The QFileDialog class provides a dialog that allow users to select files or directories.
\inmodule QtWidgets
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.
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:
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 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
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: \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 will need to use when creating your own file dialog is 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 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. 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 to ensure that the widget-based implementation will be used instead of the native dialog.

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. 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.

enum QFileDialog::Option |
\value ShowDirsOnly Only show directories in the file dialog.
By default both files and directories are shown. (Valid only in the \l Directory file mode.)
\value DontResolveSymlinks Don't resolve symlinks in the file dialog. By default symlinks are resolved.
\value DontConfirmOverwrite Don't ask for confirmation if an existing file is selected. By default confirmation is requested.
Note: This option is not supported on macOS when using the native file dialog.
\value 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.
\value ReadOnly Indicates that the model is readonly.
\value HideNameFilterDetails Indicates if the file name filter details are hidden or not.
\value 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 QFileIconProvider::DontUseCustomDirectoryIcons option in the icon provider. This enum value was added in Qt 5.2.

This is a convenience static function that will return an existing directory selected by the user.
This function creates a modal file dialog with the given parent widget. If parent is not \nullptr, 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 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 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 \l{QFileDialog::}{DontUseNativeDialog} 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 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 \nullptr then it will position the dialog just below the parent's title bar.

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 QFileDialog::getExistingDirectory(). In particular parent, caption, dir and options are used in the exact 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 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 the content of a file selected by the user.
This function is used to access local files on Qt for WebAssembly, where the web sandbox places restrictions on how such access may happen. Its implementation will make the browser display a native file dialog, where the user makes the file selection based on the parameter nameFilter.
It can also be used on other platforms, where it will fall back to using 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.

void QFileDialog::setNameFilters | ( | const QStringList & | filters | ) |
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.
\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 will allow you to open all of them.

suffix added to the filename if no other suffix was specified
This property specifies a string that will be added to the filename if it has no suffix already. 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.

the various options that affect the look and feel of the dialog
By default, all options are disabled.
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.

the URL schemes that the file dialog should allow navigating to.
Setting this property 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.
