Welcome to the Katie wiki!

If you are wondering about the source incompatibilities and the solution for them:

• Some headers are missing
• QStyleOption classes
• QIconEngine, QIconEnginePlugin and QIconEngineFactoryInterface classes
• QImage::loadFromData() and QImage::fromData()
• QMimeSource and QDropEvent
• QSharedPointer and QT_SHAREDPOINTER_TRACK_POINTERS
• QStylePainter::drawItemPixmap, QStyle::drawItemPixmap, etc.
• QStringBuilder
• QThreadStorage
• ...

Get started by reading about:

• The build system
• Building, installing and using
• The problems of Qt, not just 4

And in case you are interested, here are some statistics about the project source code:
