- * SECTION:gtkfilechooserbutton
- * @Short_description: A button to launch a file chooser dialog
- * @Title: GtkFileChooserButton
- * @See_also:#GtkFileChooserDialog
- *
- * The #GtkFileChooserButton is a widget that lets the user select a
- * file. It implements the #GtkFileChooser interface. Visually, it is a
- * file name with a button to bring up a #GtkFileChooserDialog.
- * The user can then use that dialog to change the file associated with
- * that button. This widget does not support setting the
- * #GtkFileChooser:select-multiple property to %TRUE.
- *
- * ## Create a button to let the user select a file in /etc
- *
- * |[<!-- language="C" -->
- * {
- * GtkWidget *button;
- * GFile *cwd = g_file_new_for_path ("/etc");
- *
- * button = gtk_file_chooser_button_new (_("Select a file"),
- * GTK_FILE_CHOOSER_ACTION_OPEN);
- * gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button), cwd, NULL);
- * g_object_unref (cwd);
- * }
- * ]|
- *
- * The #GtkFileChooserButton supports the #GtkFileChooserActions
- * %GTK_FILE_CHOOSER_ACTION_OPEN and %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
- *
- * > The #GtkFileChooserButton will ellipsize the label, and will thus
- * > request little horizontal space. To give the button more space,
- * > you should call gtk_widget_get_preferred_size(),
- * > gtk_file_chooser_button_set_width_chars(), or pack the button in
- * > such a way that other interface elements give space to the
- * > widget.
- *
- * # CSS nodes
- *
- * GtkFileChooserButton has a single CSS node with the name “filechooserbutton”.
