Question

我试图在java swing中构建小应用程序。我开始使用此链接：Creating a Grid in Java。

一切都很好。我完成了那个任务，但是我正试图删除多余的标题边框。我试图减少标题边框的边界仍然不影响。任何有良好建议的人都试着与我分享。

我找到了你的问题，您将scrollPane添加到panel2为

panel2.add(scrollPane1, BorderLayout.CENTER);

但你没有将setLayout设置为panel2的BorderLayout。并将panel1的布局设置为null 看到这段代码

            JPanel panel1 = new JPanel();
            panel1.setLayout(null);//add to your code
            JPanel panel2 = new JPanel();
            panel2.setLayout(new BorderLayout());//add to your code
            panel2.setBounds(0,0,800,120);//add to your code
