Windows 上是否有用于 SWT 的新行命令？如果没有，我在这里做错了什么？

这是代码

    public static void main (String [] args) {
    Display display = new Display();
    Shell shell = new TabsTest().createShell(display);
    shell.setSize(350,500);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch())
            display.sleep();
    }
}

private Shell createShell(final Display display) {
    final Shell shell = new Shell(display);
    shell.setText("Betting Tracker");

    //Creating grid layout, used to organize the shell
    GridLayout gridLayout = new GridLayout();
    gridLayout.numColumns = 20;
    shell.setLayout(gridLayout);

    //Grid1
    GridData gridData = new GridData(GridData.FILL, GridData.CENTER, true, false);
    gridData.horizontalSpan = 20;

    new Label(shell, SWT.NONE).setText("Bet Type:");
        betType = new Combo(shell, SWT.SINGLE | SWT.BORDER);
        betType.setItems(new String[] {"   ", "NFL", "NBA", "CFB"});
        betType.setLayoutData(gridData);

    //Grid2
    GridData gridData2 = new GridData(GridData.BEGINNING, GridData.CENTER, true, false);
    gridData2.widthHint = 20;   
    gridData2.horizontalSpan = 5;

    new Label(shell, SWT.NONE).setText("Bets Played:");
        numBets = new Text(shell, SWT.NONE);
        numBets.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, false));
        numBets.setLayoutData(gridData2);

    new Label(shell, SWT.NONE).setText("    Won:  ");
        betsWon = new Text(shell, SWT.NONE);
        betsWon.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, false));
        betsWon.setLayoutData(gridData2);

    new Label(shell, SWT.NONE).setText("    Lost:  ");
        betsWon = new Text(shell, SWT.FILL);
        betsWon.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, true));
        betsWon.setLayoutData(gridData2);   

    //Grid3
    GridData gridData3 = new GridData(GridData.CENTER, GridData.CENTER, true, false);
    gridData3.horizontalSpan = 20;

    new Label(shell, SWT.NONE).setText("Todays Lines");
        lines = new List(shell, SWT.MULTI | SWT.BORDER | SWT.V_SCROLL);
        lines.setItems(new String[] { "OKC(+2.5) - MIA(-2.5)", "DAL(+8) - BOS(-8)" });
        int listHeight = lines.getItemHeight() * 12;
        trim = lines.computeTrim(0, 0, 0, listHeight);
        gridData3.heightHint = trim.height;
        lines.setLayoutData(gridData3);

    return shell;
}

}

问题是我在 //Grid3 注释下创建了一个新标签。该标签贴在它上面的行上，而不是出现在新行上。我是 SWT 的新人，所以我知道这只是我缺乏知识。我会附上一张图片，以便您查看问题。

您可以看到标签“Todays Lines：”不在它自己的行上。

任何帮助将不胜感激！

您不止一次分配文本的布局数据，首先分配给new GridData()then gridData2。一次就够了。新标签未出现在新行上的原因是网格有 20 列，如gridLayout.numColumns = 20;. gridData2有horizontalSpan = 5。如果添加 3 个标签（默认跨越 1 列）和跨越 5 列的三个文本（gridData2按照

我建议为GridData文本分配单独的实例，并将跨越它们的列数划分为总计 20（例如，最后一个跨越不是 5 列而是 7 列），这样“今天的行”将被放置在下一行.
