/**
|
||||
* An implementation of a radio button menu item.
|
||||
* A <code>JRadioButtonMenuItem</code> is
|
||||
* a menu item that is part of a group of menu items in which only one
|
||||
* item in the group can be selected. The selected item displays its
|
||||
* selected state. Selecting it causes any other selected item to
|
||||
* switch to the unselected state.
|
||||
* To control the selected state of a group of radio button menu items,
|
||||
* use a <code>ButtonGroup</code> object.
|
||||
* <p>
|
||||
* Menu items can be configured, and to some degree controlled, by
|
||||
* <code><a href="Action.html">Action</a></code>s. Using an
|
||||
* <code>Action</code> with a menu item has many benefits beyond directly
|
||||
* configuring a menu item. Refer to <a href="Action.html#buttonActions">
|
||||
* Swing Components Supporting <code>Action</code></a> for more
|
||||
* details, and you can find more information in <a
|
||||
* href="http://docs.oracle.com/javase/tutorial/uiswing/misc/action.html">How
|
||||
* to Use Actions</a>, a section in <em>The Java Tutorial</em>.
|
||||
* <p>
|
||||
* Some menus can have several button groups with radio button menu items. In
|
||||
* this case it is useful that clicking on one radio button menu item does not
|
||||
* close the menu. Such behavior can be controlled either by client
|
||||
* {@link JComponent#putClientProperty} or the Look and Feel
|
||||
* {@link UIManager#put} property named
|
||||
* {@code "RadioButtonMenuItem.doNotCloseOnMouseClick"}. The default value is
|
||||
* {@code false}. Setting the property to {@code true} prevents the menu from
|
||||
* closing when it is clicked by the mouse. If the client property is set its
|
||||
* value is always used; otherwise the {@literal L&F} property is queried.
|
||||
* Note: some {@code L&F}s may ignore this property. All built-in {@code L&F}s
|
||||
* inherit this behaviour.
|
||||
* <p>
|
||||
* For further documentation and examples see
|
||||
* <a
|
||||
href="http://docs.oracle.com/javase/tutorial/uiswing/components/menu.html">How to Use Menus</a>,
|
||||
* a section in <em>The Java Tutorial.</em>

||||

||||

|
||||
* 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.

||||
* Please see {@link java.beans.XMLEncoder}.
