TitledBorder问题与物质用户界面和自定义JComponent

我正在使用BorderFactory创建一个带物质UI主题的Swing用户界面的标题边界，并且我遇到了下面显示的异常。我尝试了LineBorder，它的工作原理很完美，但似乎物质UI在某种程度上干扰了TitledBorder。TitledBorder问题与物质用户界面和自定义JComponent

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

本身可能不正确：边框绘制在paintComponent通过完成。我的问题基本上是如何得到TitledBorder而不创建父母JPanel，并将其设置，这似乎有点cop-out。

你试图添加边界到什么组件？这是否发生在所有组件上？你说这不会发生在'JPanel's ... – BoffinbraiN 2011-04-18 23:59:53

JComponent的一个子类:) – 2011-04-19 12:31:47

你可能会得到更多的运气，直接向Substance团队报告，以便他们可以进行调查，或至少提出一种解决方法。我假设如果使用默认的LaF，问题就会消失。 – BoffinbraiN 2011-04-19 16:09:17

这是laf-widget肠子深处的一个bug。它目前假定每个Graphics对象都有一个GraphicsConfiguration和一个GraphicsDevice与之关联。我有一个名为insubstantial的物质分支，即has a fix。

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列车。

当然:)顺便说一下，我正在考虑切换到非实体。 – 2011-05-25 23:05:44

我会将此标记为已接受，因为Substance不再被使用。 – 2011-05-25 23:09:30
