java – MigLayout中的Span / Grow错误？

以下是接近我想要的,并做我期望的：

import javax.swing.JComboBox;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;

import net.miginfocom.swing.MigLayout;

public class MigBug extends JFrame {

    public static void main(String args[]) {
        MigBug migbug = new MigBug();
        migbug.pack();
        migbug.setVisible(true);
    }

    public MigBug() {
        JPanel content = new JPanel();
        content.setLayout(new MigLayout("fill, debug"));

        content.add(new JLabel("Label 1"));
        content.add(new JComboBox());

        content.add(new JLabel("Label 2"));
        content.add(new JTextField(25), "growx, wrap");

        content.add(new JLabel("BIG"), "span, w :400:, h :200:, growy");

        setContentPane(content);
    }
}

但是,如果我做出以下更改：

content.add(new JLabel("BIG"), "span, w :400:, h :200:, grow");

即.将跨区组件更改为在x和y中增长,Label 1单元格以x增长,即使它不应该.

有谁知道我可以解决这个问题？

解决方法:

找到了解决方法,但并不完全令人满意.根据this forum post和this forum post,MigLayout从计算组件大小切换到计算涉及跨度的列大小.在布局约束中用“filly”替换“fill”,然后为每个应该允许增长的列添加“增长”的列约束似乎可以修复它.

工作代码：

import javax.swing.JComboBox;
import javax.swing.JPanel;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextField;

import net.miginfocom.swing.MigLayout;

public class MigBug extends JFrame {

    public static void main(String args[]) {
        MigBug migbug = new MigBug();
        migbug.pack();
        migbug.setVisible(true);
    }

    public MigBug() {
        JPanel content = new JPanel();
        content.setLayout(new MigLayout("filly, debug", "[][grow][][grow]"));

        content.add(new JLabel("Label 1"));
        content.add(new JComboBox());

        content.add(new JLabel("Label 2"));
        content.add(new JTextField(25), "growx, wrap");

        content.add(new JLabel("BIG"), "span, w :400:, h :200:, grow");

        setContentPane(content);
    }
}
