One way is "after the fact"--e.g., I output the text I want to
display into a memory stream, stuff that into a resizable Text
object, and then ask the Text object how big it is:

	id t;
	id fwfont;		// a fixed width font
	NXStream *aStream;	// stream containing text data
	NXRect br;
	// some arbitrary minimum size
	const NXRect trect={ { 0.0, 0.0 }, { 93.0, 24.0 } };

	t=[[Text allocFromZone:[self zone]] initFrame:&trect];
	[[[[[t
	    setMonoFont:YES]
	    setHorizResizable:YES]
	    setVertResizable:YES]
	    setNoWrap]
	    setFont:fwfont];
	[[t readText:aStream] sizeToFit];
	[t getBounds:&br];

br.size contains the desired information.
