As we have recently gone through this process for MusE, which is a
fairly large project, I thought I would chime in.
Getting the sources to compile using the compatibility stuff (qt3to4
and -lQt3support) was actually easier than we anticipated. We got
basic functionality restored fast but several things didn't work right
in this state.
I believe the compatibility library should be seen as a stepping
stone, there were several instances where moving a widget from a Q3
compatibility widget to a full Qt4 widget things started working
correctly again.
And yes, there was a bit of work removing the support for Q3
compatibility library but it turned out very nicely indeed.
Regards,
Robert
