Yes, I've just found the problem

grabMouse cannot be used, you're right, but my problem was in boundingRect method.
I returned:
Qt Code: 
  1. QRectF boundingRect     () const { return QRectF(); }
To copy to clipboard, switch view to plain text mode 
and this of course means that the buttons are 0 sized.

Now I return:
Qt Code: 
  1. QRectF boundingRect     () const { return QRectF(QPoint(0, 0), mVals.qsSize); }
To copy to clipboard, switch view to plain text mode 

and everything works fine

Thanks anyway.
