java - 使用合成器自定义外观 JPogressBar 和 JSplitPane xml

Question

我正在尝试使用合成器使用 xml 文件为我的程序制作自定义外观，并且运行良好，但我不确定如何自定义 JProgressBar 或 JSplitPane。我在 JProgressBar 上有边框，没有任何问题，但我找不到如何自定义加载动画。顺便说一句，加载栏设置为不确定。就 SplitPane 而言，我唯一难以工作的是分割 Pane 拖动分隔线。分割 Pane 在程序中工作正常，只是当您拖动它时，分割线不会显示。这是我当前的 xml 文件。感谢您的帮助。

Answer 1

经过几个小时搜索 Synth 源代码后，我解决了这个问题。拆分的键为 SplitPaneDivider，进度条的键为 ProgressBar。相应的方法是 splitPaneDragDivider 和 progressBarForeground/Background。
