I am trying to modify the layout of JOptionPane.showOptionDialog(), is this possible? Here is my code:

import javax.swing.*;
 
public class Test {
 
	public static void main(String[] args) {
		
		JTextField height = new JTextField(3);
		JTextField width = new JTextField(3);
		JTextField mines = new JTextField(3);
		
		String s0 = "Height:";
		String s1 = "Width:";
		String s2 = "Mines:";
		
		Object[] options = new Object[] {s0,height,s1,width,s2,mines};
		JOptionPane.showOptionDialog(null, options, "Custom Field", JOptionPane.OK_CANCEL_OPTION, JOptionPane.PLAIN_MESSAGE, null, null, null);
		
		System.out.println("height = " + height.getText());
		System.out.println("width = " + width.getText());
		System.out.println("mines = " + mines.getText());
		
	}
	
}

This produces a JOptionPane with the following layout

Height:
____________
Width:
____________
Mines:
____________
okButton cancelButton

My goal is to produce the following layout

Height:________ okButton
Width:________ cancelButton
Mines:________

Is this possible?

 

 

Very little is impossible

The tough way: create and set your own OptionPaneUI

The easier way: create and display your own modal JDialog.

I second Darryl's second recommendation: create your own JPanel with its own OK and Cancel buttons and place it in a JDialog.

 

 

Wow, awesome! I didn't even think about it that way. So, I would put my JPanel in the Object[] array?

 

 

If you think about the options or even the message argument of the JOptionPane.showXxxDialog() methods, no: I think they meant creating a JDialog, and add your custom panel as the dialog's contentPane.
Note that this is one of the rare cases (in my humble but stubborn opinion) where creating a JDialog is preferrable to tweaking the (otherwise preferred way) JOptionPane into something it was not designed for.

Note that you might experiment with the DEFAULT_OPTION option type, which is supposed to not provide the YES/NOOK/CANCEL row, and provide your own panel, or array of panels, but that would be awkward to have to deal manually with the OK and Cancel buttons (which JOptionPane is designed for), at this point it's merely clearer to use a plain JDialog.
