Qt signal slot infinite loop

Signals and Slots. In Qt, we have an alternative to the callback technique: We use signals and slots. A signal is emitted when a particular event occurs. Qt's widgets have many predefined signals, but we can always subclass widgets to add our own signals to them. A slot is a function that is called in response to a particular signal.

Signal and Slot Two Threads | Qt Forum When I change the signal and slot from QString to char* the main thread stays alive, just like expected. When I printed the char* in the working thread before entering the infinite loop, it only shows bogus.

Signals & Slots | Qt 4.8

The signal and slot approach works well when the objects live in the same thread, but in this case it generates a loop as you can see in the output. What I'm expecting is the first 4 rows of the output and stop, but with this code the output is an infinite loop. Thank you for your help. V. myclass.cpp

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.
