[Eric] Re: Re: QT Designer & Plugins on PyQT

[Сергей Гринько]

This problem correlates with the problem:
    Error at startup item "Generate Dialog Code ..."
they need to be addressed in an integrated manner.

I suggest to add at the level of the project, two new properties:
1) "PYQTDESIGNERPATH" - the way the search module plug-ins for
QT-Designer (custom widgets)
2) "PYTHONPATH" - module search path for the realization of
QT-Designer (custom widgets)
3) and to add management os.chdir ()

Waiting for the new release, thanks!
