更改JTabbedPanel侧视图的颜色

问题描述 投票:0回答:1

我正在使用JTabbedPane设计以下布局,并希望更改突出显示部分的颜色。但是我没有办法做到这一点。我的问题如何改变背景色?我尝试了什么?我试过更改JPanel和JTabbedPane的background-colorForeground-color,但运气不佳。我还在从属性中保留Opaque = false的同时尝试了此操作,但是没有运气。jTabbedPane1.setForegroundAt(1, Color.yellow); jTabbedPane1.setForegroundAt(2, Color.yellow);

this layout更新1

 String[] tabNames = {"Signin", "General", "Call Rate", "Audio Device","tab 5","tab 6","tab 7","tab 8","tab 9"};

    for (int i = 0; i < tabNames.length; i++) {
        JLabel lab = new JLabel("<html><font color=white>" + tabNames[i] + "</font></html>", SwingConstants.CENTER);

        lab.setForeground(Color.red);
        lab.setBackground(Color.BLUE);
        lab.setPreferredSize(new Dimension(200, 50));
        lab.setFont(new Font("Times New Roman", Font.BOLD, 22));
        jTabbedPane1.setTabComponentAt(i, lab);
    }

    for (int i = 0; i < this.jTabbedPane1.getTabCount(); i++) {
        jTabbedPane1.setBackgroundAt(i,Color.DARK_GRAY);
    }

我尝试添加JLabel来更改显示我的标签名称的组件的大小,然后尝试设置setBackgroundAt。它既不起作用,也不对Label起作用setBackgroundsetForeground我的外观

  try {

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

    } catch (ClassNotFoundException | InstantiationException | IllegalAccessException | javax.swing.UnsupportedLookAndFeelException ex) {
        java.util.logging.Logger.getLogger(Settings.class.getName()).log(java.util.logging.Level.SEVERE, null, ex);
    }

基本逻辑是:

JPanel tab1 = new JPanel();
tab1.background( Color.RED );

JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.add(tab1, "Tab1");

JPanel parent = new JPanel( new BorderLayout() );
parent.setBackground( Color.GREEN );
parent.add( tabbedPane );

frame.add( parent );

现在选项卡占用的区域将具有“父”面板的背景颜色。

如果这不起作用,则说明外观问题。
