Currently KDevelop QtHelp plugin allow user to load Qt Compressed Help file, like qt documentation, kdelibs documentation, and many other indeed there is a generator from doxygen.
However user can't choose which QCH he wants to load, all QCH file under the dir returned by this command qmake -query QT_INSTALL_DOCS. That's why we decide to improve it.
The main objective is to allow user to select any QCH and load it. To do this job, I wrote a KConfig Module which allow users to select documentation files and associated each one with a name and an icon.
Then you can find documentation by selecting one you want in the combobox
The next objective for this plugin is to integrate GHNS with KNS, in order to share more easily documentation.
