c++ - Efficiency of Qt Signals and Slots -


i browsing methods inside of qmainwindow , noticed parts (such resizeevent , winevent) not implemented signals rather have inherit class able override them.

my question is, how efficient signals , slots , possible implement these types of functions signals other classes can subscribe to. instance, inside of high performance game engine.

from recall, trolltech stated signal/slot call 10 times slower virtual call. should able process tens, if not hundreds of thousands signals per second.
