Question

I’m looking to have text display vertically, first letter at the bottom, last letter at the top, within a JLabel. Is this possible?

Answer 1

I found this page: http://www.java2s.com/Tutorial/Java/0240__Swing/VerticalLabelUI.htm when I needed to do that.

I don’t know if you want the letters ‘standing’ on each other or all rotated on their side.
