嘿，我正在尝试将面板内的所有面板对齐到较大面板的左侧。
这是我目前面临的图片：
对于主面板（包含所有其他面板的面板 - 我将其称为主面板！）我在创建它时使用以下代码：
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
对于其中的每个面板，我也在使用 BoxLayout，但我已经在每个面板上尝试了 [jpanel].setAlignmentX(Component.LEFT_ALIGNMENT) 之类的东西，但这似乎不起作用。
任何帮助，将不胜感激！
:)
编辑：对于“框（m）的尺寸：”标签，有没有办法将它与它所在的面板顶部对齐？它在自己的面板中。
编辑：一旦固定：
下面的解决方案，谢谢大家的帮助:)
您有多种可能性，具体取决于您的所有需求。
我在这里所做的只是使用复合面板并GridBagLayout用于调整布局
public class BadLayout03 {
public static void main(String[] args) {
new BadLayout03();

public BadLayout03() {

您可以使用MigLayout：
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
import net.miginfocom.swing.MigLayout;
public class PanelAlignment extends JFrame {
JPanel contentPane = new JPanel();
JPanel firstPanel = new JPanel();
JPanel secondPanel = new JPanel();
JPanel thirdPanel = new JPanel();
JLabel dimOfBox, rein, seaTop;
public PanelAlignment() {
contentPane.setLayout(new MigLayout());
firstPanel.add(dimOfBox = new JLabel("Dimensions of box (m): "));
firstPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK));
contentPane.add(firstPanel,"wrap");
secondPanel.add(rein = new JLabel("Reinforcement: "));
secondPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK));
contentPane.add(secondPanel,"wrap");
thirdPanel.add(dimOfBox = new JLabel("Sealable top: "));
thirdPanel.setBorder(BorderFactory.createLineBorder(Color.BLACK));
contentPane.add(thirdPanel,"wrap");
add(contentPane);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
PanelAlignment pa = new PanelAlignment();
pa.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
pa.pack();
pa.setVisible(true);
}
});
}
}
你会得到这样的东西：
