爪哇光环外观

Question

我使用的是RSyntaxTextArea，它最终扩展自JTextArea。当我将look and feel更改为Nimbus时，文本区域不会像GUI的其他部分那样受到影响，这看起来不太好。

这是我使用的Nimbus主题代码：

import javax.swing.*;
import java.awt.*;

import static javax.swing.SwingUtilities.updateComponentTreeUI;
import static javax.swing.UIManager.*;

public class SwingLookAndFeel
{
    static void setDarkNimbusLookAndFeel(JFrame frame) throws Exception
    {
        put("control", new Color(128, 128, 128));
        put("info", new Color(128, 128, 128));
        put("nimbusBase", new Color(18, 30, 49));
        put("nimbusAlertYellow", new Color(248, 187, 0));
        put("nimbusDisabledText", new Color(128, 128, 128));
        put("nimbusFocus", new Color(115, 164, 209));
        put("nimbusGreen", new Color(176, 179, 50));
        put("nimbusInfoBlue", new Color(66, 139, 221));
        put("nimbusLightBackground", new Color(18, 30, 49));
        put("nimbusOrange", new Color(191, 98, 4));
        put("nimbusRed", new Color(169, 46, 34));
        put("nimbusSelectedText", new Color(255, 255, 255));
        put("nimbusSelectionBackground", new Color(104, 93, 156));
        put("text", new Color(230, 230, 230));

        for (LookAndFeelInfo[] info : getInstalledLookAndFeels())
        {
            if ("Nimbus".equals(info.getName()))
            {
                setLookAndFeel(info.getClassName());
                break;
            }
        }

        refreshFrame(frame);
    }

    private static void refreshFrame(JFrame frame)
    {
        if (frame != null)
        {
            updateComponentTreeUI(frame);
            // frame.pack();
        }
    }
}

我想知道需要哪个UIManager键来修改文本区域的背景色，例如，将左侧JTree中的紫色设置为背景色，而不是白色？

下面是我找到的UIManager键的列表，但在这种情况下，它们中有没有哪一个有用？

下面介绍了如何专门为RSyntaxTextArea使用主题。使用提供的暗色。xml很好用：

private void changeStyleViaThemeXml() {
  try {
     Theme theme = Theme.load(getClass().getResourceAsStream(
           "/org/fife/ui/rsyntaxtextarea/themes/dark.xml"));
     theme.apply(textArea);
  } catch (IOException ioe) { // Never happens
     ioe.printStackTrace();
  }
}
