Detailed Description

The QFileDialog class provides a dialog which allows the selection of files or directories. It is generally easier to create a QFileDialog using the static methods. On Windows, OS X, KDE, and GNOME, these static methods will call the native file dialog when possible.

Example One

In the following example a modal dialog is created using a static method. The dialog will initially display the contents of the "/home/frank" directory and every file which matches the given filter. The parent of the file dialog will be this, the title is "Open Image", and the filter is "Image Files (*.png *.jpg *.bmp)".

fileName = QFileDialog::getOpenFileName(this, tr("Open Image"), "/home/frank", tr("Image Files (*.png *.jpg *.bmp)"));

To use multiple filters separate each one with two semicolons as shown below.

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

Example Two

This example shows how to create a QFileDialog without using the static methods. The call to setFileMode() is used to specify what type of file or directory the user may select.

The mode of QFileDialog::AnyFile means the user can select any file, or even specify a file that does not exist. This mode is useful for creating a "Save As" file dialog.

Using a mode of QFileDialog::ExistingFile the user must select an existing file.

The mode of QFileDialog::Directory only allows a directory to be selected.

Use the setNameFilter() method to set the filter of what files will be displayed.

There are two different view modes.

List mode presents the contents of the current directory as a list of file and directory names.

Detail mode displays a list of file and directory names and also provides additional information such as the file size and modification date.

QFileDialog dialog(this);
 
dialog.setFileMode(QFileDialog::AnyFile);
dialog.setNameFilter(tr("Images (*.png *.xpm *.jpg)"));
dialog.setViewMode(QFileDialog::Detail);

The last method you will need when creating your own file dialog is selectedFiles(). When the user selects a file and then clicks OK, the file name is assigned to the variable fileNames.

QStringList fileNames;
 
if (dialog.exec()) {
   fileNames = dialog.selectedFiles();
}

Member Enumeration Documentation

enum QFileDialog::AcceptMode

Constant	Value
`QFileDialog::AcceptOpen`	`0`
`QFileDialog::AcceptSave`	`1`

enum QFileDialog::DialogLabel

Constant	Value
`QFileDialog::LookIn`	`0`
`QFileDialog::FileName`	`1`
`QFileDialog::FileType`	`2`
`QFileDialog::Accept`	`3`
`QFileDialog::Reject`	`4`

enum QFileDialog::FileDialogOption

This enum indicates various settings for how the file dialog should be displayed.

Constant	Value	Description
QFileDialog::ShowDirsOnly	0x00000001	Only show directories in the file dialog. By default both files and directories are shown. (Valid only in the Directory file mode.)
QFileDialog::DontResolveSymlinks	0x00000002	Do not resolve symlinks in the file dialog. By default symlinks are resolved.
QFileDialog::DontConfirmOverwrite	0x00000004	Do not ask for confirmation if an existing file is selected. By default confirmation is requested.
QFileDialog::DontUseSheet	0x00000008	The static functions will always be an application modal dialog. If you want to use sheets, use QFileDialog::open() instead.
QFileDialog::DontUseNativeDialog	0x00000010	Do not use the native file dialog. By default, the native file dialog is used unless you use a subclass of QFileDialog that contains the CS_OBJECT macro, or the platform does not have a native dialog of the type that you require.
QFileDialog::ReadOnly	0x00000020	Indicates that the model is readonly.
QFileDialog::HideNameFilterDetails	0x00000040	Indicates if the file name filter details are hidden or not.

QString QFileDialog::getExistingDirectory	(	QWidget *	parent = `nullptr`,
		const QString &	caption = `QString()`,
		const QString &	dir = `QString()`,
		FileDialogOptions	options = `ShowDirsOnly`
	)

static

This is a convenience method which will return an existing directory selected by the user.

QString dir = QFileDialog::getExistingDirectory(this, tr("Open Directory"),

"/home", QFileDialog::ShowDirsOnly | QFileDialog::DontResolveSymlinks);

This method creates a modal file dialog with the given parent. If parent is not a nullptr, the dialog will be shown centered over the parent widget. The dialog's working directory is set to dir, and the title 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.

The options argument holds various options about how to run the dialog. Refer to the FileDialogOption enum for more information on the flags which can be passed. To ensure a native file dialog, ShowDirsOnly must be set.

On Windows and Mac OS X this static method will use a native file dialog and not one created by this class. On Windows the dialog will run a blocking modal event loop that will not dispatch any QTimers, and if parent is not a nullptr then it will position the dialog just below the parent's 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.

Warning: Do not delete parent during the execution of the dialog. If you want to do this, create the dialog using one of the QFileDialog constructors.

This is a convenience method which will return an existing directory selected by the user. If the user presses Cancel an empty url is returned.

The method is used similarly to QFileDialog::getExistingDirectory(). In particular parent, caption, dir and options are used in the exact same way. The main difference between this method and QFileDialog::getExistingDirectory(), is this method allows the user to select a remote directory.

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 in the restriction.

When possible this method will use a native file dialog and not one created by this class. On platforms which do not support selecting remote files this method will allow the user to select only local files.

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 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.
