Substance UI 和自定义 JComponent 的 TitledBorder 问题
我正在使用 BorderFactory 创建一个带有 Substance UI 主题 Swing 用户界面的标题边框，我遇到了如下所示的异常。我尝试使用 LineBorder 并且它工作得很好，但 Substance UI 似乎以某种方式干扰了 TitledBorder。边框绘制是在 paintComponent via: 中完成的，
if (getBorder() != null) {
getBorder().paintBorder(this, g, 0, 0, getWidth(), getHeight());
}
它本身可能是不正确的。我的问题本质上是如何在不创建父级 JPanel 并将其设置在其上的情况下让 TitledBorder 工作，这似乎有点逃避。

这是 laf-widget 内部深处的一个错误。目前假设每个 Graphics 对象都有一个 GraphicsConfiguration 和一个与其关联的 GraphicsDevice。我有一个名为 insubstantial 的物质分支 已解决此问题。
当前快照的 Maven 坐标已修复，为 com.github.insubstantial:substance:6.3-SNAPSHOT，快照存储库位于 https://oss.sonatype.org/content/repositories/snapshots/。我预计在 6 月底左右发布 6.3 版本。
This is a bug deep in the bowels of laf-widget. It currently assumes that every Graphics object has a GraphicsConfiguration and a GraphicsDevice associated with it. I have a fork of substance called insubstantial that has a fix for this.
The maven coordinates for the current snapshot this is fixed in are com.github.insubstantial:substance:6.3-SNAPSHOT and the snapshot repository is at https://oss.sonatype.org/content/repositories/snapshots/. I anticipate releasing the 6.3 train at or around the end of June.
