Re: Porting DDD to other widget-sets (gtkmm?)

[Peter Wainwright]

I have been looking at the possibility of a gtkmm port for 18 months,
and am putting together some code in "branches/gddd".  The solution I
eventually came up with was an object-oriented GUI interface, modelled
on a small subset of gtkmm, which would act as a shim between DDD itself
and the underlying widget sets.  Hopefully such a thing would allow
Motif, GTK and perhaps even Qt ports to exist.

However, as Andrew has pointed out, the GUI calls are scattered
throughout DDD so that tracking them down and redirecting them through
the new abstract interface has been time-consuming and is far from
finished.  Particularly because my first attempt was a bunch of dirty
macro hacks which I have now abandoned.

A short introduction to this work can be found on this site:

(also available as a Docbook XML file in the "docs" subdirectory of the
source).  I intend to add to this, in particular there should be some
information on the modifications I made to the MMDesc type in order to
generate the new-style widgets.
