Hi Max,
start to have a look at IMouse.cpp. The is the baseclass of all CMouse... objects. There you will find mouseMoveEventTrack(...). This does nothing as long as there is no track highlighted. At this point you have to implement a call to CTrackDB, which is a singelton and can be addressed vie static method CTrackDB::self(). In CTrackDB you iterate over all CTrack objects and and compare the mouse position to the pixel polyline of each track (see CTrack::getPolyline). Now you need a way to highlight a detected track and to ask the user for a decision if there is more than one track close by. In my new project, QMapShack (https://bitbucket.org/maproom/qmapshack/wiki/Home), I already implemented that feature. So you might want to look at it too. The point to start is src/mouse/CMouseNormal.cpp. I hope that gives you a good point to start. If you got problems to understand the code, which grew a bit chaotic at some points over the years, to hesitate to ask. I am quite often in the IRC channel. That might proof to be the faster medium.
