Is there a way to only have the OK button in a JOptionPane showInputDialog (and no CANCEL button)?

Question

I\'ve seen that this is possible in other types of dialog windows such as \"showConfirmDialog\", where one can specify the amount of buttons and their names; but is this sam

Answer 1

JOptionPane.showInputDialog() returns the string the user has entered if the user clicks "OK" and returns null otherwise. See this:

Returns: user's input, or null meaning the user canceled the input

You can't do this using showInputDialog()

However, you can use JOptionPane#showOptionDialog():

Object[] buttons = {"OK"};
int res = JOptionPane.showOptionDialog(yourFrame,
                   "YourMessage","YourTitle",
                   JOptionPane....,
                   JOptionPane..., null, buttons , buttons[0]);

As @HovercraftFullOfEels stated on the comments, you can add JTextField to the dialog and achieve this.
