我們想知道如何在JTree中添加Windows目錄結(jié)構(gòu)。
import java.io.File;
import javax.swing.JFrame;
import javax.swing.JTree;
import javax.swing.tree.DefaultMutableTreeNode;
import javax.swing.tree.DefaultTreeModel;
public class Main extends JFrame {
public static void main(String[] args) {
new Main().setVisible(true);
}
private JTree tree;
public Main() {
this.tree = new JTree();
this.add(this.tree);
File fileRoot = new File("C:/");
DefaultMutableTreeNode root = new DefaultMutableTreeNode(fileRoot);
DefaultTreeModel model = new DefaultTreeModel(root);
File[] subItems = fileRoot.listFiles();
for (File file : subItems) {
root.add(new DefaultMutableTreeNode(file));
}
this.tree.setModel(model);
this.pack();
}
}
