使用Substance UI和自定义JComponent时的TitledBorder问题

我正在使用BorderFactory创建一个带有Substance UI主题的Swing用户界面的标题边框，但我遇到了下面显示的异常。我尝试使用LineBorder，它完美地工作，但似乎Substance UI在某种程度上干扰了TitledBorder。边框绘制通过paintComponent完成：
if (getBorder() != null) {
   getBorder().paintBorder(this, g, 0, 0, getWidth(), getHeight());
}

它本身可能是不正确的。我的问题实质上是如何在不创建父JPanel并将其设置在上面的情况下使TitledBorder正常工作，这似乎有点像一种逃避责任的做法。

Thanks in advance for any help.

你想要给哪个组件添加边框？所有的组件都会出现这种情况吗？你说这种情况不会发生在 JPanel 上... - BoffinBrain

你可以直接向Substance团队报告此问题，以便他们进行调查或至少提供解决方法。我假设如果您使用默认的LaF，则问题会消失。 - BoffinBrain
你解决了这个问题吗？有进展了吗？也许你能提供一个SSCCE来说明这个问题吗？我想试一下。 - Boro
我通过将组件放入面板中，并给该面板加上边框，来解决了这个问题 :) - Chris Dennett

当然 :) 顺便说一下，我也在考虑转换到Insubstantial。 - Chris Dennett
