Align the text/message of a JOptionPane

  • 772

I have several JOptionPanes that display messages, example:

enter image description here

JOptionPane.showMessageDialog(loginFrame, "          Login Successful");

When I write the message like in the example, I have to put a space before Login Successful so that it looks aligned in the middle of the dialog if I don't the message looks like this:

enter image description here

And I don't like it aesthetically.

Is there a way to align the text/message without having to do it manually with whitespace?

EDIT:

Try this:

JOptionPane.showMessageDialog(loginFrame, new JLabel("Login Successful", JLabel.CENTER));

And it doesn't work, the result:

    JOptionPanehas an JLabelinside, so we can create a new one, instantiating it again, and giving it whatever attributes we want:

    JOptionPane.showMessageDialog(loginFrame, new JLabel("Login Successful", JLabel.CENTER));

  2. I could propose a quick solution, friend, but it implies eliminating the icon that has a JOptionPane.showMessageDialog(parameter) by default , which is the one that appears here:icon

    for this you have to remove the icon by inserting these parameters in the method: JOptionPane.showMessageDialog(loginFrame, new JLabel("Login Successful", JLabel.CENTER), "Messaggio", JOptionPane.PLAIN_MESSAGE);

    You would have something like this:

    many years late, but there it is XD
