In my method bellow, the JTextArea will be displayed when i click on the button helpBut. After displaying the help text (the text written in JTextArea : helpText), i would like to close this text by pressing on the escape key. I tried to use the method addKeyListener (bellow), but it has not worked.
public void clickButton (JButton helpBut, JTextArea helpText)
helpBut.addMouseListener(new MouseAdapter()
@Override
public void mouseClicked(MouseEvent e)
JPopupMenu helpPopup = new JPopupMenu();
helpPopup.add(helpText);
if (!helpPopup.isVisible())
helpPopup.show(helpBut,20,20);
else
helpPopup.setVisible(false);
);
helpText.addKeyListener(new KeyAdapter()
@Override
public void keyPressed(KeyEvent e)
if(helpText.isVisible())
if(e.getKeyCode() == KeyEvent.VK_ESCAPE)
helpText.setVisible(false);
);
I figured out that the compiler calls the method addKeyListener only if i click on the JtextArea.

1. Don't use a MouseListener to listen for a button click. Instead the API is designed for you to use anActionListener. 2) The escape key should be the default key to close the popup. At least is works by default for me. Post your Minimal, Complete, and Verifiable example that demonstrates the problem.

@camickr why dont use MouseListener for a button click ? Do you mean using mousePressed is better ? I have one JPanel that content of the help button (helpBut), i click on this button and after that, i press on the JTextArea, both JPanel and JText will be closed in the same time, i would like to close JTextArea first, that is reason why i use addKeyListener in this method buttonClick.

Read the section from the Swing tutorial on [How to Use Buttons]() for more information and working examples. Your explanation of the problem still makes no sense to me.
