Hi!

How about this:

create a base class for timed objects:
class TimedObject
{
public:
    virtual void tick() = 0;
};

Every sprite inherits from this.

For every different timing interval you create an instance of the following 
class:

class TimeManager : public QObject
{
Q_OBJECT

public:
    void addTimedObject(TimedObject* to)
    {
        if (to != 0)
        {
             // add to to inetrnal list
        }
    }

    void removeTimedObject(TimedObject* to)
    {
        if (to != 0)
        {
            // remove to from inetrnal list
        }
    }

protected slots:
    // connect this to timeout() of a QTimer
    void slotTimeOut()
    {
         // iterate through list
         // call tick() on each element
    }
};
