  2. What’s PyDVT? • Package containing Python base classes for data visualization applications.

  3. Objective • Easy remake of existing ESRF graphical tools in Python. • Easy creation of simple graphic applications in beamlines (on-line acquisition) • Standarize graphical application development • Attempt to share model with Scisoft (off-line analysis).

  4. Requirements • Tk or Qt? GUI toolkit independent. • Generic data abstraction layer. • Independent and extensible modules. • Performance. • Multi-Platform. • Easy of use. • Simple and complex cases.
