texteditorclass.java

这是我编的一个文本编辑器

import javax.swing.*;
import java.awt.*;
import javax.swing.UIManager;
public class TextEditorclass
{
	public static void main(String[] args)
	{
		try
		{
			UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName());
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		TextEditor editor=new TextEditor();
		editor.setSize(800,600);
		Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        Dimension frameSize = editor.getSize();
        if (frameSize.height > screenSize.height) 
        {
           frameSize.height = screenSize.height;
        }
        if (frameSize.width > screenSize.width)
        {
           frameSize.width = screenSize.width;
        }
        editor.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height 
                            - frameSize.height) / 2);
		editor.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		editor.setVisible(true);	
	}
}
