呵呵,好人做到底吧,这儿有个JTextPane的使用示例:
ps:代码不是偶写的,从网上copy过来滴.
import java.awt.*;
import javax.swing.*;
import javax.swing.text.*;
public class JTextPaneTest extends JFrame
{
private static final long serialVersionUID = 1L;
// main function
public static void main(String args[])
{
JTextPaneTest test = new JTextPaneTest();
test.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
test.setVisible(true);
}
public JTextPaneTest()
{
// Initialization
StyledDocument styledDoc = new DefaultStyledDocument();
JTextPane textPane = new JTextPane(styledDoc);
JScrollPane scrollPane = new JScrollPane(textPane);
// Get Available Font Family Name
String [] fontNames = GraphicsEnvironment.getLocalGraphicsEnvironment().getAvailableFontFamilyNames();
// Content
createStyle(\"Style01\",styledDoc,15,0,1,0,Color.RED,\"宋体\");
createStyle(\"Style02\",styledDoc,35,1,1,1,Color.GREEN,\"华文琥珀\");
createStyle(\"Style03\",styledDoc,25,1,0,0,Color.BLUE,\"隶书\");
createStyle(\"Style04\",styledDoc,18,1,0,0,new Color(0,128,128),fontNames[0]);
createStyle(\"Style05\",styledDoc,20,0,1,0,new Color(128,128,0),fontNames[7]);
createStyle(\"Style06\",styledDoc,22,1,0,1,new Color(128,0,128),fontNames[16]);
createStyle(\"Style07\",styledDoc,18,1,1,0,Color.RED,\"华文彩云\");
insertDoc(styledDoc,\"Size=18,Italic,red,font=宋体\n\",\"Style01\");
insertDoc(styledDoc,\"其实Java比C++简单多了\n\",\"Style02\");
insertDoc(styledDoc,\"Java中的MVC机制很好\n\",\"Style03\");
insertDoc(styledDoc,\"其实Java比C++简单多了\n\",\"Style07\");
insertDoc(styledDoc,\"Java is very good\n\",\"Style04\");
insertDoc(styledDoc,\"Java is very good\n\",\"Style05\");
insertDoc(styledDoc,\"Java is very good\n\",\"Style06\");
// Layout
this.getContentPane().setLayout(new BorderLayout());
this.getContentPane().add(scrollPane,BorderLayout.CENTER);
this.setSize(new Dimension(500,400));
this.setTitle(\"JTextPane Test!\");
this.setLocation(new Point(200,200));
}
public void insertDoc(StyledDocument styledDoc, String content,String currentStyle)
{

} catch (BadLocationException e) {
System.err.println(\"BadLocationException: \" + e);
}
}
public void createStyle(String style,StyledDocument doc,int size,int bold,int italic,int underline,Color color,String fontName)
{
Style sys = StyleContext.getDefaultStyleContext().getStyle(StyleContext.DEFAULT_STYLE);
try { doc.removeStyle(style); } catch(Exception e) {} //先删除这种Style,假使他存在
Style s = doc.addStyle(style,sys); // 加入
StyleConstants.setFontSize(s,size); // 大小
StyleConstants.setBold(s,(bold==1)?true:false); // 粗体
StyleConstants.setItalic(s,(italic==1)?true:false); // 斜体
StyleConstants.setUnderline(s,(underline==1)?true:false); // 下划线

}
