标题为ui和自定义JOMPONENT的BORDER问题

Question

我在用着 BorderFactory 要创建具有UI主题的Swing用户界面的标题为“边框”，我遇到下面显示的例外。我尝试了 LineBorder 它的工作原理，但似乎UI的物质正在以某种方式干扰 TitledBorder. 。边框图是在 paintComponent 通过：

if (getBorder() != null) {
   getBorder().paintBorder(this, g, 0, 0, getWidth(), getHeight());
}

本身可能是不正确的。我的问题本质上是如何获得 TitledBorder 不创建父母的工作 JPanel 然后将其设置在上面，这似乎有点像个警察。

这是LAF-Widget的肠子深处的一个虫子。目前，它假设每个图形对象都有一个图形configuration和与之关联的GraphicsDevice。我有一个叫做的物质叉 毫无疑问 那 有一个修复 为了这。

当前快照的maven坐标已固定在com.github.github.insubstantial：物质：6.3-snapshot和快照存储库位于 https://oss.sonatype.org/content/repositories/snapshots/. 。我预计在6月底或周日左右会释放6.3列火车。
