[PyQt] problems with PyQt book custom view examples [Win7]

[Romi Agar]

For example chapter 6: imagechanger_ans.pyw. It remebers the window size and
log window position, but not the last accessed images.
I think that this has something to do with using QStrings.
I just tested the chapter 16 carhirelog.pyw example. By default it does not
show the content of License, Customer and Notes columns. But what do they
have in common? In CarHireLog class, they are all stored as QStrings.
Removing the conversion to QString from the initializer and voilaa - it
works. Maybe the recent files problem comes also from QString usage or
QStringList conversion - haven't tested yet.
