  62  * @Short_description: A button to launch a file selection dialog
  63  * @Title: GtkFileChooserButton
  64  * @See_also:#GtkFileChooserDialog
  65  *
  66  * The #GtkFileChooserButton is a widget that lets the user select a
  67  * file.  It implements the #GtkFileChooser interface.  Visually, it is a
  68  * file name with a button to bring up a #GtkFileChooserDialog.
  69  * The user can then use that dialog to change the file associated with
  70  * that button.  This widget does not support setting the
  71  * #GtkFileChooser:select-multiple property to %TRUE.
  72  *
  73  * <example>
  74  * <title>Create a button to let the user select a file in /etc</title>
  75  * <programlisting>
  76  * {
  77  *   GtkWidget *button;
  78  *
  79  *   button = gtk_file_chooser_button_new (_("Select a file"),
  80  *                                         GTK_FILE_CHOOSER_ACTION_OPEN);
  81  *   gtk_file_chooser_set_current_folder (GTK_FILE_CHOOSER (button),
  82  *                                        "/etc");
  83  * }
  84  * </programlisting>
  85  * </example>
  86  *
  87  * The #GtkFileChooserButton supports the #GtkFileChooserAction<!-- -->s
  88  * %GTK_FILE_CHOOSER_ACTION_OPEN and %GTK_FILE_CHOOSER_ACTION_SELECT_FOLDER.
  89  *
  90  * <important>
  91  * The #GtkFileChooserButton will ellipsize the label,
  92  * and thus will thus request little horizontal space.  To give the button
  93  * more space, you should call gtk_widget_get_preferred_size(),
  94  * gtk_file_chooser_button_set_width_chars(), or pack the button in
  95  * such a way that other interface elements give space to the widget.
  96  * </important>
