Zoom to center of object

Hi

I was wondering if anybody has a "zoom and center" function? I'm trying to simulate the Ctrlkey action, but using a button. The problem is not the zoom but the centering of the object... What is the best way to do it? Using viewbox or currenttranslate and currentscale?

Any suggestions would be appreciated!

Thanks!

Hi Michel
Thanks for the reply. I looked at this example but it doesn't solve my problem. I need my "button-zoom" to work exactly as "CTRL-key" zoom. I can't find any examples where it center's properly to where I have clicked.
