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

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.

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.

This is a convenience static function that returns 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 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.

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.

| 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, {.} 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.
\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.
