Exactly. This is because it's interpreted, and I don't believe interpreted
systems are useful for large projects. Hence my reparm

It is also my opinion, and that of the entire Free Pascal team, that they
will have a really hard time getting it to run on Linux by that time.
But then, Borland is a professional company, with capable people so...

I do believe that the kassandra team will be able to get a rudimentary IDE
with designer up and running by the end of this year, though. As far as I know
Sebastian Guenther has the component streaming basically working, the typinfo
unit should be bug-free by now, and he has a binary to text converter for
streamed objects, so you can import Delphi forms. The rest should be pretty

By that time I also plan to have a first working version of TDataset in the FCL,
so... seems pretty much like a 'RAD for any developer' to me ?

Competition gets stiff :-)

I wouldn't bet on it. There are serious problems with that approach, although it
may technically be the preferred one (hell, I would prefer to write a VCL on top
of Qt as well, only Free Pascal doesn't allow C++ objects yet), but the study I
made shows that this leads to serious problems with e.g. C++ exceptions and so
on. Also, don't forget that Object pascal doesn't allow you to declare a C++

In Free Pascal we plan to do support for something like:

TQtObject = Cppclass
   MyField : TMyClass;
   Constructor Create;

so you can declare and create an object of type TQtObject. if you don't have
this you can not instantiate Qt objects yourself, unless you use some C code
to do it for you.

But this is for after version 1.0 (which we're trying to get out ASAP, BTW).

Not true, I thought you could get the widget set for free, but not the source ?
I may be wrong, however. I'd need to check the new licensing model.
