My main widget will launch qthread processes and each connected with the same slot. Upon the thread finishes, it will emit a signal and call the slot. My question is: what if multiple threads call the same slot nearly at the same time that the first call has not finished yet? Will the call queued? Will it automatically dropped if busy? Or it just do at the same time without considering any concurrency? (In this case, I guess I need to put a qmutex to hold the slot). I am worry if it's going to automatically be dropped.
Thanks for your comments.
