Setting focus on JOptionPane text field

Hi. I have created a custom text field that I am using in a JOptionPane. When I run the program, the JOptionPane comes up and looks great, however the focus always goes to the first button. I want the focus to start on the text field. I've tried requestFocus(), but this doesn't seem to work. Is there something special that I need to do to get the focus on the text field. See my code below:


Thanks for any help!!

Don't know.

Went through the JOptionPane page in the API, and the tutorial link on it, and I wasn't convinced there was anything dircetly useful.

Look at this thread. Michael Dunn explained how to go through all the components of a JFrame and remove the close minimise and maximise buttons.

Suggest you try
  • Instantiate your Dialog (as in the tutorial link).
  • Go through all its components,
  • Find the component you wish to have focus,
  • Call its requestFocus method, and finish your search.
  • See whether that works.

    Hi Jennifer,

    I had the same problem. You don't need the requestFocusInWindow() method.
    Instead, try with JOptionPane.showOptionDialog instead of JOptionPane.showConfirmDialog. The method I suggest, has a last parameter initialValue. If you have a JTextField and you give a String to this last parameter, JOptionPane will initialize the JTextField with that string and it will have the focus. For the options parameter you can use Object[] options = { "OK", "CANCEL" };
    It worked nice for me, hope it will for you too.

    Regards,
    Romeo

    I have the same problem. I've tried Michael Dunn's approach above but it doesn't seem to work:Anything wrong here?

    I also tried Romeo Son's technique:
    ... incidentally the last field does not have to be a String - it can be null. However if I leave out the "options" Object[], I don't get focus.

    The problem with this second version is now, after entering text in the text field, pressing Enter doesn't automatically select OK.

    1) Any further ideas on how to get JOptionPane.showConfirmDialog (rather than showOptionDialog, which is more complex) to give focus to the text field?

    2) If I have to use showOptionDialog, how do I make Enter select OK, after entering text (as it does for showConfirmDialog)?

    Thanks

    See Dialog Focus for an approach similiar to Michael's.
