Swing UIManager.getColor（）键

Question

Swing的UIManager.getColor()键有一个列表吗？我似乎无法在网上找到它，只是偶尔引用像"Panel.background"和"Table.selectionBackground"这样的字符串。

Answer 1

我一直在寻找同样的事情，并找到了这个网页，以及所有这些特性对http://nadeausoftware.com/node/85了很好的概述。

Answer 2

他们是一种外观和感觉实施依赖。在BasicLookAndFeel.java查看基本密钥。不要指望所有PL & F的行为相同，甚至在版本之间保持不变。

Answer 3

我不认为有一个定义的标准的一组密钥。但你可以尝试这段代码可以列出当前按字母顺序排列的可用的：

List<String> colors = new ArrayList<String>(); 
for (Map.Entry<Object, Object> 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); 

这就产生太长，这里再现列表。

@ mmyers让我受到启发。这里有一个简短的程序，列出可排序表中的UIManager默认值。

这个节目是我见过的可视化UIManager的值最好的（如字体，颜色，边框）：http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/

它缺乏的搜索，但它可以通过组件或值类型，这是非常伟大的过滤器。
