How to lose focus with JMenuItem or close JPopupMenu

The following example generates a popup menu.

The popup menu contains 2 items.

One is a JLabel and the other is a JTextField.

When either item is clicked, a simple statement is printed.

When the JLabel menu item is clicked, the popup menu goes away.
When the JButton menu item is clicked, the popup menu remains.

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenuItem;
import javax.swing.JPopupMenu;
import javax.swing.JToggleButton;



public class JPopupExample1
public static void main(String argv) throws Exception

final JPopupMenu menu = new JPopupMenu();
JFrame frame = new JFrame("PopupSample Example");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JMenuItem item = new JMenuItem("Item Label");
item.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
System.out.println("Label Pressed"); );

menu.add(item);

JToggleButton jTbutton = new JToggleButton("Click Me");
jTbutton.setToolTipText("Test Buttons");
jTbutton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
System.out.println("Button Pressed"); );

menu.add(jTbutton);

frame.setLayout(null);
JLabel label = new JLabel("Right Click here for popup menu");
label.setLocation(10, 10);
label.setSize(250, 50);
frame.add(label);
label.setComponentPopupMenu(menu);
frame.setSize(350, 250);
frame.setVisible(true);




Is there a simple way to lose focus (without sending it to another Component) after clicking the JButton so the Popup menu goes away?

You could call menu.setVisible(false); after System.out.println("Button Pressed"); in the Action Listener. e.g:

menu.setVisible(false);

System.out.println("Button Pressed");

JToggleButton jTbutton = new JToggleButton("Click Me");
jTbutton.setToolTipText("Test Buttons");
jTbutton.addActionListener(new ActionListener()
public void actionPerformed(ActionEvent e)
System.out.println("Button Pressed");
menu.setVisible(false);

);
