[Interest] Linking to offline Qt documentation

[resurrection at centrum.cz]

Hi,
 
I have a documentation for my projects created with qdoc. Since I am using Qt stuff here and there I link them in my docs:
 
e.g. \l QVariant
 
To make it work in the qdocconf (as per manual) I have:
 
indexes = $QT_INSTALL_DOCS/qtcore/qtcore.index
 
This seems to produce links to the Qt *online* documentation only. In Qt Creator the context help (F1) works fine for my classes and for Qt classes. However the links from my documentation to the Qt classes do not use the offline documentation loaded in Qt Creator (even though it has been linked to) but rather goes to browser and the online documentation.
 
I suspect that this behaviour is due to `url` variable being set in the Qt documentation so that anyone linking with it will get it prepended to any link. It probably cannot be influenced in built documentation.
 
Is there a way to tell qdoc to produce offline links when linking with the distributed docs?
 
Thanks!
Michael
