I have found events (signals) extremely handy while working with Qt, and I was missing them much when programming in C++ without Qt. From the other hand, Qt's implementation of signal-slot mechanism has its own limitations - it does not support slot parametrization and usage of signals and slots in interfaces.
Signals and Slots in Depth | C++ GUI Programming with Qt4 ... The signals and slots mechanism is fundamental to Qt programming.
