[Eric] Migrating from eric 3 / QT 3 to eric 4 / QT 4

[Stephen Schaub]

Thanks, Detlev. Your info was helpful. My mistake was in trying to use
the designer to set up the events to be generated in the Python code.

Are there any tutorials that show how to use Eric to do PyQt
development with the Designer integration, etc.? If not, maybe I
should write one, once I get it figured out...
