Java - GridBagLayout位置JLabel

Question

我使用GridBagLayout并在其上放置JLabel，如图所示。我设法通过JLabel和ipadx将ipady的大小设置为所需的大小，但我似乎无法使用它的位置。它看起来总是以中间为中心，而我想从红点开始并且在我调整窗口大小时不要重新定位。我该怎么办？

感谢。我使用的代码也是：

GridBagLayout gbl = new GridBagLayout();
setLayout(gbl);
GridBagConstraints gbc = new GridBagConstraints();

JLabel jl = new JLabel("This is a jlabel!", SwingConstants.CENTER);
jl.setBorder(BorderFactory.createLineBorder(Color.black));
gbc.fill = GridBagConstraints.HORIZONTAL;
gbc.ipadx = 87;
gbc.ipady = 220;
add(jl, gbc);

Answer 1

我对它进行了改进...现在你可以使用插图来标记Dimension d = new Dimension(350, 400); GridBagLayout gbl = new GridBagLayout(); JFrame frame = new JFrame("Heloo"); frame.setLayout(gbl); GridBagConstraints gbc = new GridBagConstraints(); JLabel jl = new JLabel("This is a jlabel!", SwingConstants.CENTER); jl.setBorder(BorderFactory.createLineBorder(Color.black)); gbc.ipadx = 87; gbc.ipady = 220; gbc.insets = new Insets(0, 0, 360, 340);// here work with JFrame size!! 周围的标签，但经过一些研究后我建议选择不同的layout manager。

所以你的代码看起来像是：

SELECT
   DATEDIFF(d, ts.minimum, ts.maximum)/ ts.EntryAmount as Frequency
   ,ts.column1, ts.column2, ts.column3, ts.column4
FROM
(
    SELECT
        COUNT(*) as EntryAmount,
        max(Date) AS maximum,
        min(Date) AS minimum,
        column1, column2, column3, column4
    FROM Times
    GROUP BY column1, column2, column3, column4
    HAVING COUNT(*) > 1
) ts

希望此代码能为您提供帮助：）
