Is there no waitforsingleobject in Qt?

In Qt, there is no direct function for waiting on a single object. Qt primarily uses an event loop to handle events and signals asynchronously instead of using blocking wait functions. In most cases, you can use the signal-slot mechanism or asynchronous operations to handle concurrent operations.

If you need to wait for a specific object to complete certain operations, you can consider using signals and slots mechanism or Qt’s asynchronous operations. By connecting the object’s signals and slots, you can trigger the corresponding slot function when the object completes the operation. Additionally, Qt also provides some asynchronous operation classes, such as QFuture and QFutureWatcher, for handling operations that need to be waited for.

If you must wait for an object or thread to complete using a blocking method, you can consider using Qt’s underlying interfaces QWaitCondition and QMutex to create your own waiting function. These classes offer functionality for waiting conditions and mutual exclusion locks, allowing you to implement wait operations similar to WaitForSingleObject.

In conclusion, while Qt does not directly provide a function for waiting on a single object, you can achieve similar functionality through signal and slot mechanisms, asynchronous operations, or by using lower-level interfaces such as QWaitCondition and QMutex.
