[Qt-jambi-interest] Demos bug

[Raffaele Magliocco jr.]

Just thinking out loud....

note 1:
Qt 4.6 now uses a QDirIterator to read through the file system.  But
QDirIterator doesn't see our QClassPathEngine which inherits from
QAbstractFileEngine.

I think we can add a custom iterator to the QClassPathEngine but I also
we need to add a wrapper for QAbstractFileEngine::beginEntryList
(currently rejected in the generator xml)

note 2:
Qt 4.5 called the appropriate entryList method directly. No Iterator.

note 3:
All methods in QDir seem to be working that don't rely on QDirIterator.

note 4:
If a path is already absolute, calling QDir.makeAbsolute() should have
no effect on the path?  (referring to what Bruno mentions below)

Regards,
Ralph
