Qt QEventLoop: Event Loop Management in C++

QEventLoop is a class in the Qt framework that provides a way to create an event loop in a Qt application. An event loop is a mechanism that listens for events and responds to them. When an event occurs, the event loop dispatches it to the appropriate event handler. QEventLoop is used to block the execution of a thread until a specific event occurs. This can be useful in situations where you need to wait for a certain event to occur before proceeding with the execution of your application. For example, you might use a QEventLoop to wait for a network request to complete before updating the user interface.
