java 设置字体格式_教程

Java Swing中可以给每个控件设置字体格式和其他属性的设置，示例如下：

submit= new JButton("登陆")

submit.setFont(new Font("宋体", Font.PLAIN, 16))

三个参数分别表示：字体，样式（粗体，斜体等），字号

submit.setForeground(Color.RED)

这个表示给组件上的文字设置颜色Color.RED表示红色

当然你也可以自己给RGB的值比如 submit.setForeground(new Color(215,215,200))

java中没有自带的字体对话框，这需要自己来编写。

text.setFond("字体名字"，字形（如，fond.bold）,大小)

import java.awt.*

import java.awt.event.*

import javax.swing.JColorChooser

//import javax.swing.border.*

class ff extends Frame implements ActionListener

{

Choice font,size,bolder

Button bb

ff(String s)

{

setTitle(s)

font=new Choice()

bolder=new Choice()

size=new Choice()

//bolder.add加监视器

//font.add加监视器

//size.add加监视器

Panel p1=new Panel()

Panel p2=new Panel()

bb=new Button("点击打开")

bb.addActionListener(this)

p1.setLayout(new GridLayout(4,1))

p2.setLayout(new GridLayout(4,1))

GraphicsEnvironment gg=GraphicsEnvironment.getLocalGraphicsEnvironment()

String ss[]=gg.getAvailableFontFamilyNames()

String bold[]={"Font.BOLD","Font.CENTER_BASELINE","Font.CENTER_BASELINE","Font.ITALIC",

"Font.PLAIN","Font.ROMAN_BASELINE","Font.TRUETYPE_FONT"}

for(int i=126i<ss.lengthi++)

font.add(ss[i])

for(int i=12i<=64i+=2)

{

String w=String.valueOf(i)

size.add(w)

}

for(int i=0i<bold.lengthi++)

{

bolder.add(bold[i])

}

p1.add(new Label("请选择字体"))

p1.add(font)

p1.add(new Label("请选择大小"))

p1.add(size)

p2.add(new Label("请选择字型"))

p2.add(bolder)

p2.add(new Label("请选择字体颜色"))

p2.add(bb)

add(p2,BorderLayout.WEST)

add(p1,BorderLayout.EAST)

setSize(250,150)

setVisible(true)

pack()

addWindowListener(new WindowAdapter()

{

public void windowClosing(WindowEvent ee)

{

System.exit(0)

}

})

}

public void actionPerformed(ActionEvent e)

{

Color cc=JColorChooser.showDialog(this,"颜色对话框",null)

bb.setBackground(cc)//应用举例

}

public class font

{

public static void main(String[] args)

{

new ff("字体对话框")

}

这是我自己改的，你可以参考，我用的是simsun，你只需要修改最后一行，把路径指向simsun.ttf所在的路径就可以了，注意需要有fonts.scale和fonts.dir。
