It is the population of the models paired with the way Qt4 accesses the modell. > > b) Resizing the projectbrowser seems to update very slow, could that be > due to debug builds of PyQt and sip?

All in all I have the impression, that Qt4 is slower than Qt3. I have observed this with other (pure) Qt applications as well (both at work and at home, both on Linux and on win32). I got the impression, that the problem is worse on Linux. > > Andreas Detlev -- Detlev Offenbach [EMAIL PROTECTED] _______________________________________________ Eric mailing list [EMAIL PROTECTED] http://www.riverbankcomputing.com/mailman/listinfo/eric
