Generating the KDE API docs with kdoc would help. Cross-referencing to
Qt docs can be done with qt2kdoc and included. The inheritance class
tree will show you where KDE classes derive from a Qt class that
originally served as providing the base functionality. KDE classes tend
to specialize a Qt class (like the completion combo for instance).

Hmm..a complete tree of Qt and KDE classes alltogether wouldn't be too
bad....
