Hi Valeriy,
simpler in this case is to include a LiveObjectTimer as datamember
in your LiveObject class and redirect all timer functions via this special
timer. In the ctor of the LiveObjectTimer you pass a pointer to the
LiveObject and you should be able to do what you want without big
changes.
Cheers, Fons.
