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 Qt5 applications
utilizing Qt5 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.
