| /** |
| * <code>JToolBar</code> provides a component that is useful for |
| * displaying commonly used <code>Action</code>s or controls. |
| * For examples and information on using tool bars see |
| * <a href="http://docs.oracle.com/javase/tutorial/uiswing/components/toolbar.html">How to Use Tool Bars</a>, |
| * a section in <em>The Java Tutorial</em>. |
| * |
| * <p> |
| * With most look and feels, |
| * the user can drag out a tool bar into a separate window |
| * (unless the <code>floatable</code> property is set to <code>false</code>). |
| * For drag-out to work correctly, it is recommended that you add |
| * <code>JToolBar</code> instances to one of the four "sides" of a |
| * container whose layout manager is a <code>BorderLayout</code>, |
| * and do not add children to any of the other four "sides". |
| * <p> |
| * <strong>Warning:</strong> Swing is not thread safe. For more |
| * information see <a |
| * href="package-summary.html#threading">Swing's Threading |
| * Policy</a>. |
| * <p> |
| * <strong>Warning:</strong> |
| * Serialized objects of this class will not be compatible with |
| * future Swing releases. The current serialization support is |
| * appropriate for short term storage or RMI between applications running |
| * the same version of Swing. As of 1.4, support for long term storage |
| * of all JavaBeans™ |
| * has been added to the <code>java.beans</code> package. |
