Detailed Description#

Warning

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 getOpenFileName() .

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 can 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 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: 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 need to use when creating your own file dialog is selectedFiles() .

fileNames = QStringList()
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 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 DontUseNativeDialog option or set the AA_DontUseNativeDialogs application attribute to ensure that the widget-based implementation is used instead of the native dialog.

class 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.

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.

See also

setFileMode()

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.

class AcceptMode#

Constant	Description
QFileDialog.AcceptOpen
QFileDialog.AcceptSave

class DialogLabel#

Constant	Description
QFileDialog.LookIn
QFileDialog.FileName

QFileDialog.Accept
QFileDialog.Reject

class Option#

(inherits enum.Flag) Options that influence the behavior of the dialog.

Constant

Description

QFileDialog.ShowDirsOnly

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

QFileDialog.DontResolveSymlinks

Don’t resolve symlinks. By default, symlinks are resolved.

QFileDialog.DontConfirmOverwrite

Don’t ask for confirmation if an existing file is selected. By default, confirmation is requested. This option is only effective if acceptMode is AcceptSave ). It is furthermore not used on macOS for native file dialogs.

QFileDialog.DontUseNativeDialog

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

QFileDialog.ReadOnly

Indicates that the model is read-only.

QFileDialog.HideNameFilterDetails

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

QFileDialog.DontUseCustomDirectoryIcons

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

options testOption

Constant	Description
QFileDialog.ShowDirsOnly	Only show directories. By default, both files and directories are shown. This option is only effective in the `Directory` file mode.
QFileDialog.DontResolveSymlinks	Don’t resolve symlinks. By default, symlinks are resolved.
QFileDialog.DontConfirmOverwrite	Don’t ask for confirmation if an existing file is selected. By default, confirmation is requested. This option is only effective if `acceptMode` is `AcceptSave` ). It is furthermore not used on macOS for native file dialogs.
QFileDialog.DontUseNativeDialog	Don’t use a platform-native file dialog, but the widget-based one provided by Qt. By default, a native file dialog is shown unless you use a subclass of `QFileDialog` that contains the Q_OBJECT macro, the global AA_DontUseNativeDialogs application attribute is set, or the platform does not have a native dialog of the type that you require. For the option to be effective, you must set it before changing other properties of the dialog, or showing the dialog.
QFileDialog.ReadOnly	Indicates that the model is read-only.
QFileDialog.HideNameFilterDetails	Indicates if the file name filter details are hidden or not.
QFileDialog.DontUseCustomDirectoryIcons	Always use the default directory icon. Some platforms allow the user to set a different icon, but custom icon lookup might cause significant performance issues over network or removable drives. Setting this will enable the DontUseCustomDirectoryIcons option in `iconProvider()` . This enum value was added in Qt 5.2.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property acceptModeᅟ: QFileDialog.AcceptMode#

This property holds 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 AcceptOpen .

See also

AcceptMode

Access functions:

acceptMode()
setAcceptMode()

property defaultSuffixᅟ: str#

This property holds 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.

Access functions:

defaultSuffix()
setDefaultSuffix()

property fileModeᅟ: QFileDialog.FileMode#

This property holds 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 Accept DialogLabel s. It is possible to set custom text after the call to setFileMode().

See also

FileMode

Access functions:

fileMode()
setFileMode()

property optionsᅟ: Combination of QAbstractFileIconProvider.Option#

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

By default, all options are disabled.

Options (particularly the 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.

See also

setOption() testOption()

Access functions:

options()
setOptions()

property supportedSchemesᅟ: list of strings#

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

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.

Access functions:

This is a convenience static function that returns 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 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 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 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 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 None 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 getExistingDirectoryUrl([parent=None[, caption=""[, dir=QUrl()[, options=QFileDialog.Option.ShowDirsOnly[, supportedSchemes=list()]]]]])#

Parameters:

parent – QWidget
caption – str
dir – QUrl
options – Combination of Option
supportedSchemes – list of strings

Return type:

QUrl

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 getExistingDirectory() . In particular parent, caption, dir and options are used in exactly the 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 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.

Typically this is used in conjunction with QSettings to restore the size from a past session.

Returns false if there are errors

static saveFileContent(fileContent, fileNameHint[, parent=None])#

Parameters:

fileContent – QByteArray
fileNameHint – str
parent – QWidget

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

This is a convenience static function that saves fileContent to a file, using a file name and location chosen by the user. fileNameHint can be provided to suggest a file name to the user.

Use this function to save content to 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 specifies an output file based on the fileNameHint argument.

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.

QByteArray imageData # obtained from e.g. QImage.save()
QFileDialog.saveFileContent(imageData, "myimage.png") # with filename hint
# OR
QFileDialog.saveFileContent(imageData) # no filename hint

saveState()#

Return type:: QByteArray

Saves the state of the dialog’s layout, history and current directory.

Typically this is used in conjunction with QSettings to remember the size for a future session. A version number is stored as part of the data.

selectFile(filename)#

Parameters:: filename – str

Selects the given filename in the file dialog.

selectedFiles()

selectMimeTypeFilter(filter)#

Parameters:: filter – str

Sets the current MIME type filter.

selectNameFilter(filter)#

Parameters:: filter – str

Sets the current file type filter. Multiple filters can be passed in filter by separating them with semicolons or spaces.

setNameFilter() setNameFilters() selectedNameFilter()

selectUrl(url)#

Parameters:: url – QUrl

Selects the given url in the file dialog.

Note

The non-native QFileDialog supports only local files.

selectedUrls()

selectedFiles()#

Return type:: list of strings

Returns a list of strings containing the absolute paths of the selected files in the dialog. If no files are selected, or the mode is not ExistingFiles or ExistingFile , selectedFiles() contains the current path in the viewport.

See also

selectedNameFilter() selectFile()

selectedMimeTypeFilter()#

Return type:: str

Returns The mimetype of the file that the user selected in the file dialog.

selectedNameFilter()#

Return type:: str

Returns the filter that the user selected in the file dialog.

See also

selectedFiles()

selectedUrls()#

Return type:: .list of QUrl

Returns a list of urls containing the selected files in the dialog. If no files are selected, or the mode is not ExistingFiles or ExistingFile , selectedUrls() contains the current path in the viewport.

selectedNameFilter() selectUrl()

setAcceptMode(mode)#

Parameters:: mode – AcceptMode

See also

acceptMode()

Setter of property acceptModeᅟ .

setDefaultSuffix(suffix)#

Parameters:: suffix – str

See also

defaultSuffix()

Setter of property defaultSuffixᅟ .

setDirectory(directory)#

Parameters:: directory – QDir

This is an overloaded function.

setDirectory(directory)

Parameters:: directory – str

Sets the file dialog’s current directory.

Note

On iOS, if you set directory to 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.

directory()

setDirectoryUrl(directory)#

Parameters:: directory – QUrl

Sets the file dialog’s current directory url.

Note

The non-native QFileDialog supports only local files.

Note

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 KNOWNFOLDERID . This feature was added in Qt 5.5.

setFileMode(mode)#

Parameters:: mode – FileMode

See also

fileMode()

Setter of property fileModeᅟ .

setFilter(filters)#

Parameters:: filters – Combination of Filter

Sets the filter used by the model to filters. The filter is used to specify the kind of files that should be shown.

See also

filter()

setHistory(paths)#

Parameters:: paths – list of strings

Sets the browsing history of the filedialog to contain the given paths.

See also

history()

setIconProvider(provider)#

Parameters:: provider – QAbstractFileIconProvider

Sets the icon provider used by the filedialog to the specified provider.

See also

iconProvider()

setItemDelegate(delegate)#

Parameters:: delegate – QAbstractItemDelegate

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 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 Roles enum. You can use a QFileIconProvider if you only want custom icons.

itemDelegate() setIconProvider() QFileSystemModel

setLabelText(label, text)#

Parameters:

label – DialogLabel
text – str

Sets the text shown in the filedialog in the specified label.

See also

labelText()

setMimeTypeFilters(filters)#

Parameters:: filters – list of strings

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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

def mimeTypeFilters({"image/jpeg",*.jpe):
                             "image/png", // will show "PNG image (*.png)"
                             "application/octet-stream" // will show "All files (*)"
                            })
dialog = QFileDialog(self)
dialog.setMimeTypeFilters(mimeTypeFilters)
dialog.exec()

See also

mimeTypeFilters()

setNameFilter(filter)#

Parameters:: filter – str

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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(filters)#

Parameters:: filters – list of strings

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

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.

QStringList filters({"Image files (*.png *.xpm *.jpg)",
                           "Text files (*.txt)",
                           "Any files (*)"
                          })
dialog = QFileDialog(self)
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 allows you to open all of them.

nameFilters()

setOption(option[, on=true])#

Parameters:

option – Option
on – bool

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

Options (particularly the 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.

options testOption()

setOptions(options)#

Parameters:: options – Combination of Option

See also

options()

setProxyModel(model)#

Parameters:: model – QAbstractProxyModel

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 is removed, but not deleted. The file dialog takes ownership of the proxyModel.

See also

proxyModel()

setSidebarUrls(urls)#

Parameters:: urls – .list of QUrl

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

Sets the urls that are located in the sidebar.

For instance:

urls = QList()
    urls << QUrl.fromLocalFile("/Users/foo/Code/qt5")
         << QUrl.fromLocalFile(QStandardPaths.standardLocations(QStandardPaths.MusicLocation).first())
    dialog = QFileDialog()
    dialog.setSidebarUrls(urls)
    dialog.setFileMode(QFileDialog.AnyFile)
    if dialog.exec():
        # ...

Then the file dialog looks like this:
