Swing的UIManager.getColor()
鍵有一個列表嗎?我似乎無法在網上找到它,只是偶爾引用像"Panel.background"
和"Table.selectionBackground"
這樣的字符串。Swing UIManager.getColor()鍵
回答
我一直在尋找同樣的事情,並找到了這個網頁,以及所有這些特性對http://nadeausoftware.com/node/85了很好的概述。
他們是一種外觀和感覺實施依賴。在BasicLookAndFeel.java
查看基本密鑰。不要指望所有PL & F的行爲相同,甚至在版本之間保持不變。
我不認爲有一個定義的標準的一組密鑰。但你可以嘗試這段代碼可以列出當前按字母順序排列的可用的:
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);
這就產生太長,這裏再現列表。
目前(jdk1.8.0_45),用於`systemLookAndFeelClassName = com。 sun.java.swing.plaf.windows.WindowsLookAndFeel`,類不是`java.awt.Color`,而是`com.sun.java.swing.plaf.windows.DesktopProperty`,不幸的是,instanceof檢查失敗。 – 2015-06-24 19:51:39
@ mmyers讓我受到啓發。這裏有一個簡短的程序,列出可排序表中的UIManager默認值。

在NetBeans GUI構建器中,編輯顏色時,您可以從列表中選擇所有列表(不包含實際顏色值)。這實際上是我認爲有可能列出它們的想法。不過,表格更好。 – 2009-04-09 14:22:20
這個節目是我見過的可視化UIManager的值最好的(如字體,顏色,邊框):http://tips4java.wordpress.com/2008/10/09/uimanager-defaults/
它缺乏的搜索,但它可以通過組件或值類型,這是非常偉大的過濾器。
