Set default focus on JButton

I have a JButton and a JTextField on a JFrameFrom. I want to enter some data in text field and then when I press enter key, an event occurs without set focus on the button. some thing like Yahoo log-in page. You can enter username and password and without traversing the focus to the sign-in button, when press enter, sign-in will occur. How could I do this?

Solution

  • If I understood your question good, solution should be easy. Just add ActionListener on JTextField:

    textField.addActionListener(new ActionListener(){
    
    public void actionPerformed(ActionEvent e){
        //Do stuff...
    }

});

    When JTextField is focused and when you hit an Enter key, event will occur.
