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);
