I guess I don't understand how to use that.  I have no font specified.
ConvertFont returns a similar font style (e.g., Italic) and size to whatever
you put into it.  What I want is to extract the user selected font and size
from the panel.  "selectedFont" does what I want, as long as it has been
used previously with text.  Here is what I am doing:

-(void)addString:(NSString*)string toPath:(NSBezierPath*)path {
    NSFontManager* fmgr = [NSFontManager sharedFontManager];

//    NSFont* theFont = [fmgr selectedFont];
    NSFont* theFont = [fmgr convertFont:[NSFont systemFontOfSize:50]];

    NSBezierPath* stringPath = [string bezierWithFont:theFont];
    NSAffineTransform* tf = [NSAffineTransform transform];
    [tf scaleXBy:1 yBy:-1];
    NSBezierPath* uppath = [tf transformBezierPath:stringPath];
    [path appendBezierPath:uppath];
}

    BTW, the [string bezierWithFont:theFont] is straight out of the
"SpeedyCategories" file in the SpeedometerView sample code.  Works great.
I wish I had found this long ago.
