As a short-term fix I think it'd be fine to target gtk2, it's going to be
around for years.
In my opinion, the time of xor rubber banding has passed, it's just too
hard to get it working reliably in complex situations. Once you have double
buffering, background scrolling, overlapping display objec
Hi John, thanks for your comments!
As you say, gdk_ is a thin layer over the X11 drawing system, so
converting that is pretty easy. Gdk has quite a few helpers too, eg.
stuff for rendering a 24-bit image to whatever visual the server has,
so you can save some code there. It shouldn't be a huge
Hi Bernhard,
Thanks for your thoughts! I will look further at GooCanvas and COGL to see
what's there, although my existing app set doesn't really require any
explicit object-oriented support.

Hi Roger,
I moved a medium-sized (100k lines) application from Motif/X11 to gtk+
a while ago.

Hello all,
I am new to this list, please forgive me if this material has been discussed
before. I have a substantial body of Xlib/Motif code that I need to port
to a more modern GUI and have some questions in that regard with respect
to GTK+ and cousins. This code uses Motif for dialog panels, et
