by the user.

QString dir = QFileDialog::getExistingDirectory(this, tr("Open Directory"),
                                                "/home",

                                                | QFileDialog::DontResolveSymlinks);

This function creates a modal file dialog with the given parent widget. If parent is not \nullptr, the dialog is shown centered over the parent widget.

The dialog's working directory is set to dir, and the caption is set to caption. Either of these can be an empty string in which case the current directory and a default caption are used respectively.

The options argument holds various options about how to run the dialog. See the QFileDialog::Option enum for more information on the flags you can pass. To ensure a native file dialog, \l{QFileDialog::}{ShowDirsOnly} must be set.

On Windows and \macos, this static function uses the native file dialog and not a QFileDialog. However, the native Windows file dialog does not support displaying files in the directory chooser. You need to pass the \l{QFileDialog::}{DontUseNativeDialog} option, or set the global \l{Qt::}{AA_DontUseNativeDialogs} application attribute to display files using a QFileDialog.

Note that the \macos native file dialog does not show a title bar.

On 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 changes to {/var/tmp} after entering {/usr/tmp}. If options includes DontResolveSymlinks, the file dialog treats symlinks as regular directories.

On Windows, the dialog spins a blocking modal event loop that does not dispatch any QTimers, and if parent is not \nullptr then it positions the dialog just below the parent's title bar.

Warning: Do not delete parent during the execution of the dialog. If you want to do this, you must create the dialog yourself using one of the QFileDialog constructors.

static

This is a convenience static function that returns an existing directory selected by the user.

If the user presses Cancel, it returns an empty url.

The function is used similarly to QFileDialog::getExistingDirectory(). In particular parent, caption, dir and options are used in exactly the same way.

The main difference with QFileDialog::getExistingDirectory() comes from the ability offered to the user to select a remote directory. That's why the return type and the type of dir is QUrl.

The supportedSchemes argument allows to restrict the type of URLs the user is able to select. It is a way for the application to declare the protocols it supports to fetch the file content. An empty list means that no restriction is applied (the default). Support for local files ("file" scheme) is implicit and always enabled; it is not necessary to include it in the restriction.

When possible, this static function uses the native file dialog and not a QFileDialog. On platforms that don't support selecting remote files, Qt allows to select only local files.

static

This is a convenience static function that returns the content of a file selected by the user.

Use this function to access local files on Qt for WebAssembly, if the web sandbox restricts file access. Its implementation enables displaying a native file dialog in the browser, where the user selects a file based on the nameFilter parameter.

parent is ignored on Qt for WebAssembly. Pass parent on other platforms, to make the popup a child of another widget. If the platform doesn't support native file dialogs, the function falls back to QFileDialog.

The function is asynchronous and returns immediately. The fileOpenCompleted callback will be called when a file has been selected and its contents have been read into memory.

The function creates a modal file dialog with the given parent widget. If parent is not \nullptr, the dialog is shown centered over the parent widget.

The file dialog's working directory is set to dir. If dir includes a file name, the file is selected. Only files that match the given filter are shown. The selected filter is set to selectedFilter.

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Definition at line 244 of file qfiledialog.h.

◆ setDirectory() [2/2]

void QFileDialog::setDirectory ( const QString & directory )

Sets the file dialog's current directory.

Note: On iOS, if you set directory to \l{QStandardPaths::standardLocations()} {QStandardPaths::standardLocations(QStandardPaths::PicturesLocation).last()}, a native image picker dialog is used for accessing the user's photo album. The filename returned can be loaded using QFile and related APIs. For this to be enabled, the Info.plist assigned to QMAKE_INFO_PLIST in the project file must contain the key NSPhotoLibraryUsageDescription. See Info.plist documentation from Apple for more information regarding this key. This feature was added in Qt 5.5.

◆ setDirectoryUrl()

void QFileDialog::setDirectoryUrl ( const QUrl & directory )

Sets the file dialog's current directory url.

Note: The non-native QFileDialog supports only local files.; On Windows, it is possible to pass URLs representing one of the {virtual folders}, such as "Computer" or "Network". This is done by passing a QUrl using the scheme clsid followed by the CLSID value with the curly braces removed. For example the URL clsid:374DE290-123F-4565-9164-39C4925E467B denotes the download location. For a complete list of possible values, see the MSDN documentation on \l{https://docs.microsoft.com/en-us/windows/win32/shell/knownfolderid}{KNOWNFOLDERID}. This feature was added in Qt 5.5.

References d.

◆ setItemDelegate()

void QFileDialog::setItemDelegate ( QAbstractItemDelegate * delegate )

Sets the item delegate used to render items in the views in the file dialog to the given delegate.

Any existing delegate will be removed, but not deleted. QFileDialog does not take ownership of delegate.

Warning: You should not share the same instance of a delegate between views. Doing so can cause incorrect or unintuitive editing behavior since each view connected to a given delegate may receive the \l{QAbstractItemDelegate::}{closeEditor()} signal, and attempt to access, modify or close an editor that has already been closed.

Note that the model used is QFileSystemModel. It has custom item data roles, which is described by the \l{QFileSystemModel::}{Roles} enum. You can use a QFileIconProvider if you only want custom icons.

◆ setNameFilter()

void QFileDialog::setNameFilter ( const QString & filter )

Since: 4.4

Sets the filter used in the file dialog to the given filter.

If filter contains a pair of parentheses containing one or more filename-wildcard patterns, separated by spaces, then only the text contained in the parentheses is used as the filter. This means that these calls are all equivalent:

dialog.setNameFilter("All C++ files (*.cpp *.cc *.C *.cxx *.c++)");

dialog.setNameFilter("*.cpp *.cc *.C *.cxx *.c++");

Note: With Android's native file dialog, the mime type matching the given name filter is used because only mime types are supported.

◆ setNameFilters()

void QFileDialog::setNameFilters ( const QStringList & filters )

Since: 4.4

Sets the filters used in the file dialog.

Note that the filter {*.*} is not portable, because the historical assumption that the file extension determines the file type is not consistent on every operating system. It is possible to have a file with no dot in its name (for example, Makefile). In a native Windows file dialog, {*.*} matches such files, while in other types of file dialogs it might not match. So, it's better to use {*} if you mean to select any file.

const QStringList filters({"Image files (*.png *.xpm *.jpg)",
                           "Text files (*.txt)",
                           "Any files (*)"
                          });
QFileDialog dialog(this);
dialog.setNameFilters(filters);
dialog.exec();

\l setMimeTypeFilters() has the advantage of providing all possible name filters for each file type. For example, JPEG images have three possible extensions; if your application can open such files, selecting the image/jpeg mime type as a filter allows you to open all of them.

void QFileDialog::setOption	(	Option	option,

Since: 4.5 Sets the given option to be enabled if on is true; otherwise, clears the given option.

Options (particularly the \l DontUseNativeDialog option) should be set before changing dialog properties or showing the dialog.

Setting options while the dialog is visible is not guaranteed to have an immediate effect on the dialog (depending on the option and on the platform).

Property Documentation

◆ acceptMode

QFileDialog::acceptMode

readwrite

The accept mode of the dialog.

The action mode defines whether the dialog is for opening or saving files.

By default, this property is set to \l{AcceptOpen}.

See also: AcceptMode

Definition at line 32 of file qfiledialog.h.

Referenced by accept(), and labelText().

◆ defaultSuffix

QFileDialog::defaultSuffix

readwrite

Suffix added to the filename if no other suffix was specified.

This property specifies a string that is added to the filename if it has no suffix yet. The suffix is typically used to indicate the file type (e.g. "txt" indicates a text file).

If the first character is a dot ('.'), it is removed.

Definition at line 33 of file qfiledialog.h.

◆ fileMode

QFileDialog::fileMode

readwrite

The file mode of the dialog.

The file mode defines the number and type of items that the user is expected to select in the dialog.

By default, this property is set to AnyFile.

This function sets the labels for the FileName and \l{QFileDialog::}{Accept} \l{DialogLabel}s. It is possible to set custom text after the call to setFileMode().

See also: FileMode

Definition at line 31 of file qfiledialog.h.

Referenced by accept(), open(), and selectedFiles().

◆ options

QFileDialog::options

readwrite

The various options that affect the look and feel of the dialog.

Since: 4.5

By default, all options are disabled.

Options (particularly the \l DontUseNativeDialog option) should be set before changing dialog properties or showing the dialog.

Setting options while the dialog is visible is not guaranteed to have an immediate effect on the dialog (depending on the option and on the platform).

Setting options after changing other properties may cause these values to have no effect.

◆ supportedSchemes

QFileDialog::supportedSchemes

readwrite

The URL schemes that the file dialog should allow navigating to.

Since: 5.6

Setting this property allows to restrict the type of URLs the user can select. It is a way for the application to declare the protocols it supports to fetch the file content. An empty list means that no restriction is applied (the default). Support for local files ("file" scheme) is implicit and always enabled; it is not necessary to include it in the restriction.
