Re: C++ and GNOME or Motif

[Jim Kroger <kroger Princeton EDU>]

Thanks for the reply, Dave.

I am writing a program to read data from files, do various 
computations, then construct and display graphical depictions of
the results. For example, I may need to depict a rotatable solid 
object, with shape or colors changing in time to reflect statistical 
trends in the data. I program in C++, and plan to use OpenGL for the 
graphics. I will work in Linux but need the program to be as portable 
as possible to other *nixs using other windowing environments.

I have no Unix programming experience, leave alone X Windows, Motif, 
etc. A little research has shown that Motif is being superseded by 
GTK+, etc.

Two reasons I want to use Motif: there is a good book on using OpenGL 
with X Windows/Motif (Kilgard, I think); and it is pretty universal.

The reason I may not want to use Motif: I've been told that it is 
very unfriendly, because of the nature of it's event loop, to 
object-oriented programming.

I don't understand the latter issue, and I guess that's what I'm 
trying to understand.

Thanks
Jim
