Making a JOptionPane with 4 options

I need to make a custom dialog with 4 options but as far as I can tell you can only have one with three options. Here is how I would make an option pane with 3 options:

Frame refFrame = DialogUtils.getReferenceFrame();

///TODO:
/// - Use DialogUtils
int option = JOptionPane.showOptionDialog(refFrame,
msg,
rsc.str("918"),
JOptionPane.YES_NO_CANCEL_OPTION,
JOptionPane.INFORMATION_MESSAGE,
DialogUtils.INFO_ICON,
options,
options[0]);


But I could not find some sort of open ended substitution for YES_NO_CANCEL_OPTION. Is there a way to make the JOptionPane allow four choices?

Answer

You can use any of the JOptionPane's option constants, you just need to supply a options array of size 4:

public static void main(String[] args) {
    String[] options = new String[] {"Yes", "No", "Maybe", "Cancel"};
    int response = JOptionPane.showOptionDialog(null, "Message", "Title",
        JOptionPane.DEFAULT_OPTION, JOptionPane.PLAIN_MESSAGE,
        null, options, options[0]);

    // Where response == 0 for Yes, 1 for No, 2 for Maybe and -1 or 3 for Escape/Cancel.
}
