JOptionPane Input Dialog

[Arthur Buliva]

Hi friends,

How does one set a value of a JOptionPane's inputDialog to have a preset String in the input?

This code:

String newWord = JOptionPane.showInputDialog(null,
                "Please enter the New Word",
                "Test Application", JOptionPane.PLAIN_MESSAGE);

Displays the dialog correctly, but I would like the field to bear the old word as a preset string.

Quite odd. There is one method that has the initial value, but only if you don't want to specify the title and icon.

You could use plain old showConfirmDialog though:

JTextField field = new JTextField(30);
field.setText("default value");
Object[] message = {"Please enter the New Word", field};
int answer = JOptionPane.showConfirmDialog(null, message, "Test Application", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE);
if (answer == JOptionPane.OK_OPTION)
{
    String word = field.getText();
}

Moving to Swing / AWT.

Maybe I didn't communicate appropriately. let me use diagrams then.

See the attached figure. When the input dialog is initialised, it displays as in fig 1. My wish is to have it display as fig 2 UPON INITIALIZATION.

not really, there are 6 x JOptionPane.showInputDialog(...)'s
only 3 have a parameter for 'initialSelectionValue'

pick the one best suited, or
use Rob's suggestion, or
roll-your-own showInputDialog via createDialog and setWantsInput(true)

Thanks! This is what I wanted:

String newWord = JOptionPane.showInputDialog(null,
                                        "Please enter the New Word", "My Old Word");
