The QFileDialog class provides a dialog that allow users to select files or directories.
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. On Windows, Mac OS X, KDE and GNOME, these static functions will call the native file dialog when possible.
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 Directory if only a directory may be selected. See the 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: QFileDialog::List and QFileDialog::Detail. QFileDialog::List presents the contents of the current directory as a list of file and directory names. 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 Standard Dialogs example shows how to use QFileDialog as well as other built-in Qt dialogs.

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 0, 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, QFileDialog::ShowDirsOnly must be set.
On Windows, Mac OS X and Symbian^3, this static function will use the native file dialog and not a QFileDialog. On Windows CE, if the device has no native file dialog, a QFileDialog will be used.
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 0 then it will position the dialog just below the parent's title bar.
On Symbian^3 the options parameter is only used to define if the native file dialog is used.

The function creates a modal file dialog with the given parent widget. If parent is not 0, the dialog will be shown centered over the 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:
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.
The dialog's caption is set to caption. If caption is not specified then a default caption will be used.
On Windows, Mac OS X and Symbian^3, this static function will use the native file dialog and not a QFileDialog.
On Windows the dialog will spin a blocking modal event loop that will not dispatch any QTimers, and if parent is not 0 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.
On Symbian^3 the parameter selectedFilter has no meaning and the options parameter is only used to define if the native file dialog is used.

This is a convenience static function that will return one or more existing files selected by the user.
This function creates a modal file dialog with the given parent widget. If parent is not 0, the dialog will be shown centered over the parent widget.
The file dialog's working directory will be set to dir. If dir includes a file name, the file will be selected. The filter is set to filter so that only those files which match the filter are shown. The filter selected is set to selectedFilter. The parameters dir, selectedFilter and filter may be empty strings. If you need multiple filters, separate them with ';;', for instance:
