What Is a Slot?

Slot

A slot is a narrow opening that receives a piece. Slots are also used for receiving signals. To connect a signal with a slot, you use the QObject::connect() method. This function is slightly slower than calling a receiver directly. However, it offers much less overhead. It can be used with function pointers and function arguments.

Slots are also used to manage air traffic at busy airports. For example, they are used to prevent repeated delays.

Some companies rely on slot-based scheduling to help their teams get important work done on time. These schedules can help workers prioritize tasks, organize workflow, and set deadlines. They can also be used by professionals to allocate resources.

Slots can be used to generate a list of possible outcomes and to track positive ones. They can also be used to plan and organize meetings, presentations, and consultations. Their use in these settings encourages open communication and collaboration.

The word “slot” comes from the Icelandic sl?? and the English sleuth. From there, it can mean “a keyway in machinery”, “a hollow at the base of the throat above the breastbone”, or a place for cutting or perforating something.

In the VLIW world, slots are common. They are often called by a component, and follow the normal C++ rules. But a slot does not know if its a signal. If you are expecting a signal and are not connected to the slot, it will report a runtime error.
