Swing UIManager.getColor（）键
是否有一个用于Swing的UIManager.getColor()键的列表？ 我似乎无法在网上找到它，只是偶尔引用字符串，如"Panel.background"和"Table.selectionBackground" "Panel.background" "Table.selectionBackground" 。
我正在寻找相同的东西，并在http://nadeausoftware.com/node/85上找到了这个页面以及所有这些属性的绝佳概述。
我认为没有定义的标准密钥集。 但您可以尝试使用这段代码按字母顺序列出当前可用的代码：
List colors = new ArrayList (); for (Map.Entry entry : UIManager.getDefaults().entrySet()) { if (entry.getValue() instanceof Color) { colors.add((String) entry.getKey()); // all the keys are strings } } Collections.sort(colors); for (String name : colors) System.out.println(name);
这会产生一个列表太长而无法在此重现。
@mmyers给了我灵感。 这是一个简短的程序，用于列出可排序表中的UIManager默认值。

这个程序是我见过的最好的可视化UIManager值（例如字体，颜色，边框）： http ： //tips4java.wordpress.com/2008/10/09/uimanager-defaults/
它缺少搜索，但它可以按组件或值类型进行过滤，这非常好。
它们依赖于外观和外观。 在BasicLookAndFeel.java查找基本键。 不要指望所有PL＆F的行为都相同，甚至在版本之间保持不变。
