Java Swing（BoxLayout）对齐问题 [英] Java Swing (BoxLayout) alignment issues

问题描述

对于Java Swing来说，我是一个非常陌生的人，在布局合理的过程中我遇到了很多问题。我已经在该网站上签出了google甚至其他答案，但是我发现没有任何信息似乎可以解决该问题。这是我努力的结果：

I am extremely new to Java Swing, and I'm having quite a bit of issues getting a nice layout going. I have checked out google, and even other answers on this website, but no information I find seems to solve the issue. Here is the result of my efforts:

如您所见，标签，文本字段和按钮都未对齐。我的目标是所有人都具有相同的左边框，按钮和文本字段具有相同的右边框，这些左，右边框与左，右边框的距离均相同

As you can see, the label, text field, and button are all out of alignment. It is my goal for all of them to have the same left-hand border, and for the button and text field to have the same right-hand border, with these left and right hand borders being each the same distance from the left and righthand sides of my window.

这是我代码的重要部分：

Here are the important parts of my code:

    public void run()
    {
         JFrame frame = new JFrame("Arduino Server");
         frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
         InstancePanel = new ServerGUIPanel();
         frame.getContentPane().add(InstancePanel);
         frame.pack();
         frame.setVisible(true);
    }

然后在ServerGUIPanel.java中：

And, in ServerGUIPanel.java:

    public ServerGUIPanel()
    {
        setLayout(new BoxLayout(this, BoxLayout.Y_AXIS));
        setPreferredSize(new Dimension(500, 500));
        setBorder(new EmptyBorder(10, 10, 10, 10));



        StatusLabel = new JLabel("STATUS: BOOTUP");
        add(StatusLabel);

        PortField = new JTextField();
        PortField.setPreferredSize(new Dimension(5000, 20));
        PortField.setMaximumSize(PortField.getPreferredSize());
        PortField.setActionCommand("PortChanged");
        add(PortField);

        ConnectionButton = new JButton();
        ConnectionButton.setPreferredSize(new Dimension(5000, 20));
        ConnectionButton.setMaximumSize(ConnectionButton.getPreferredSize());
        ConnectionButton.setActionCommand("ConnectionClicked");
        add(ConnectionButton);
    }

有人对此有一个简单的解决方案吗？我在这里做什么错了？

Does anyone have a simple solution to this? What am I doing wrong here?

非常感谢！

推荐答案

阅读如何使用BoxLayout 作为使用BoxLayout的基础知识以及有关对齐问题的部分。

Read the section from the Swing tutorial on How to Use BoxLayout for the basics of using a BoxLayout as well as a section on alignment issues.

基本上，您需要确保所有组件的alignmentX值都设置为左对齐。

Basically you need to make sure the alignmentX value of all components is set to be left aligned.

也：

1. 不要使用setPreferredSize（）设置组件的大小。每个Swing组件将确定其自己的首选大小。


2. 使用Java命名约定。变量名称不应以大写字母开头。
