Mfc signal slot Our impression when working on the library is that Quality Assurance did not exist in CodeJock.
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.

QTcpServer newConnection slot not being called | Qt Forum If I specified DirectConnection, the slot was called but of course it was called in the context of the thread running my TCP server and not the main thread. Whatever way I choose, I need to get a slot function to run in the context of the main thread which I understand means it must be serviced by an Event Loop in the main thread. Qt 4.3: Signals and Slots 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. How to identify which signal called the slot? | Qt Forum
Qt Toolkit - Signals and Slots Signals and Slots Signals and slots are used for communication between objects. The signal/slot mechanism is a central feature of Qt and probably the part that differs most from other toolkits. In most GUI toolkits widgets have a callback for each action they can trigger. This callback is a pointer to a function. Signals & Slots | Qt Core 5.10 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. c++ - Using emit vs calling a signal as if it's a regular ...

The signal was only emitted, whereas the slot was implemented by the fire department. May be imprecise, but you get the idea. ... If it is possible to use/call a signal ...
