I have some experience with tk, gtk, qt and the old athena widgets and even did
my own widget set for (and natively coded in) gnu smalltalk.
For c programming and embedding in other languages I definitely recommend gtk+.
Also if you are concerned with windows/unix portability and licenses, gtk+ works
for you.
For "the old cobol coders" I think it's the best to provide folowing:
- A main window with text canvas, menubar and status line, both can be accessed
and modified via special accept/display additions, the normal display/accept
output goes to to the text canvas (maybe using a fixed font, but user
configurable lines/cols other than 80x24 chars).
This way every cobol program gets a small X11-gui without code changes and this
could be an adaption of the current curses code to x11.
- a way to load these xml ui design files to fire up the dialogs and return the
result to a record in working storage area or by doing calls to get them.
- everything should work just with the gui builder without the need of further
linking and additional non-cobol sources.
I think 80% of the cobol users will be happy with this and its possible to code
this glue layer in short time.
And if nobody does it, I will start this. But I am currently commited in porting
my codebase to OC so It will be April until then.
