[[swing 的几种布局]]

GUI设计器

使用GUI设计器生成界面

GUI设计器可将GUI生成到二进制类文件或Java源代码

Swing form文件

有时界面不好调整,可直接修改form文件

Swing与多线程

更改JOption的背景颜色以及button的字体

https://blog.csdn.net/Mr_Pang/article/details/47339373

具体的可以更改的东西，请看点击打开链接

UIManager.setLookAndFeel(getLookAndFeel());
UIManager.put("OptionPane.background",Color.WHITE);
UIManager.put("Panel.background", Color.WHITE);
UIManager.put("Panel.foreground", Color.black);
UIManager.put("Button.background", Color.WHITE);
UIManager.put("Button.foreground", Color.black);

控件设置焦点

//先setVisible(true);显示窗口
//passwordField1.dispatchEvent(new FocusEvent(passwordField1,FocusEvent.FOCUS_GAINED,true));
passwordField1.requestFocusInWindow();

passwordField1.requestFocus();

passwordField1.enableInputMethods(true);//开启输入法支持

//放到windowOpened中
frame.addWindowListener(new WindowListener() 
            @Override
            public void windowOpened(WindowEvent e) 
                passwordField1.requestFocusInWindow();
                passwordField1.enableInputMethods(true);
            
        );

JTextField内容修改

class TextDocumentListener implements DocumentListener

        @Override
        public void insertUpdate(DocumentEvent e) 
            GetCaptcha();
        

        @Override
        public void removeUpdate(DocumentEvent e) 
            GetCaptcha();
        

        @Override
        public void changedUpdate(DocumentEvent e) 
        
    
DocumentListener documentListener = new TextDocumentListener();
textFieldServer.getDocument().addDocumentListener(documentListener);

程序配置文件

package com.founder.MediaxFileTool;

import java.io.*;
import java.util.Properties;

public class ConfigManager 
    private static ConfigManager configManager;
    private static Properties properties;
    private static String strConfigFile;
    public ConfigManager() 

        String mediaxFileToolpath = System.getProperty("user.home") + File.separator + ".xx";

        File mediaxFileToolDir = new File(mediaxFileToolpath);
        if (!mediaxFileToolDir.exists()) 
            mediaxFileToolDir.mkdirs();
        

        strConfigFile = mediaxFileToolpath + File.separator + "xx.xml";

        File configFile = new File(strConfigFile);

        properties = new Properties();

        if (configFile.exists())

            try 
                InputStream input=new BufferedInputStream(new FileInputStream(strConfigFile));
                properties.loadFromXML(input);
             catch (IOException e) 
                e.printStackTrace();
                throw new RuntimeException(e);
            
        

    

    public static ConfigManager getInstance()
        if(configManager==null)
            configManager = new ConfigManager();
        
        return configManager;
    

    public String getString(String key)
        return properties.getProperty(key);
    
    public void setString(String key,String value)
        properties.setProperty(key,value);
    

    public void save() 
        try 
            OutputStream output = new FileOutputStream(strConfigFile);
            properties.storeToXML(output,"xx配置","utf-8");
         catch (IOException e) 
            throw new RuntimeException(e);
