请教怎样给JTable加上横向滚动条

Answer 1

// TableFeature.java
// A test of the JTable class using default table models and a convenience
// constructor. Resizing and selection defaults are altered.
//
import java.awt.*;
import javax.swing.*;
import java.util.Date;
import java.io.File;
public class TableFeature extends JFrame {
String titles[] = new String[] {
"Directory?", "File Name", "Read?", "Write?", "Size", "Last Modified"
};
public TableFeature() {
super("Simple JTable Test");
setSize(300, 200);
setDefaultCloseOperation(EXIT_ON_CLOSE);
File pwd = new File(".");
Object[][] stats = getFileStats(pwd);
JTable jt = new JTable(stats, titles);
jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
jt.setColumnSelectionAllowed(true);
JScrollPane jsp = new JScrollPane(jt);
getContentPane().add(jsp, BorderLayout.CENTER);
}
public Object[][] getFileStats(File dir) {
String files[] = dir.list();
Object[][] results = new Object[files.length][titles.length];
for (int i=0; i < files.length; i++) {
File tmp = new File(files[i]);
results[i][0] = new Boolean(tmp.isDirectory());
results[i][1] = tmp.getName();
results[i][2] = new Boolean(tmp.canRead());
results[i][3] = new Boolean(tmp.canWrite());
results[i][4] = new Long(tmp.length());
results[i][5] = new Date(tmp.lastModified());
}
return results;
}
public static void main(String args[]) {
TableFeature tf = new TableFeature();
tf.setVisible(true);
}
}
关键代码:jt.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
