That must have been over a year ago then I guess. Qt is licensed under
LGPL, so you can freely use it even for commercial applications. That
was also possible before then, but it was GPL so you had to offer all
your source code too (depending on how you interpret the GPL terms, but
that's even more offtopic now).
As for doing drawings, graphs etc as you mentioned - that is all
possible
with Qt-Embedded, fpGUI and MSEide. Just to be clear, the latter two
can
also be used for desktop apps, they are not limited to embedded
devices.
I'm pretty sure that Qt-Embedded is a superset of Qt, so it should be
possible to reuse the same code. The strong point of Qt-embedded is,
that it *doesn't* use the X server but uses the framebuffer and
implements an own windowing system. So you are pretty much independent
from many other components. Also Qt-embedded (as does Qt) comes with
lots of helper libraries (Networking etc.) that really give you a
coherent framework for app development.

Andreas
