Detecting when user presses enter in Java

Question

I have a subclass of JComboBox. I attempt to add a key listener with the following code.

        addKeyListener(new KeyAdapter() 
        {
            pub         


        

Answer 1

This is NOT the proper approach. The editor for a JComboBox is a JTextField. If you want to handle the Enter key then you add an ActionListener to the text field.

Always avoid using KeyListeners.

Edit:

comboBox.getEditorComponent().addActionListener( ... );
