Signals and slots thread safe

Last time I presented basic work on my implementation of Signals/Slots which was thread safe, full-featured (well, is capable of being full-featured), and performed quite well. I had a decent implementation, but there were problems with passing iterators. I have figured out a better solution by making a small change. Signals and Slots with specifiable Executor (Synchronous ...

The thread-safe version will not support grouping and naming of slots, so there is a preprocessor flag "Boost_Signals_NO_Legacy_Support" which changes the template signature of signalN. Signals2 API Changes - 1.69.0 Furthermore, the new namespace and header locations for Boost.Signals2 allow it to coexist in the same program with the original Boost.Signals library, and porting can be performed piecemeal.

Signals and slots is a language construct introduced in Qt for communication between objects[1] which makes it easy to implement the observer pattern while avoiding boilerplate code.The signal/slot system fits well with the way graphical user interfaces are designed. Messaging and Signaling in C++ Qt signal/slot implementation is thread safe, so that you can use it to send messages between different QThreads, this is especially important, as anything UI related should run in the mainSo, slots and signals are normal member functions, declared after the qt-specific keyword signals/slots.

If your slots take too much time to execute then I would suggest that they get executed in a separate thread. However this is not something the event would know about or could actually decide (in an easy way). On top of that, running every slot in a potentially different thread requires you to make slots thread safe and it could hurt performance.

Indeed. Qt signal/slot are specifically designed to make threads easy. You just write the code with signals and then, depending on the thread where the objects are created at the beginning (or to which thread they are moved), same signals act as direct calls or as message queues.

My main design goals are: simple but still offering some features and thread safe. My personal opinion on a Signal/Slot system is that emitting should be as fast as possible. Because of that I try to keep the slot list inside the signal tidy.
