Most Qt methods aren't thread safe because there is always a performance penalty when using mutexes. - It isn't always possible to lock and unlock a mutex in a method. Sometimes - the need to lock spans several calls. For example, modifying a container - with an iterator requires a sequence of several calls which should not be - interrupted by other threads. In such a scenario, locking can be achieved - with a mutex that is kept outside of the object to be manipulated. With an - external mutex, the duration of locking can be adjusted to the needs of the - operation. One disadvantage is that external mutexes aid locking, but do - not enforce it because users of the object may forget to use it. - \section2 Dealing with Asynchronous Execution One way to obtain a worker thread's result is by waiting for the thread |
