Hi, I think I went with bbox for the Canvas, because it gives BOTH height and width. The fontMeasure says it measures width, and seems to be oriented towards text widgets, that do vertical spacing automatically for you. When you are putting lists on a Canvas, you need to take care of the vertical spacing yourself. I chose the W, since it seemed the biggest( not in honor of George W. Bush:-) ). That way, I can do one calculation for my vertical spacing (assuming font is constant)..... get the bbox of W, take the diff of the y's....add 2 pixels for line spacing.
