kQOAuth is a OAuth 1.0 library written for Qt in C++.
The goals for the library have been to provide easy integration to existing
Qt applications utilizing Qt signals describing the OAuth process, and to provide a
convenient approach to OAuth authentication.

kQOAuth has support for retrieving the user authorization from the service
provider's website. kQOAuth will open the user's web browser to the
authorization page, give a local URL as the callback URL and setup a HTTP
server on this address to listen for the reply from the service and then
process it.
