Dia internals

[Russell Shaw <rjshaw iprimus com au>]

Hi,
I'm trying to see how dia works using gdb/ddd to learn something
about graphics programming and object-oriented techniques in C.

I compiled it with CFLAGS=-ggdb and can step thru the
source code with ddd.

How do i get dia into synchronous mode when using ddd?
Where is the call-back function for the File|New menu
so that i can set a breakpoint there?
I'm using debian-2.4.20 and gvim.
