Hi,

it starts to work. My last error was caused by linker, and I was
unable to force the linker to find the right file, so I went
around this problem, by putting the .cpp file inside .hpp. 
The problematic place is marked by line 
//////////// FIXME - a .cpp file?

Another change was to flatten the tree. It was a bit too cumbersome
for me right now to browse all the subfolders. I don't care how it
should be done, main point right now was to get it to work.


So least now we have a working example.

You can run it by:
  make
  ./main

Just be sure that you have qt4 development files installed, or it
won't compile.

When a window opens, click in the menu "File->Open".
On the bottom of this dialog box pick "TXT boost::serialization files (*.txt)".
Then open demofile.txt.

That's how it works:
  The file is loaded for HDD with boost txt serialization, then the
  file is saved to QT with qt_tree serialization.

It even doesn't work in opposite direction, just displaying. Cannot save.


Last time (years ago) I started looking into qt3 tree view, but I
haven't done it. If switching yade into qt4 turns out to be too
difficult, then maybe we could change qt_tree.hpp to use qt3.


Please at least have a look if my example works for you.

Imagine - if we get this to work, we will have a browsable and
unfoldable tree of Scene! Or any other object that you right-click
(or something) in the QGLviewer window ;)

best regards

PS: the excessive columns "Version", "Tracking", etc.. are internal
fields of boost serialization. And their display can be suppressed,
in qt_tree.hpp:44 by returning 2. instead of 7
