Hi Everyone,
I was doing something like (lat, lon)->height, with height mapped
to Display.Text. This worked ok, and I could even colour it with
my favorite colour. Then I did a setFont() on the textControl,
and apart from setting the font properly, it turned my text white!
This is not seen when I rewrite my program to have
n->(lat, lon, height).
Attached is a sample program to show this. Uncomment the setFont()
line to turn the text white.
Have I got something wrong here, or is this a bug?
thanks,
Andrew.
