Re: PyDEV + PyROOT

Hello Wim and Brett,

Thank you for your comments.

Since PyDEV plugin does not read $HOME/.pystartup, touching functions/ classes is not a solution. Because it analyze the syntax and structures of python modules to be imported not on-the-fly but when I set the PYTHONPATH from Eclipse's preference panel.

This is an error from the auto syntax checker in Eclipse + PyDEV.

I agree that auto loading of all classes when importing ROOT, is not sufficient. Therefore it will be good idea if I can load all classes only when importing ROOT from Eclipse + PyDEV.
