My second guess at what's going on "wrong". I think maybe it isn't working as wrong as you think. I've seen other "production" X programs that have the behavior of resizing buttons with the "window" . Generally, it appears most people use something above Xt (like motif) as the geometry manager. motif supplies a number of controls for the widgets placement, alignment, size, gravity, etc.

I searched throught the header files (64 bit) but could find no reference. I also tried XmCreateMenuBar(...) but the function was not recognised. I didn't deliberately install Motif, so guessed that it wasn't an automatic install by SuSE (by the way, I am using 9.1) I also tried XtCreateManagedWidget(... XwformWidgetClass, ... but no XwformWidgetClass

Do you know what I need to 'install' to 'access' the above items?

To get motif development I had to install openmotif via Yast. It was on the 9.2 DVD. 9.1 should have this, or lesstif.

Thanks for the references - I will get back to you in 2007 when I've finished reading them. :-) Seriously, I will never get through this lot, but they are a great resource, and I will get started.

I am concerned about using Motif: I am still under the impression that Motif is proprietary software.

As far as I understand, openmotif fixes that problem.

(Am I correct in assuming that code written using Motif resolves to only calling the user's X11 routines? )

The libraries linked to the program handle the Xm functions which call the Xt and X functions. Assuming the libraries are statically linked, it should have everything self contained, so it should run anywhere any X client could run. (In other words, a program using motif libraries should not be dependant on running under the motif window manager. At work I run a modeling/simulation program written for motif under Open Look. )

I feel that I would be happy enough just using the X, Xt, Xaw and Xw functions.

I am using: gcc MyProg.c -o MyProg -I/usr/X11/include -lXt -lX11 -L/usr/X11/lib64 -L/usr/X11/include/Xw -lXaw -L/usr/X11R6/lib/ -lm Does this look okay, or have I over-done things/redundancy?

I can't address the right now at work. It might help if I had the entire program to compile on my setup.

And what is Xaw3d ?

I THINK that is Xaw with a 3D look (border hilights). I do know I've read you shouldn't mix Xaw and Xaw3D. I've also heard Xaw doesn't play well with others.
