Qt's doc says something related : http://doc.trolltech.com/3.0/signalsandslots.html and from http://doc.trolltech.com/3.0/templates.html Aside: If you have a signals and slots connection in a tight inner loop of a performance critical task and you identify this connection as the bottleneck, think about using the standard listener-interface pattern rather than signals and slots. In cases where this occurs, you probably only require a 1:1 connection anyway. For example, if you have an object that downloads data from the network, it's a perfectly sensible design to use a signal to indicate that the requested data arrived. But if you need to send out every single byte one by one to a consumer, use a listener interface rather than signals and slots. -- Guillaume. http://www.telegraph-road.org
