更改菜单栏和菜单项的字体 [英] Change menu bar and menu items font

问题描述

我正在尝试使菜单栏项目和项目的项目越来越小，我已经在这里找到了一些（所以不要把这个标记为重复请），而且我没有任何帖子发现工作。

我已经尝试了下面的代码没有成功：

  Font f = new Font（sans-serif，Font.PLAIN，12）; 
 UIManager.put（menuBar.font，f）; 
  

和

 <$ c）c> menuBar.setFont（new Font（menuBar.getFont（）。getFontName（），menuBar.getFont（）。getStyle（），12））; 
  

这是我在编辑字体的代码：

  private class foo {
 private JMenu mnArchivo; 
私人JMenuBar menuBar; 
 menuBar = new JMenuBar（）; 
 frmAdministracinHospital.setJMenuBar（menuBar）; 
 
 JRadioButtonMenuItem rdbtnmntmGrande = new JRadioButtonMenuItem（Grande）; 
 rdbtnmntmGrande.addActionListener（new MiGrandeActionListener（））; 
 rdbtnmntmGrande.setIcon（new ImageIcon（PrincipalWindow.class.getResource（/ presentacion / fontbig.png）））; 
 buttonGroup.add（rdbtnmntmGrande）; 
 mnTamanoFuente.add（rdbtnmntmGrande）; 
 
 private class MiGrandeActionListener implements ActionListener {
 public void actionPerformed（ActionEvent e）{
 
 Font f = new Font（menuBar.getFont（）。getFontName（）， menuBar.getFont（）。getStyle（），12）; 
 UIManager.put（Menu.font，f）; 
 
 
 
 
 
 
 
 
 
解决方案
这是因为 
 
 
 
更改字体后： 
 
 
 ，下一次，请贴出一个有效的，与我一样，所以我们可以复制粘贴，我没有使用 actionListener ，因为问题与动作无关，而是字体。或图标因为它不相关，我做了一个完整的示例代码，你可以复制粘贴，看看它是如何工作的，而不需要修改任何东西，这就是你所要求的。  
 
 
对于 MenuBar 字体，您需要调用： 
 
 
  UIManager.put（Menu.font，f）; 
  
对于 MenuItem  
  UIManager.put（MenuItem.font，f）; 
  
 
I'm trying to make the menu bar items and the items of the items bigger and smaller, I've seached here a bit before (so don't mark this as repeated please) and none of the posts I've found are working.


I've tried the following codes without success:
Font f = new Font("sans-serif", Font.PLAIN, 12);
UIManager.put("menuBar.font", f);
And
menuBar.setFont(new Font(menuBar.getFont().getFontName(), menuBar.getFont().getStyle(), 12));
And this is my code where I'm trying to edit the font:
private class foo{
        private JMenu mnArchivo;
        private JMenuBar menuBar;
        menuBar = new JMenuBar();
        frmAdministracinHospital.setJMenuBar(menuBar);

    JRadioButtonMenuItem rdbtnmntmGrande = new JRadioButtonMenuItem("Grande");
            rdbtnmntmGrande.addActionListener(new MiGrandeActionListener());
            rdbtnmntmGrande.setIcon(new ImageIcon(PrincipalWindow.class.getResource("/presentacion/fontbig.png")));
            buttonGroup.add(rdbtnmntmGrande);
            mnTamanoFuente.add(rdbtnmntmGrande);

    private class MiGrandeActionListener implements ActionListener {
            public void actionPerformed(ActionEvent e) {

                Font f = new Font(menuBar.getFont().getFontName(), menuBar.getFont().getStyle(), 12);
                UIManager.put("Menu.font", f);
            }
        }
Any clue please?
解决方案
That's because there's not "menuBar.font" key in the UIManager class, it should be:
UIManager.put("MenuBar.font", f);
i.e. Caps are important or:
UIManager.put("MenuItem.font", f);
for each JMenuItem's font

Here's a list of these properties

EDIT: Added mcve

I don't see where it's not working, if I run this code, it works fine for me
import java.awt.Font;

import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenu;
import javax.swing.JMenuBar;
import javax.swing.JMenuItem;
import javax.swing.SwingUtilities;
import javax.swing.UIManager;

public class UIManagerFontChangeExample {

    private JFrame frame;
    private JLabel label;
    private JMenuItem item1, item2;
    private JMenu menu;
    private JMenuBar bar;

    public static void main(String[] args) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                Font f = new Font("sans-serif", Font.PLAIN, 12);
                UIManager.put("Menu.font", f);
                UIManager.put("MenuItem.font", f);
                UIManagerFontChangeExample example = new UIManagerFontChangeExample();
                example.createAndShowGui();
            }
        });
    }

    public void createAndShowGui() {
        frame = new JFrame("Font changing example");
        label = new JLabel("This is a label");
        bar = new JMenuBar();
        menu = new JMenu("Menu");
        item1 = new JMenuItem("Item1");
        item2 = new JMenuItem("Item2");

        menu.add(item1);
        menu.add(item2);
        bar.add(menu);

        frame.add(label);
        frame.setJMenuBar(bar);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }
}
Before changing font:



After changing font:



The code I added above is called: Minimal, Complete and Verifiable Example, next time, please post a valid one, the same I did, so we can copy-paste, I didn't use an actionListener because the question isn't related to the actions, but the font. Or Icon because it's not related either, I did a full example code that you can copy-paste and see how it works, without modifying anything, that's what you were asked for.

For the MenuBar font you need to call:
UIManager.put("Menu.font", f);
And for the MenuItem
UIManager.put("MenuItem.font", f);
