C++11/Qt & Dropbox v2 API in dropboxQt

[osoft]

We recently uploaded to github Qt5 adaptation of Dropbox v2 API, see https://github.com/osoftteam/dropboxQt and homepage http://prokarpaty.net/dropbox.php

Would be interesting to hear valuable feedbacks.
It's called dropboxQt. What is special about this code is that it was mostly generated from something called Dropbox Stone documentation. It is kind a big, because API itself contains about 400 classes, but we tried hard to bring structure into code and create clean interface.

Some details about implementation - we used lambdas for slots, unique_ptr and factories for result types, also exceptions are heavily used (there are couple dozen of them) because they fit into Dropbox solutions. There are also convenience functions that don't throw exceptions but provide top level access, for example:

bool downloadFile(QString dropboxFilePath, QString localDestinationPath);
bool uploadFile(QString localFilePath, QString dropboxDestinationPath);
bool fileExists(QString dropboxPath);
bool folderExists(QString dropboxPath);
