Bernd N and I have been through this -- there's no reliable way to this, unless you have a known number of lines, and a fixed point size, line height, etc. Bernd wrote a method that uses the pixel rect of the text via snapshot that can work. My solution is to use buttons since those can display centered text, but that may not be an option for some implementations.
