我不熟悉在 Java 中使用外观。我试图将 Seaglass 的外观添加到我正在处理的 Java 应用程序中，但我似乎无法弄清楚如何使用它。我发现其他人在使用它时也遇到了问题，尽管他们说已经解决了。
这是我的 Java 代码(我使用的是 Netbeans 8.1 Beta):

/**

*/
public MainProgram() {

}

* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.

我的源包中有 seaglasslookandfeel-0.2.jar。
例如
Source Packages
-pamsorganizer
-MainProgram.java
-seaglasslookandfeel-0.2.jar
所以我的问题是，是否有人可以帮助我让 Seaglass 在我的 Java 应用程序中工作。我的错误如下:

最佳答案
将它添加到您的图书馆
只需在项目资源管理器中右键单击您的 Libraries 文件夹，然后添加 Jar/文件夹
它应该可以工作，我刚测试过。不过真的不需要测试，它每次都对我有用。
