The Slot in Qt
The slot is a hockey term for the area of the ice where the puck has the best chance to go into the net without being deflected. A good center or winger can exploit the slot by skating into it and shooting at goal. This is why defenders will often try to keep the puck out of the slot.
The Slot (film) is a 1985 American comedy film directed by John Landis and starring Chevy Chase as Clark Griswold, who goes on a gambling spree while vacationing in Las Vegas. The movie is based on the novel of the same name by Richard Matheson.
In a slot machine, the probability of a winning combination of symbols on each reel is determined by the paytable. Depending on the game, the payouts can vary from one coin to many coins for the same symbol. The number of coins played per spin also affects the probability of winning. If a player plays fewer coins, his or her chances of winning are greater, but the total payout is lower.
In Qt, signals and slots are a powerful component programming mechanism. Signals are public access functions that can be emitted from any class, while slots are macros that can be defined for a specific purpose. Together they provide a framework for inter-class communication. The rules for using slots are the same as for connecting signals: a signal must not have more arguments than the signature passed to the SLOT() macro.
