java - 覆盖 Nimbus 颜色

我们正在使用 Nimbus LaF 开发一个 Swing 应用程序。我们更改了许多 Nimbus 默认设置(控件、文本、NimbusLightBackground 等)以拥有深色主题。

现在我们在渲染 JLists 和 JComboBoxes 时遇到了很大的麻烦，因为渲染器显然对选定的文本前景使用了 NimbusLightBackground 颜色。这会导致深蓝色背景上出现深灰色文本 - 不好。

我已经尝试通过 UIManager.putDefault() 和每个组件覆盖全局覆盖 Nimbus Defaults 中任何看似适用的键(“ComboBox:\”ComboBox.listRenderer\“[Selected].textForeground”等)，但根本无法找零。

即使是 SwingX 荧光笔似乎也无法覆盖此行为，至少在组合框下拉列表中是这样。

关于如何为 J(X)List 和 J(X)ComboBox Dropdowns 设置选定文本前景色有什么想法吗？

我对每个组件覆盖的最新尝试:

JXComboBox comboBox = new JXComboBox();
UIDefaults comboBoxTheme = new UIDefaults();
comboBoxTheme.put("nimbusLightBackground", new Color(0xFFFAFA));
comboBoxTheme.put("ComboBox:\"ComboBox.listRenderer\"[Selected].textForeground", new Color(0xFFFAFA));
comboBox.putClientProperty("Nimbus.Overrides.InheritDefaults", true);
comboBox.putClientProperty("Nimbus.Overrides", comboBoxTheme);
SwingUtilities.updateComponentTreeUI(comboBox);

应用程序范围的 nimbus 默认值:

ColorUIResource backgroundUI = new ColorUIResource(0x494949);
ColorUIResource textUI = new ColorUIResource(0xFFFAFA);
ColorUIResource controlBackgroundUI = new ColorUIResource(0x5F5F4D);
ColorUIResource infoBackgroundUI = new ColorUIResource(0x2f5cb4);
ColorUIResource infoUI = new ColorUIResource(0x2f5cb4);
ColorUIResource lightBackgroundUI = new ColorUIResource(0x5D5D5B);
ColorUIResource focusUI = new ColorUIResource(0x39698a);

UIManager.put("control", backgroundUI);
UIManager.put("text", textUI);
UIManager.put("nimbusLightBackground", lightBackgroundUI);
UIManager.put("info", infoUI);
UIManager.put("nimbusInfoBlue", infoBackgroundUI);
UIManager.put("nimbusBase", controlBackgroundUI);
UIManager.put("nimbusBlueGrey", controlBackgroundUI);
UIManager.put("nimbusFocus", focusUI);

全部在 Java 7u55 中实现，但我怀疑这是否重要，因为似乎没有人维护 Swing/Nimbus 已经有一段时间了。

PS:我当然读过this question和其他人，但尚未找到有效的答案。

编辑:这是一个演示问题的 SSCCE。它创建一个 JFrame，顶部有一个仅默认的组合框，中间有一个列表，底部有一个每个组件覆盖的组合框。在列表中或从框下拉列表中选择一个值时，可以看到该问题。

package sscce;

import java.awt.BorderLayout;
import java.awt.Color;

import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JList;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
import javax.swing.UIDefaults;
import javax.swing.UIManager;
import javax.swing.UIManager.LookAndFeelInfo;
import javax.swing.plaf.ColorUIResource;

public class ForegroundProblemDemo extends JFrame {

public ForegroundProblemDemo() {
    super("Demo");
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    JComboBox<String> comboBoxWithDefaults = createComboBox();
    JComboBox<String> comboBoxWithOverrides = createComboBox();
    JList<String> list = createList();
    addOverrides(comboBoxWithOverrides);

    getContentPane().setLayout(new BorderLayout());
    getContentPane().add(new JScrollPane(list), BorderLayout.CENTER);
    getContentPane().add(comboBoxWithDefaults, BorderLayout.NORTH);
    getContentPane().add(comboBoxWithOverrides, BorderLayout.SOUTH);

    pack();
    setLocationRelativeTo(null);
    setVisible(true);
}

JComboBox<String> createComboBox() {
    JComboBox<String> comboBox = new JComboBox<>(new String[] {"A","B","C","D"});
    return comboBox;
}

JList<String> createList() {
    JList<String> list = new JList<>(new String[] {"A","B","C","D"});
    return list;
}

void addOverrides(JComponent component) {
    UIDefaults theme = new UIDefaults();
    theme.put("nimbusLightBackground", new Color(0xFFFAFA));
    theme.put("ComboBox:\"ComboBox.listRenderer\"[Selected].textForeground", new Color(0xFFFAFA));
    component.putClientProperty("Nimbus.Overrides.InheritDefaults", true);
    component.putClientProperty("Nimbus.Overrides", theme);
    SwingUtilities.updateComponentTreeUI(component);
}


public static void main(String... args) throws Throwable {
    ColorUIResource backgroundUI = new ColorUIResource(0x494949);
    ColorUIResource textUI = new ColorUIResource(0xFFFAFA);
    ColorUIResource controlBackgroundUI = new ColorUIResource(0x5F5F4D);
    ColorUIResource infoBackgroundUI = new ColorUIResource(0x2f5cb4);
    ColorUIResource infoUI = new ColorUIResource(0x2f5cb4);
    ColorUIResource lightBackgroundUI = new ColorUIResource(0x5D5D5B);
    ColorUIResource focusUI = new ColorUIResource(0x39698a);
    UIManager.put("control", backgroundUI);
    UIManager.put("text", textUI);
    UIManager.put("nimbusLightBackground", lightBackgroundUI);
    UIManager.put("info", infoUI);
    UIManager.put("nimbusInfoBlue", infoBackgroundUI);
    UIManager.put("nimbusBase", controlBackgroundUI);
    UIManager.put("nimbusBlueGrey", controlBackgroundUI);
    UIManager.put("nimbusFocus", focusUI);

    for (LookAndFeelInfo lafInfo : UIManager.getInstalledLookAndFeels()) {
        if ("Nimbus".equals(lafInfo.getName())) {
            UIManager.setLookAndFeel(lafInfo.getClassName());
            break;
        }
    }

    new ForegroundProblemDemo();
}

}

编辑 2:抱歉，之前应该提到这一点:对于列表，使用 setSelectionForeground() 方法可以轻松解决问题。对于组合框，我还没有找到缺少自定义渲染器的方法。所以我在这里的主要重点是组合框。

  • 看看会发生什么，Win8.1 64b、Java7、JDK 1.7_021，通过使用全矩形 Painter，

  • 如果不使用 XxxRenderer 就什么都不会发生，然后可以为可编辑和不可编辑的 JComboBox(具有相同的颜色主题)创建漂亮的主题

  • 我会看看 Seaglas L&F(注意需要在 JDK 1.6._Xxx 中编译)

enter image description here 

import java.awt.*;
import java.util.Vector;
import javax.swing.*;
import javax.swing.UIManager;

public class MyComboBox {

    private Vector<String> listSomeString = new Vector<String>();
    private JComboBox someComboBox = new JComboBox(listSomeString);
    private JComboBox editableComboBox = new JComboBox(listSomeString);
    private JComboBox non_EditableComboBox = new JComboBox(listSomeString);
    private JFrame frame;

    public MyComboBox() {
        listSomeString.add("-");
        listSomeString.add("Snowboarding");
        listSomeString.add("Rowing");
        listSomeString.add("Knitting");
        listSomeString.add("Speed reading");
        someComboBox.setPrototypeDisplayValue("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
        someComboBox.setFont(new Font("Serif", Font.BOLD, 16));
        someComboBox.setEditable(true);
        someComboBox.getEditor().getEditorComponent().setBackground(Color.YELLOW);
        ((JTextField) someComboBox.getEditor().getEditorComponent()).setBackground(Color.YELLOW);
        editableComboBox.setPrototypeDisplayValue("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
        editableComboBox.setFont(new Font("Serif", Font.BOLD, 16));
        editableComboBox.setEditable(true);
        JTextField text = ((JTextField) editableComboBox.getEditor().getEditorComponent());
        text.setBackground(Color.YELLOW);
        non_EditableComboBox.setPrototypeDisplayValue("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
        non_EditableComboBox.setFont(new Font("Serif", Font.BOLD, 16));
        frame = new JFrame();
        frame.setLayout(new GridLayout(0, 1, 10, 10));
        frame.add(someComboBox);
        frame.add(editableComboBox);
        frame.add(non_EditableComboBox);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLocation(100, 100);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        try {
            UIManager.setLookAndFeel("com.seaglasslookandfeel.SeaGlassLookAndFeel");
        } catch (Exception e) {
            e.printStackTrace();
        }
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                MyComboBox aCTF = new MyComboBox();
            }
        });
    }
}
