如何将jPanel中的所有jPanel对齐到左边?

[英]How to align all jPanels within a jPanel to the left?

Hey I'm attempting to align all panels within a panel to the left of the larger panel. 嘿,我试图将面板内的所有面板对齐到较大面板的左侧。

here is a picture of what I'm currently faced with: 这是我目前面临的情况:

箱面板布局

For the master panel (the one that contains all other panels - I shall call it the master!) I'm using the following code when creating it: 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));

For each of the panels within it I'm also using the BoxLayout, but I've tried things like [jpanel].setAlignmentX(Component.LEFT_ALIGNMENT) on each panel but that doesn't seem to work. 对于其中的每个面板我也使用BoxLayout,但我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。

Any help would be appreciated! 任何帮助,将不胜感激!

:) :)

edit: for the "Dimensions of box(m):" label, is there any way of aligning that to the top of the panel it's contained in? 编辑:对于“盒子尺寸(m):”标签,有没有办法将它对齐到它所包含的面板顶部? It's in a panel of its own. 它在自己的一个小组中。

edit: Once fixed: 编辑:修复后:

JPanel问题一旦修复

Solution below, thanks all for your help :) 以下解决方案,谢谢大家的帮助:)

You have a number of possibilities, depending on you over all needs. 您有多种可能性,具体取决于您的所有需求。

All I've done here is used compound panels and using GridBagLayout to adjust the layouts 我在这里所做的只是使用复合面板并使用GridBagLayout来调整布局

You can use MigLayout : 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);
            }
        });
    }

}
