    JPanel Tryck = new JPanel();

    main.setLayout(new GridLayout(1,1));
    p.setLayout(c1);

    this.add(main);

    main.add(scrollpane);

    p.add(Mekanik, "1");
    p.add(Tryck, "2");
    c1.show(p, "1");

当我添加更多的图片时，我希望它们从左到右填充，直到一行被填充，然后填充下一行。目前，它只是继续填补第一行。
如果我加上

scrollpane.setHorizontalScrollBarPolicy(HORIZONTAL_SCROLLBAR_NEVER);

它只是删除了水平滚动条，但图片仍然在一行结束。
我不知道怎么了。谢谢你的帮助！
