Well, I used my GTK 2 code on Windows and there were no problems at all.
And note that I initially wrote and tested that code on Linux, not on
I used GTK libraries as installed by GIMP for Win32 installer
[http://gimp-win.sourceforge.net/], libraries there are partially taken
from libraries at [http://gnuwin32.sourceforge.net/] so these are really
correctly compiled, official GTK 2 libraries for Win32. You don't need
anything special for FPC to work with GTK 2.
As for #ifdefs between Windows and Unices -- there really aren't many on
GTK level. Calling conventions in compiled Win32 libraries that I
mentioned above are always cdecl, just like under Unices, so there's
also no problem here. GTK+ reference has a page about "Win32 specific
issues in GTK"
[http://developer.gnome.org/doc/API/2.0/gtk/gtk-windows.html] but there
is nothing really important for "normal" programs.
In summary, there are no "known general problems" with GTK 2 + Win32 +
FPC. Everything should work just as under X-Windows under Unices.
Janusz: I think that you must reveal in more details where are your
problems. Show us some piece of code etc.
