Ok, got it. I don't have an immediate answer. But as it happens I have
a job to do with GWindows at the moment, so I'll see if I strike the
same problem. No promises on a solution.

Maybe off-topic from the initial question, but just for your information,
an effort is currently made to create a binding to Qt. Yes, it's C++,
so it's much more difficult to achieve. No, it's not yet ready to be used,
and as long as I'm the only developer it won't be finished any time soon.
But I've already manage to re-create in pure Ada the 7 first tutorials,
the 8th should be done, well, next week I hope.
Side note, it compiles and runs on both Linux and Windows (using MinGW).
Other platforms are yet to be tested though.
If you're interested : http://qt4ada.sourceforge.net

Though GTK+ performs quite poorly on Windows platform. And overall, when
its documentation tells you that you fundamentally cannot save and restore
the position of a window, what could you say?

In my opinion it must be 100% Ada. I don't believe in C.

Obviously.

So if you require portability across platforms, don't use GWindows.

On the other hand, making the GUI lib portable means using only those
features common to all of the targeted platforms.

So if you want your application to be able to take full advantage of
the Win32 API, use GWindows.

So use GtkAda on Windows as well.

Are you aware of this qtada binding:

http://freehost07.websamba.com/guibuilder/

I downloaded it but the zero docs prevented me of trying it. It is in my
todo list for spare time. I find GtkAda extremely unpleasant to work with,
and I remember from early times that Qt programming in c++ was very
straightforward. In any case I like much better the looks of Qt apps over
Gtk+ ones. Or at least kde over gnome ones (yikes... not trying to start a
fw here!).

In any case keep us informed of your progress.
