java修改JFrame默認字體方式

java修改JFrame默認字體

修改默認字體的方法很簡單。首先我們隨便寫一個按鈕出來:

import javax.swing.*; 
public class Test{
       static final int WIDTH = 300;
       static final int HEIGHT = 200;
       public static void main(String[] args){
             JFrame jf = new JFrame();
             jf.setVisible(true);
             jf.setSize(WIDTH,HEIGHT);
             jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
             JPanel jp = new JPanel();
             jf.setcontentPane(jp);
             JButton jb = new JButton("確定");
             jp.add(jb);
             jf.pack();
       }
}

接著我們可以加上這麼一行:

UIManager.put("Button.font", new java.awt.Font("宋體", 0, 12));

開頭的import加上:

import javax.swing.UIManager;

這樣就可以改字體瞭。

字體類型和大小可以隨便改,隻要電腦裡有安裝就行瞭。“0”位置代表的是字體風格,一般不做修改。(如斜體、加粗等,要修改的話請自行查閱API……我也不太記得瞭。。)

不建議使用網上的個性字體,因為這樣做出來的軟件程序到別的電腦上用會產生字體方面的問題。而且盡量少用生僻字,以免某些字體庫裡沒有收錄對應的字形。

自定義的字體可以進行一下封裝:(下面的部分摘自網絡)

public class FontClass {
 public static void loadIndyFont() {
  UIManager.put("CheckBox.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Tree.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Viewport.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ProgressBar.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("RadioButtonMenuItem.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("FormattedTextField.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ToolBar.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ColorChooser.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ToggleButton.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Panel.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TextArea.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Menu.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("RadioButtonMenuItem.acceleratorFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Spinner.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Menu.acceleratorFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("CheckBoxMenuItem.acceleratorFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TableHeader.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TextField.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("OptionPane.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("MenuBar.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Button.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Label.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("PasswordField.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("InternalFrame.titleFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("OptionPane.buttonFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ScrollPane.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("MenuItem.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ToolTip.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("List.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("OptionPane.messageFont", new java.awt.Font("宋體", 0, 12));
  UIManager.put("EditorPane.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("Table.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TabbedPane.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("RadioButton.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("CheckBoxMenuItem.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TextPane.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("PopupMenu.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("TitledBorder.font", new java.awt.Font("宋體", 0, 12));
  UIManager.put("ComboBox.font", new java.awt.Font("宋體", 0, 12));
 }

然後我們隻需要在我們想要使用的時候,加上一句:

FontClass.loadIndyFont();

就行瞭~

JFrame基本參數設置

import java.io.IOException;
import java.awt.Font;
import java.awt.event.WindowEvent;
import java.awt.event.WindowListener;
import javax.swing.JFrame;
import javax.swing.ImageIcon;
import javax.swing.UIManager;
import javax.imageio.ImageIO;
public class Frame implements WindowListener {
    public static JFrame frame;
    public Frame() {
        initialize();
    }
    
    private void initialize(){
        // 新建窗體
        frame = new JFrame();
        // 設置窗體自動調節大小
        frame.pack();
        // 設置窗體位置、大小
        frame.setBounds(100, 100, 100, 100);
        // 設置窗體是否可調節大小
        frame.setResizable(false);
        // 設置窗體佈局
        frame.getContentPane().setLayout(null);
        // 設置窗體標題
        frame.setTitle("Frame");
        // 設置窗體字體
        frame.setFont(new Font("黑體", Font.PLAIN, 17));
        // 設置窗體在屏幕中央打開
        frame.setLocationRelativeTo(null);
        // 設置窗體默認關閉方式為退出程序
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        // 設置窗體圖標
frame.setIconImage(ImageIO.read(this.getClass().getResource("/priv/image/image.png")));
        // 設置窗體觀感(皮膚/主題)
    UIManager.setLookAndFeel("com.sun.java.swing.plaf.windows.WindowsLookAndFeel");
        // 設置窗體是否可見
        frame.setVisible(true);
        // 添加 WindowListener
        frame.addWindowListener(this);
    }
    
    /**
     * @description 重寫 WindowListener
     * @param e
     */
    public void windowClosing(WindowEvent e) {
    }
    public void windowClosed(WindowEvent e) {
    }
    public void windowOpened(WindowEvent e) {
    }
    public void windowIconified(WindowEvent e) {
    }
    public void windowDeiconified(WindowEvent e) {
    }
    public void windowActivated(WindowEvent e) {
    }
    public void windowDeactivated(WindowEvent e) {
    }
    
    public static void main(String args[]) {
        new Frame();
    }
}

以上為個人經驗,希望能給大傢一個參考,也希望大傢多多支持WalkonNet。
