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，但是这个真的让我很烦。

以下图表使用 GridBagLayout 有什么问题？每个厚矩形都是一个 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。

Answer 1

但一行中的单元格高度相同。

gbc.fill = GridBagConstraints.BOTH;

您是在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。
