java运行的计算器的界面字体显示太小，要添加什么代码可以放大字体，并且拉大边框时字体也随之放大

如果是swing的话

JLabel jl = new JLabel("标签");

jl.setBounds(10, 10, 10, 10);这是控制标签位置；

控制文本的位置，你可以通过在“”里边加空格控制

jl.setFont(new Font("宋体", Font.BOLD, 20));

这是控制文本字体，那个20就是大小选择，可以改变的

一个java初级的界面问题（已有代码，帮忙添加几行就可以）——字体对话框

我在你的基础上稍微添加了一些代码，现在可以改变字体大小了：

import java.awt.event.*;

import javax.swing.*;

import java.awt.*;

class FontDialog extends JDialog implements ItemListener, ActionListener {

JComboBox list;

JComboBox listSize; //显示可以选择的字体大小

JTextArea text;

Font font;

JButton yes, cancel;

JComponent com;

FontDialog(JComponent com) {

this.com = com;

setModal(true);

yes = new JButton("Yes");

cancel = new JButton("cancel");

yes.addActionListener(this);

cancel.addActionListener(this);

text = new JTextArea(2, 25);

list = new JComboBox();

listSize = new JComboBox();

GraphicsEnvironment ge = GraphicsEnvironment

.getLocalGraphicsEnvironment();

String fontName[] = ge.getAvailableFontFamilyNames();

for (int i = 0; i fontName.length; i++){

list.addItem(fontName[i]);

}

//定义字体大小数组,字体大小可以自行定义

int[] fontSize = new int[20];

for (int i = 0; i fontSize.length; i++){

fontSize[i] = i+5;

listSize.addItem(fontSize[i]);

}

list.addItemListener(this);

listSize.addItemListener(this); //为设置字体大小的添加监听器

Container con = getContentPane();

con.setLayout(new FlowLayout());

Box boxH1 = Box.createHorizontalBox(), boxH2 = Box

.createHorizontalBox(), boxH3 = Box.createHorizontalBox();

Box boxBase = Box.createVerticalBox();

boxH1.add(list);

boxH1.add(listSize); //添加字体大小设置到面板中

boxH2.add(text);

boxH3.add(yes);

boxH3.add(cancel);

boxBase.add(boxH1);

boxBase.add(boxH2);

boxBase.add(boxH3);

con.add(boxBase);

setBounds(100, 100, 280, 170);

setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);

validate();

}

public void itemStateChanged(ItemEvent e) {

String name = (String) list.getSelectedItem();

Integer size = (Integer) listSize.getSelectedItem(); //获得设置的字体大小

font = new Font(name, Font.PLAIN, size);

text.setFont(font);

text.setText("hello,奥运");

}

public void actionPerformed(ActionEvent e) {

if (e.getSource() == yes) {

com.setFont(font);

setVisible(false);

} else if (e.getSource() == cancel) {

setVisible(false);

}

}

}

class Dwindow extends JFrame implements ActionListener {

JTextArea text;

JToolBar bar;

Container con;

JButton buttonFont;

Dwindow() {

buttonFont = new JButton("设置字体");

text = new JTextArea("显示内容");

buttonFont.addActionListener(this);

bar = new JToolBar();

bar.add(buttonFont);

con = getContentPane();

con.add(bar, BorderLayout.NORTH);

con.add(new JScrollPane(text));

setBounds(60, 60, 300, 300);

setVisible(true);

validate();

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

}

public void actionPerformed(ActionEvent e) {

if (e.getSource() == buttonFont) {

FontDialog dialog = new FontDialog(text);

dialog.setVisible(true);

}

}

}

public class DialogExample {

public static void main(String args[]) {

new Dwindow();

}

}
