I think I saw, mentioned in the system requirements, "Windows 2000 or above" or something like that.

I do wonder how cross-platform your code will be, though. I suppose it depends on whether it talks to Win32, or Gtk2, or Qt4, or Qt 5, or Qt 6... etc.

I wonder if FPC+Lazarus could be wired up to Tk so that there was a portable, cross-platform toolkit as well...?



FPC/Lazarus motto is "write once, compile anywhere", so the idea is that you rebuild as needed for different platforms.

It could certainly be wired up to Tk, but what does Tk offer that Qt already doesn't when it comes to a portable cross-platform toolkit?

Small (relatively tiny) code size and simplicity.

Very slow release cycle and long lifetimes. Qt moves pretty quick and this causes problems for downstream projects. E.g. KDE had to keep Qt 5 alive for _years_ until KDE 6 was ready. Rochus Keller has a version of Qt 5 as well. Trinity is still maintaining Qt 3.

Extremely wide cross-platform support, e.g. on the BSDs and some other niche OSes. I think there's even a Haiku version.


TCL/Tk works under XP under the IronTCL release. With modern TLS and all (use http://legacyupdate.net for newer certs).
