JAVA：当选择了jTextField时，在“ enter”按键上激活jFrameButton

Question

I have a program with a JFrame GUI and I want a button to be clicked when the user hits the Enter key from within a JTextField . Yes I have tried

rootPane.setDefaultButton(jButton5);

but it only works when the text field isn't selected. How could I have it click the button when the text field is selected?

Thank you in advance :D

Answer 1

JTextField.addActionListener(new ActionListener(){

            public void actionPerformed(ActionEvent e){

                    jButton5.doClick();

            }});

JTextField is you text field component. Then when you click the enter key, doClick method of JButton is invoked which Programmatically perform a "click". This does the same thing as if the user had pressed and released the button.

Answer 2

You'll have to add actionListener to textField and override method actionPerformed()

text.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        System.out.println("Text=" + text.getText());
        //Your logic
      }
});
