我在互聯網上的stackoverflow &上搜索,但它沒有工作。滾動條不出現。請幫助我,如果它有效,我會很樂意爲您的答案投票。下面是代碼:(在此先感謝!)JScrollPane沒有出現在JTextPane上
package com.james.client;
import javax.swing.*;
import javax.swing.UIManager.LookAndFeelInfo;
public class Main extends JFrame{
private static final long serialVersionUID = 1L;
public static void main(String [] args) throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException
{
//Set program to nimbus
for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) {
if ("Nimbus".equals(info.getName())) {
UIManager.setLookAndFeel(info.getClassName());
break;
}
}
//Window stuff
JFrame window = new JFrame("MinecraftProgrammer++");
window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setSize(1000, 600);
window.setResizable(false);
JPanel content = new JPanel();
content.setLayout(null);
JMenuBar nav = new JMenuBar();
JMenu file = new JMenu("File");
JMenu newfile = new JMenu("New");
JMenuItem Class = new JMenuItem("Class");
JMenuItem Package = new JMenuItem("Package");
JMenuItem Other = new JMenuItem("Other");
newfile.add(Class);
newfile.add(Package);
newfile.add(Other);
file.add(newfile);
nav.add(file);
JTextPane code = new JTextPane();
JScrollPane codescroll = new JScrollPane(code);
codescroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
codescroll.setBounds(0, 0, 994, 547);
code.setAutoscrolls(true);
code.setBounds(0, 0, 994, 547);
content.add(codescroll);
content.add(code);
window.setJMenuBar(nav);
//No more code after this line
window.add(content);
window.setVisible(true);
}
}
完美的作品!我做了多麼糟糕的錯誤。謝謝。 – 2013-05-05 00:05:38
@JamesL。沒問題。在開始使用Swing時自己犯了很多錯誤。 – 2013-05-05 00:06:21
