Enable text highlighting in swing message-box

Question

Say i'm using the following code to prompt an error message in my simple swing application:

JOptionPane.showMessageDialog(null, message, "Error", JOptionPane.ERROR_MESSAGE);

Is there any way I could make it possible for the user to highlight text sections (for copy/paste purpose)?

Many thanks.

Answer 1

try this

 JTextArea textarea= new JTextArea("add your message here");
 textarea.setEditable(true);
 JOptionPane.showMessageDialog(null, textarea, "Error", JOptionPane.ERROR_MESSAGE);

Answer 2

JOptionPane can be constructed with any object, not just a string message. So you could construct a JTextArea and pass that to the JOptionPane as your message. That should allow copy paste.

Answer 3

If you object to the white background shown by the default JTextArea, you can set the JTextArea background color equal to the JOptionPane's background color.

String title = "foo";
String message = "Select me";

JTextArea msg = new JTextArea(message);
JOptionPane pane = new JOptionPane(msg, JOptionPane.INFORMATION_MESSAGE);
msg.setBackground(pane.getBackground());
JDialog dialog = pane.createDialog(null, title);
dialog.setVisible(true);
