Signals and Slots Mechanism - Video

"When the user clicks on this button, run this code" is probably one of the oldest problems in programming; many solutions have been proposed through the years. Qt has its own solution: the signals and slots mechanism.

When the button gets clicked, it emits a signal telling everyone (who's listening) that it has been clicked by the user. The slot implements the code we want to run. And the final magic: a connection gets established between the signal and the slot. This video explains how to achieve such a connection from C++.
