java - 非法参数异常 : No interpolator found for float during implementing Substance LAF

Question

我尝试过实现 Substance LAF。我还下载了 Trident 库。应用程序通常会启动(从包结构中选择 LAF)，但是当我尝试在 JMenuBar 中使用菜单时，出现以下异常。

我发现了非常相似的问题，但它绝对是不同的 – Flamingo ribbon: Java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float 。

有什么想法吗？

Answer 1

经过几个小时的努力，我找到了解决方案。错误

java.lang.IllegalArgumentException: No interpolator found for java.lang.Float:java.lang.Float

与TimelinePropertyBuilder类中的代码无关。 它缺少相应顶级库的META-INF中的trident-plugin.properties文件。确切地定义了Interpolator类源。

因此，无需寻找它，这里是非常需要的 trident-plugin.properties:

UIToolkitHandler=org.pushingpixels.trident.swing.SwingToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swing.AWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.swt.SWTToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.swt.SWTPropertyInterpolators

UIToolkitHandler=org.pushingpixels.trident.android.AndroidToolkitHandler
PropertyInterpolatorSource=org.pushingpixels.trident.android.AndroidPropertyInterpolators

PropertyInterpolatorSource=org.pushingpixels.trident.interpolator.CorePropertyInterpolators

这应该可以解决问题。
