我已经下载了quaqua 8软件包。我将其解压缩，并将quaqua.jar文件放在项目的工作库中。
然后在主要方法中我应用了quaqua的外观和感觉。但是我说ch.randelshofer.quaqua package doesn't exist时出错了。为什么会这样？
我还需要做什么吗？
也列在编译库中：
我使用的ide是netbeans，操作系统是windows。
最佳答案
从netbeans/win os/same import输出到库；quaqua left，mac os x right。

Quaqua Look and Feel官方页面上的注意事项：
Supported Platforms
The Quaqua Look and Feel supports Apple's J2SE 1.4, J2SE 5 and J2SE 6
and SoyLatte J2SE 6 on Mac OS X 10.4 and 10.5.
Altough Quaqua works with J2SE 6, it provides limited support for features
which go beyond J2SE 5.
The Quaqua native libraries support PowerPC and Intel Macs with 32-bits
or 64-bit processors. Quaqua will work without these native libraries,
but user experience degrades.
Due to copyright restrictions and technical constraints, Quaqua can be
run on non-Mac OS X systems for development purposes only.
FAQ
Can I use Quaqua on other platforms than Mac OS X?
No, you can't, except for development purposes.
This is because the Aqua user interface can only be licensed from Apple
for use on Mac OS X.
Even if Apple would license it for use on other platforms, you wouldn't
want to do it if you care about your users.
Aqua does not just look different than other user interfaces, it feels
different as well. For example, when compared with the Windows UX
interface, differences can be found in the set of keyboard accelerators,
the focus behavior, the selection behavior, the modality of dialogs and
in the use of transition and animation effects.
