Question

有没有办法在JInternalFrame图标菜单中添加/删除项目（这就是它的名称？）？

enter image description here

感谢@camickr，我能够使用Swing Utils深入挖掘UIManager。我发现的是：我打印出了Nimbus LookAndFeel HashMap

    for(Entry<Object, Object> entry : SwingUtils.getUIDefaultsOfClass(JInternalFrame.class).entrySet()) {
        System.out.println(entry.getKey().toString() + " ----------- " + entry.getValue().toString());
        System.out.println("*********************************");
    }

这就是出现的情况：

Answer 1

不要以为你可以删除它们（没有创建你自己的自定义UI，这对我来说太复杂了。）

你应该可以禁用它们。查看JInternalFrame API构造函数，了解将属性设置为false的方法。或者，您可以使用setter方法单独禁用给定属性。

编辑：

注意到Windows上的默认LAF没有该菜单，所以肯定是LAF问题。

编辑2：

也许作为一个黑客你可以使用Darryl的Swing Utils来获取为内部框架定义的所有JMenuItem组件的List。然后，您可以简单地从其父JMenu中删除菜单项。

编辑3：

我建议获取JMenuItem组件的列表，而不是UIDefaults。这假设BasicInternalFrameUI使用了JMenuBar，JMenu和JMenuItems。这个假设是正确的。

事实证明，Metal LAF扩展了基本的LAF，并没有将JMenubar添加到内部框架的标题窗格中。相反，只需在左上角绘制一个图标，解释为什么没有系统菜单。

但是，Windows LAF实际上使用自定义绘制的JLabel来显示系统菜单的图标，然后只响应mousePressed事件以显示弹出菜单。因此，对于Window LAF，您可以使用SwingUtils查找此标签，只需从标签中删除MouseListener即可。下面的“框架”变量是您的内部框架。

java.util.List<JLabel> labels = SwingUtils.getDescendantsOfType(JLabel.class, frame, true);

for (JLabel label: labels)
{
    System.out.println(label.getClass().getName());

    MouseListener[] ml = (MouseListener[])label.getListeners(MouseListener.class);

    for (int i = 0; i < ml.length; i++)
        label.removeMouseListener( ml[i] );
}

正如我之前提到的，这实际上只是一个黑客，应该不会被使用，因为它不是一个跨平台的解决方案。
