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 concept is that GUI widgets can send signals containing event information which can be received by other widgets / controls using special functions known as ... SignalsandSlots in C++ - sigslot - C++ Signal/Slot Library SignalsandSlots in C++ SarahThompson∗ March2002 1 Introduction This paper introduces the sigslot library, which implements a type-safe, thread-safe signal/slot mech-anism in C++. The library is implemented entirely in C++, and does not require source code to be pre-processed1 in order for itto be used. Threadsafe C++ signals done right : cpp - reddit.com 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. An introduction to Boost Signals | Studio Freya Hi, thanks for letting us know. I’ve fixed it, and lets hope it stays like this. WordPress is stupid when it comes to code in posts. The editor will silently mangle and destroy code, when it’s trying to be “smart”.
