Signals and Slots - Qt Documentation Signals and slots are loosely coupled: a class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type.

Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time. Signals and slots can take any number of arguments of any type. New Signal Slot Syntax - Qt Wiki The old method allows you to connect that slot to a signal that does not have arguments. But I cannot know with template code if a function has default arguments or not. So this feature is disabled. There was an implementation that falls back to the old method if there are more arguments in the slot than in the signal.

13. Signals and Slots Contd.. Qt supports four types of signal-slot connections: With direct connections, the slot gets called immediately when the signal is emitted. The slot is executed in the thread that emitted the signal (which is not necessarily the thread where the receiver object lives).
