Multiple inherittance in plugins

[KShots]

I think I've already answered this in another threads of yours but anyway :

1. plugin interfaces must be abstract classes (so no inheritance from non-abstract classes, and especially not from QObject)
2. multiple inheritance needs so called virtual inheritance in ancestor classes
3. by design, multiple inheritance from QObject is IMPOSSIBLE so just forget about it and find another design...

Hope this helps.

Hmm... so in this case I should attempt to use boost signals and slots rather than Qt signals and slots for my plugin interface? The only reason I wanted QObject was for signals and slots.

Alternatively, I suppose I could put the signals and slots into my plugin classes and use QMetaObject to parse all the available methods for signals and slots... but that seems a lot of effort. Any other way of doing something similar?
