Text wrap in JOptionPane?

Question

I\'m using following code to display error message in my swing application

try {
    ...
} catch (Exception exp) {
    JOptionPane.showMessageDialog(this, ex         


        

Answer 1

A JOptionPane will use a JLabel to display text by default. A label will format HTML. Set the maximum width in CSS.

JOptionPane.showMessageDialog(
    this, 
    "
"+exp.getMessage()+"
", 
    "Error", 
    JOptionPane.ERROR_MESSAGE);
