Know how wide text will be on a Canvas

[Sean]

Hey guys, 

I was wondering if there was a way I can set the font in a canvas:

m_context.setFont("bold 12px sans-serif");

Then take some text, like Hello World! and know how many pixels wide that will be? I have a set space on my canvas, and I want to maximize the size of the text or justify it correctly. So if I know Hello World will take 50 pixels in the X-direction, but I have 75 pixels, I can start it at x+(75-50)/2.0 pixels and have it centered. 

Thanks!

Ah, thank you!

Thanks for giving me a reason to go looking for it. I added the
incubator Canvas to my app a few years ago; I hadn't noticed that GWT
now includes an official Canvas implementation (as of 2.2,
apparently).
