All,
I have been following FLTK for several years. When I started out using
FLTK, I chose to use 2.x because of several reasons:
1. A built-in hierarchical tree browser widget
2. A separate namespace
However, when it became clear that I would not achieve stability on
Linux and Mac with FLTK2 I switched back to FLTK 1.1.x and have been
mostly happy (using the FLU tree browser). I have not yet explored
switching to 1.3.
I would love to see 1.3 adopt the fltk namespace of the 2.x series. In
my application, as I was switching from FLTK2 to FLTK1.1.x I made some
header translations that helped me write code without a lot of #ifdef
conditionals. Might something like this be useful (perhaps in reverse of
what I have posted below) to help transition programs from 1.1.x to
1.3.x using the fltk namespace? I include a sample below. I include
this file and can use fltk::functions in place of Fl_functions. I think
using the C++ namespace is cleaner, and easier to type. This type of
translation will be much easier if the function semantics do not change.
Of course, I also vote for a built-in hierarchical browser for FLTK 1.3.

/* This header file is used to simplify some differences between FLTK
1.x and FLTK 2.x. It converts some of the old 1.x Fl_* names to be the
same as the fltk::* names found in 2.0, where other semantics are the
same. The new way is much cleaner. */
