ねえ、パネル内のすべてのパネルを大きなパネルの左側に揃えようとしています。
ここに私が現在直面しているものの写真があります：
マスター パネル (他のすべてのパネルを含むパネル - 私はそれをマスターと呼びます!) の場合、作成時に次のコードを使用しています。
JPanel panel = new JPanel();
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
その中のパネルごとに BoxLayout も使用していますが、各パネルで [jpanel].setAlignmentX(Component.LEFT_ALIGNMENT) などを試しましたが、うまくいかないようです。
どんな助けでも大歓迎です！
:)
編集:「ボックスの寸法(m):」ラベルについて、それが含まれているパネルの上部に揃える方法はありますか? それはそれ自身のパネルにあります。
編集：修正後：
以下の解決策、あなたの助けに感謝します:)
すべてのニーズに応じて、多くの可能性があります。
ここで行ったのは、複合パネルを使用GridBagLayoutし、レイアウトを調整するために使用したことだけです

MigLayoutを使用できます。
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);
}
});
}
}
