No, if you use measureText it only measures the text according to the parameters that you supply, it doesn't take into account any properties other than font and font size AFAIK, whereas formattedWidth measures the text in the field along with the margins effectively giving the field width.

Yes, measure text can take the font/size from different controls too, so if the field doesn't exist yet you can use a reference to another control, group, card or stack.

e.g. If your card 1 was set with a font of Helvetica and a text size of 14…
	put measureText("Measure this text",card 1) into theTextWidth
… theTextWidth would equal 106 and "Measure this text" does not need to be on card 1.

Try it, it works very well from my experience, although I suspect there may be some caveats that I haven't discovered yet.
