GridBagLayout - 不同的行大小

Question

通常情况下，我对Swing和不同的布局并没有那么糟糕，但是这个真的让我烦恼。

使用GridBagLayout在下面的图表上出了什么问题？每个厚矩形都是JPanel。 细线只是正确y值的帮助。

提前致谢！

package at;

import java.awt.Color;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;

public class GridMask extends JFrame {

JPanel jPanel1, jPanel2, jPanel3, jPanel4, jPanel5, jPanel6;

public GridMask() {
    unimportantStuff();

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

    GridBagConstraints gbc;

    gbc = getGbc(0, 0, 3, 1, 0.5);
    gbl.setConstraints(jPanel1, gbc);

    gbc = getGbc(1, 0, 4, 1, 0.75);
    gbl.setConstraints(jPanel2, gbc);

    gbc = getGbc(2, 0, 3, 1, 0.5);
    gbl.setConstraints(jPanel3, gbc);

    gbc = getGbc(0, 3, 3, 1, 0.5);
    gbl.setConstraints(jPanel4, gbc);

    gbc = getGbc(1, 4, 2, 1, 0.25);
    gbl.setConstraints(jPanel5, gbc);

    gbc = getGbc(2, 3, 3, 1, 0.5);
    gbl.setConstraints(jPanel6, gbc);

    add(jPanel1);
    add(jPanel2);
    add(jPanel3);
    add(jPanel4);
    add(jPanel5);
    add(jPanel6);

    setVisible(true);
}

private GridBagConstraints getGbc(int x, int y, int height, int width, double weightY) {
    GridBagConstraints gbc = new GridBagConstraints();
    gbc.gridx = x;
    gbc.gridy = y;
    gbc.gridheight = height;
    gbc.gridwidth = width;
    gbc.fill = GridBagConstraints.BOTH;
    gbc.weightx = 1.0;
    gbc.weighty = weightY;

    return gbc;
}

private void unimportantStuff() {
    jPanel1 = new javax.swing.JPanel();
    jPanel2 = new javax.swing.JPanel();
    jPanel3 = new javax.swing.JPanel();
    jPanel4 = new javax.swing.JPanel();
    jPanel5 = new javax.swing.JPanel();
    jPanel6 = new javax.swing.JPanel();

    jPanel1.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    jPanel2.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    jPanel3.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    jPanel4.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    jPanel5.setBorder(BorderFactory.createLineBorder(Color.BLACK));
    jPanel6.setBorder(BorderFactory.createLineBorder(Color.BLACK));
}

public static void main(String[] args) {
    new GridMask();
}
}

结果是一个JFrame，其中两行具有不同的高度，但一行中的单元格具有相同的高度。

但连续的单元格具有相同的高度。

gbc.fill = GridBagConstraints.BOTH;

您告诉布局调整所有组件的大小以填充每个单元格中的可用空间。
