Hello,
I need a combiner which executes only the slots within the highest group.
How to access to group in the combiner?
What happens with the input iterators if signal::disconnect_all_slots() gest called within the combiner?
someting like this:
struct combiner
{
template< typename It >
void operator( It i, It e) const
{
// iterate over slots
// execute only slots of highest group
}
};
signal< void(), combiner, int, greater< int > > sig;
sig.connect( 0, slot1);
sig.connect( 1, slot2);
sig(); // only slot2 gets called
regards,
Oliver
