A slot is a grammatical element that has a specific function. It can be used to represent a specific morpheme sequence in a sentence. In other words, a slot is an assignment, job opening, or position. For example, a slot at a newspaper can be the position of the chief copy editor. In aviation, a slot is a designated area within an airport that is authorized by the air-traffic authority.
Subject
The subject of a sentence is usually the noun phrase that is the focus of the sentence. However, the subject is not always the most appropriate word to fill the slot. Rather, it may be a phrase or even a whole clause. It is important to note that the grammatical name of the word doesn’t necessarily determine its meaning. The main thing is to use the words that convey the most important information.

Object
The keyword slot is used to describe a placeholder that contains a value that is associated with a user-defined class. In Java, every instance has a copy of the slots specified by its immediate class or the ones obtained through inheritance. The number of slots is limited only by the available memory. The name of a slot can be a single character, a string, or a number. Generally, the keywords isa and name are reserved for object patterns.
Object’s type
A class or instance that has slot allocation can be used for shared values and object-based storage. The documentation for a slot’s location is exposed to the user whenever a class or instance is created or customized. In addition, a slot’s accessibility is defined by its generic function. This article provides a brief overview of the various types of slots available. This article also provides an example of how to use them in code.
Object’s function pointer
A class should return the object’s function pointer in a slot, rather than a virtual function. This is a problem when a class implements multiple inheritance and uses overloaded signals and slots. This causes some extra data to be generated and binaries to be relocated. To avoid this problem, you should call the class’s type_new() method from the class statement. You can also call QSlotObjectBase.
QObject::connect()
The QObject::connect() method creates a connection between two objects by emitting a signal. It is only available for member functions; it does not work for non-member functions or functors. A connection can be broken by calling QObject::disconnect(). It is a thread-safe operation. QObject::connect() returns a handle of the connection, which is a reference to the current object that is connected.
