Here is an example involving multiple selectors matching at the same time. The example is sorted so that the lowest matching file would be chosen if all selectors were present:. Create a QFileSelector instance. This instance will have the same static selectors as other QFileSelector instances, but its own set of extra selectors. If supplied, it will have the given QObject parent.
Sets the list of extra selectors which have been added programmatically to this instance. Documentation contributions included herein are the copyrights of their respective owners.

But of course, it only lets me select one folder. How can I change it to select multiple folders and return them in a list? As far as I know you can't do that with the native FileDialog.
There, however, exists a workaround in which you don't use the native dialog:. This workaround is a bit clunky however, but it's the best solution I know of other than rolling your own custom dialog.

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. This enum is used to indicate what the user may select in the file dialog; i. It stores an OR combination of Option values.
This enum describes the view mode of the file dialog; i. 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. The file mode defines the number and type of items that the user is expected to select in the dialog. It is possible to set custom text after the call to setFileMode. 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. See also setOption and testOption. 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.
By default, the Detail mode is used to display information about files and directories. Constructs a file dialog with the given parent and caption that initially displays the contents of the specified directory. The contents of the directory are filtered before being shown in the dialog, using a semicolon-separated list of filters specified by filter.
When the current file changes for local operations, this signal is emitted with the new file name as the path parameter. When the current file changes, this signal is emitted with the new file URL as the url parameter.
When the selection changes for local operations and the dialog is accepted, this signal is emitted with the possibly empty selected file. See also currentChanged and QDialog::Accepted. When the selection changes for local operations and the dialog is accepted, this signal is emitted with the possibly empty list of selected files. When the selection changes and the dialog is accepted, this signal is emitted with the possibly empty selected url.
When the selection changes and the dialog is accepted, this signal is emitted with the possibly empty list of selected urls. 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, ShowDirsOnly must be set. However, the native Windows file dialog does not support displaying files in the directory chooser. 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.
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. If the user presses Cancel, it returns an empty url. 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. 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. This is a convenience static function that returns an existing file selected by the user.
If the user presses Cancel, it returns a null string. The function creates a modal file dialog with the given parent widget. The file dialog's working directory will be set to dir. If dir includes a file name, the file will be selected. Only files that match the given filter are shown.
The filter selected is set to selectedFilter. The parameters dir , selectedFilter , and filter may be empty strings. If you want multiple filters, separate them with ';;', for example:.
