[quote=引用 18 楼 Gaowen_HAN 的回复:] 利用 Synth 可以创建出完全专业的外观，Java 1.4 中发布的 GTK+ 和 Windows XP 外观就完全是用 Synth 创建的。（那时它不是一个已公布的 API。） 由于我上面的例子实践中用了20张png图片，加载速度以及内存占用比Metal的L&F可能差一点，不过如果是复杂界面或者创建数量多的Components时，Synth和Metal还是差不多的。比如，我这个例子中（XP + JDK7u45 + Eclipse Kepler）如果注销掉
initLookAndFeel();// specify the L&F
这行代码，得到的Metal经典外观时占用的内存为25Kb，如果不注销，使用的定制的外观时内存为29Kb，这些内存和启动速度我觉得都比JavaFX应用要好。 如果使用100 个组件的界面来测试：

遇到一个问题： 当使用自定义感官时，比如我上面的L&F或者使用jgoodies的UIManager.setLookAndFeel(new com.jgoodies.looks.windows.WindowsLookAndFeel()); 则如果定义文本框等，像JTextField,JTextPane时，在用智能拼音输入时，输入窗口会出现方框形式的乱码。取消这种观感的设置既可解决问题（比如注销掉initLookAndFeel();// specify the L&F）。原因是这种观感不支持中文。怎么让自定义的感官支持呢？

解决了，是因为字体的原因，Arial不支持中文的显示。改为雅黑就行了，可以使用Component的getFont()以及Font的canDisplay(int codePoint)或者canDisplayUpTo(String)来判断是否支持特定的字符显示。
