showInputDialog

[Brian Lemieux]

What is the code to make an Input Dialog box with multiple input boxes?

I want to get input into 4 input boxes found on an Input Dialog box and
capture those into their own variables and then pass then into an object.

I just need the code to create an Input Dialog with more than one input box for starters and from there I think I can get it.

 JoptionPane.showInputDialog()

Sounds more like something for the Swing forum, so I shall move you.

You will have to go through the JOptionPane class, but I can't remember any methods which take 4 inputs simultaneously. You can call showInputDialog 4 times; that is quite easy.
By the way: If you are not using a Swing GUI you will probably need to pass "null" for the "parent" argument (usually the 1st argument). Then the input dialogue box will appear in the middle of your screen, (and might hide behind any other windows there!)

And when you go to the API you find this link to the Java Tutorials, which will probably be very useful to you.

put 4 textfields on a JPanel
add the panel to an optionPane (message or confirm), as the 'object' arguement

when the optionPne closes you extract the values from the 4 textfields

[Rob Spoor]

showConfirmDialog will be better than showMessageDialog because you want to know if the user presses OK or not. Other than that Michael is right: just pass the JPanel as the message object.

Mr. Dunn is correct, and his way is probably best because you can control the layout of the panel, but you can also simply pass an array of text fields to JOptionPane.

You can even interleave Strings in the array. For example:

JTextField makeField = new JTextField();
JTextField modelField = new JTextField();
JTextField yearField = new JTextField();
JTextField colorField = new JTextField();
Object[] message = new Object[] {
"make", makeField, "model", modelField, "year", yearField, "color", colorField };
int r = JOptionPane.showConfirmDialog(this, message, "4 input boxes ", JOptionPane.OK_CANCEL_OPTION);
 
if (r == JOptionPane.OK_OPTION) System.out.println("year is "+yearField.getText());
