The following Demo.java demonstrates the usage of JFileChooser.
Demo.java
import java.awt.EventQueue;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JTextField;
import javax.swing.JButton;
public class Demo {
private JFrame frame;
private JTextField txtPath;
/**
* Launch the application.
*/
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
try {
Demo window = new Demo();
window.frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
}
}
});
}
/**
* Create the application.
*/
public Demo() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setLayout(null);
txtPath = new JTextField();
txtPath.setBounds(10, 10, 414, 21);
frame.getContentPane().add(txtPath);
txtPath.setColumns(10);
JButton btnBrowse = new JButton("Browse");
btnBrowse.setBounds(10, 41, 87, 23);
frame.getContentPane().add(btnBrowse);
btnBrowse.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFileChooser fileChooser = new JFileChooser();
// For Directory
fileChooser.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
// For File
//fileChooser.setFileSelectionMode(JFileChooser.FILES_ONLY);
fileChooser.setAcceptAllFileFilterUsed(false);
int rVal = fileChooser.showOpenDialog(null);
if (rVal == JFileChooser.APPROVE_OPTION) {
txtPath.setText(fileChooser.getSelectedFile().toString());
}
}
});
}
}
Please note that if u can configure the FileSelectionMode to JFileChooser.FILES_ONLY if you want to browse file.
Done =)
