Detailed Description

The QFileDialog class enables a user to traverse the 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.

fileName = QFileDialog.getOpenFileName(self,
    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:

"Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"

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:

dialog = QFileDialog(self)
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 Directory if only a directory may be selected. See the 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:

dialog.setNameFilter(tr("Images (*.png *.xpm *.jpg)"))

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 will be 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: List and Detail . List presents the contents of the current directory as a list of file and directory names. 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() :

dialog.setViewMode(QFileDialog.Detail)

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

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 Standard Dialogs example shows how to use QFileDialog as well as other built-in Qt dialogs.

By default, a platform-native file dialog will be used if the platform has one. In that case, the widgets which would otherwise be used to construct the dialog will not be instantiated, so related accessors such as layout() and itemDelegate() will return null. You can set the DontUseNativeDialog option to ensure that the widget-based implementation will be used instead of the native dialog.

PySide2.QtWidgets.QFileDialog.ViewMode

This enum describes the view mode of the file dialog; i.e. what information about each file will be displayed.

Constant

Description

QFileDialog.Detail

Displays an icon, a name, and details for each item in the directory.

QFileDialog.List

Displays only an icon and a name for each item in the directory.

See also

setViewMode()

PySide2.QtWidgets.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.

Constant

Description

QFileDialog.AnyFile

The name of a file, whether it exists or not.

QFileDialog.ExistingFile

The name of a single existing file.

QFileDialog.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.

QFileDialog.ExistingFiles

The names of zero or more existing files.

This value is obsolete since Qt 4.5:

Constant

Description

QFileDialog.DirectoryOnly

Use Directory and setOption ( ShowDirsOnly , true) instead.

QFileDialog.ShowDirsOnly

Only show directories in the file dialog. By default both files and directories are shown. (Valid only in the Directory file mode.)

QFileDialog.DontResolveSymlinks

Don’t resolve symlinks in the file dialog. By default symlinks are resolved.

QFileDialog.DontConfirmOverwrite

Don’t ask for confirmation if an existing file is selected. By default confirmation is requested.

QFileDialog.DontUseNativeDialog

Don’t use the native file dialog. By default, the native file dialog is used unless you use a subclass of QFileDialog that contains the Q_OBJECT macro, or the platform does not have a native dialog of the type that you require.

Note

This option must be set before changing dialog properties or showing the dialog.

Constant

Description

QFileDialog.ReadOnly

Indicates that the model is readonly.

QFileDialog.HideNameFilterDetails

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

QFileDialog.DontUseSheet

In previous versions of Qt, the static functions would create a sheet by default if the static function was given a parent. This is no longer supported and does nothing in Qt 4.5, The static functions will always be an application modal dialog. If you want to use sheets, use open() instead.

QFileDialog.DontUseCustomDirectoryIcons

Always use the default directory icon. Some platforms allow the user to set a different icon. Custom icon lookup cause a big performance impact over network or removable drives. Setting this will enable the DontUseCustomDirectoryIcons option in the icon provider. This enum value was added in Qt 5.2.

Parameters
  • parentQWidget

  • caption – unicode

  • dir – unicode

  • optionsOptions

Return type

unicode

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

dir = QFileDialog.getExistingDirectory(self, tr("Open Directory"),
                                       "/home",
                                       QFileDialog.ShowDirsOnly
                                       | QFileDialog.DontResolveSymlinks)

This function creates a modal file dialog with the given parent widget. If parent is not None , the dialog will be 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 may be an empty string in which case the current directory and a default caption will be used respectively.

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

On Windows and macOS , this static function will use 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 DontUseNativeDialog to display files using a QFileDialog .

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 will change to /var/tmp after entering /usr/tmp . If options includes DontResolveSymlinks , the file dialog will treat symlinks as regular directories.

On Windows, the dialog will spin a blocking modal event loop that will not dispatch any QTimers, and if parent is not None then it will position 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 should create the dialog yourself using one of the QFileDialog constructors.

static PySide2.QtWidgets.QFileDialog.getExistingDirectoryUrl([parent=None[, caption=""[, dir=QUrl()[, options=QFileDialog.ShowDirsOnly[, supportedSchemes=list()]]]]])
Parameters
  • parentQWidget

  • caption – unicode

  • dirQUrl

  • optionsOptions

  • supportedSchemes – list of strings

Return type

QUrl

This is a convenience static function that will return an existing directory selected by the user. If the user presses Cancel, it returns an empty url.

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

The main difference with 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 will be able to select. It is a way for the application to declare the protocols it will support to fetch the file content. An empty list means that no restriction is applied (the default). Supported 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 will use the native file dialog and not a QFileDialog . On platforms which don’t support selecting remote files, Qt will allow to select only local files.

This is a convenience static function that will return one or more existing files selected by the user. If the user presses Cancel, it returns an empty list.

The function is used similarly to getOpenFileNames() . In particular parent , caption , dir , filter , selectedFilter and options are used in the exact same way.

The main difference with getOpenFileNames() comes from the ability offered to the user to select remote files. That’s why the return type and the type of dir are respectively QList < QUrl > and QUrl .

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

  • optionsOptions

Return type

(fileName, selectedFilter)

This is a convenience static function that will return a file name selected by the user. The file does not have to exist.

It creates a modal file dialog with the given parent widget. If parent is not None , the dialog will be shown centered over the parent widget.

fileName = QFileDialog.getSaveFileName(self, tr("Save F:xile"),
                                       "/home/jana/untitled.png",

The filter selected is set to selectedFilter . The parameters dir , selectedFilter , and filter may be empty strings. Multiple filters are separated with ‘;;’. For instance:

"Images (*.png *.xpm *.jpg);;Text files (*.txt);;XML files (*.xml)"

The options argument holds various options about how to run the dialog, see the Option enum for more information on the flags you can pass.

The default filter can be chosen by setting selectedFilter to the desired value.

The dialog’s caption is set to caption . If caption is not specified, a default caption will be used.

On Windows, and macOS , this static function will use the native file dialog and not a QFileDialog .

On Windows the dialog will spin a blocking modal event loop that will not dispatch any QTimers, and if parent is not None then it will position the dialog just below the parent’s title bar. On macOS , with its native file dialog, the filter argument is ignored.

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 will change to /var/tmp after entering /usr/tmp . If options includes DontResolveSymlinks the file dialog will treat symlinks as regular directories.

PySide2.QtWidgets.QFileDialog.setMimeTypeFilters(filters)
Parameters

filters – list of strings

Sets the filters used in the file dialog, from a list of MIME types.

Convenience method for setNameFilters() . Uses QMimeType to create a name filter from the glob patterns and description defined in each MIME type.

Use application/octet-stream for the “All files (*)” filter, since that is the base MIME type for all files.

Calling overrides any previously set name filters, and changes the return value of nameFilters() .

QStringList mimeTypeFilters;
mimeTypeFilters << "image/jpeg" // will show "JPEG image (*.jpeg *.jpg *.jpe)
            << "image/png"  // will show "PNG image (*.png)"
            << "application/octet-stream"; // will show "All files (*)"

QFileDialog dialog(this);
dialog.setMimeTypeFilters(mimeTypeFilters);
dialog.exec();
PySide2.QtWidgets.QFileDialog.setNameFilter(filter)
Parameters

filter – unicode

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++")
PySide2.QtWidgets.QFileDialog.setNameFilterDetailsVisible(enabled)
Parameters

enabledbool

PySide2.QtWidgets.QFileDialog.setNameFilters(filters)
Parameters

filters – list of strings

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, *.* will match such files, while in other types of file dialogs it may not. So it is better to use * if you mean to select any file.

filters = QStringList()
filters << "Image files (*.png *.xpm *.jpg)"
        << "Text files (*.txt)"
        << "Any files (*)"

dialog = QFileDialog(this)
dialog.setNameFilters(filters)
dialog.exec_()

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 will allow you to open all of them.

PySide2.QtWidgets.QFileDialog.setOption(option[, on=true])
Parameters
  • optionOption

  • onbool

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

Options (particularly the DontUseNativeDialogs 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.

Parameters

PySide2.QtWidgets.QFileDialog.setProxyModel(model)
Parameters

modelQAbstractProxyModel

Sets the model for the views to the given proxyModel . This is useful if you want to modify the underlying model; for example, to add columns, filter data or add drives.

Any existing proxy model will be removed, but not deleted. The file dialog will take ownership of the proxyModel .

PySide2.QtWidgets.QFileDialog.setSidebarUrls(urls)
Parameters

urls

Sets the urls that are located in the sidebar.

For instance:

QList<QUrl> urls;
urls << QUrl::fromLocalFile("/Users/foo/Code/qt5")
     << QUrl::fromLocalFile(QStandardPaths::standardLocations(QStandardPaths::MusicLocation).first());

QFileDialog dialog;
dialog.setSidebarUrls(urls);
dialog.setFileMode(QFileDialog::AnyFile);
if(dialog.exec()) {
    // ...
}

The file dialog will then look like this:

../../_images/filedialogurls.png
