When you create a Qt application, you are automatically given a few slots and signals. Slots are containers for your data, and signals are connections between slots.
You can create your own slots and signals by using the Qt Creator tool, or by using the C++11 standard library.
To connect slots and signals, you use the connect() function. The connect() function takes two arguments: a slot name and a signal name.
The slot name is the name of the slot that you want to connect to the signal, and the signal name is the name of the signal that you want to connect to the slot.
The connect() function returns a QSlot::connected signal. This signal is connected to the slot named in the slot argument, and it signals that the slot is now connected to the signal.
You can use this signal to do things like manipulate the state of the slot.
You can also use connect() to create chains of slots. A chain is a series of connected slots that are all linked together.
You can use chains to store data, or to communicate information between different parts of your application.
Finally, you can also disconnect slots and signals using disconnect() . disconnect() takes two arguments: a slot name and a signal name.
The slot name is the name of the slot that you want to disconnect from the signal, and the signal name is the name of the signal that you want to disconnect from the slot.
