I had originally planned a high level, C++, object-oriented library for
object-oriented access to graphics <i>widgets</i>.
However, C++ compilers are not available for some of the targets supported by NuttX.
So I have decided to implement the entire solution in C.
That decision makes the solution somewhat more difficult to work with, but supports all platforms.

At this point, the amount of C in the implementation would make conversion to C++ a
more difficult job.
I leave the C++ widget interface to any contributor who may have an interest in such things.

This directory holds NuttX graphic packages. Not all of these packages are implemented
at the present, but here is the longer term roadmap:
NXWIDGETS - I had originally planned a high level, C++, object-oriented library for
object-oriented access to graphics widgets. However, because C++ compilers
are not available for some of the targets supported by NuttX, I have
decided to implement the entire solution in C -- that makes the solution
much uglier, but works fine on all platforms.
NxWidgets - NxWidgets is a higher level, C++, object-oriented library for object-
oriented access to graphics "widgets." NxWidgets is provided as a separate
package. NxWidgets is built on top of the core NuttX graphics subsystem,
but is not a part of the core graphics subystems.
NXTOOLKIT - A set of C graphics tools that provide higher-level window drawing
operations. The toolkit can be used for window-oriented graphics
without NXWIDGETS and is built on top of NX.

NXFONTS - A set of C graphics tools for present (bitmap) font images.
NX - The tiny NuttX windowing system. This includes both a small-footprint,
single user implementaton (NXSU as described below) and a somewhat
larger multi-user implentation (NXMU as described below). Both
conform to the same APIs as defined in include/nuttx/nx/nx.h and, hence,
are more-or-less interchangable. NX can be used without NXWIDGETS
