how to change the width of Joptionpane.showInputDialog?

Question

Would you like to know how to increase the width of the inputDialog inbox? I am using the code below to open the dialog box to edit an information called "title", is working, but the title can be a little long and so I would like the dialog box to be wider.

String answer = (String)Joptionpane.showInputDialog(null,"Title Edit:", "Title Edit",Joptionpane.PLAIN_MESSAGE, null,null,"Title");

UIManager is a utility class of the Swing library, in which you can change the properties of the elements by setting values through keys and values (as well as a Hashmap, for example).

To change the minimum size of an Optionpane, you can change the property OptionPane.minimumSize, staying that way:

UIManager.put("OptionPane.minimumSize", new Dimension(500, 50));

String resposta = (String)JOptionPane.showInputDialog(null,"Edição de título:", "Editar Título",JOptionPane.PLAIN_MESSAGE, null,null,"Título");

You can see the documentation for the Uimanager class here, and the properties here.
