The library is implemented entirely in C++, and does not require source code to be pre-processed1 in order for itto be used. How Qt Signals and Slots Work - Part 2 - Qt5 New Syntax
Signals and slots is a language construct introduced in Qt for communication between objects 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 slots. This is similar to C/C++ function pointers, but ...
