JScrollpane在jscrollpane-jpanel上

Question

我想将多个jscrollpane jpanel添加到jscrollpane jpanel

在我想要隐藏它们的5个项目之后。所以我需要滚动才能看到它们。

这可能吗？如果是，我该怎么做？

这是我编写的用于制作布局和testcenario的代码。

这应该可以正常工作。

        for (int i = 0; i < subtitles.size() - 1; i++) {
            languageSelectionPanel.add(subtitles.get(i), gbc);
        }
        gbc.gridx = 0;
