166 \inmodule QtCore-
167 \brief The QThread class provides a platform-independent way to-
168 manage threads.-
169-
170 \ingroup thread-
171-
172 A QThread object manages one thread of control within the-
173 program. QThreads begin executing in run(). By default, run() starts the-
174 event loop by calling exec() and runs a Qt event loop inside the thread.-
175-
176 You can use worker objects by moving them to the thread using-
177 QObject::moveToThread().-
178-
179 \snippet code/src_corelib_thread_qthread.cpp worker-
180-
181 The code inside the Worker's slot would then execute in a-
182 separate thread. However, you are free to connect the-
183 Worker's slots to any signal, from any object, in any thread. It-
184 is safe to connect signals and slots across different threads,-
185 thanks to a mechanism called \l{Qt::QueuedConnection}{queued-
186 connections}.-
187-
188 Another way to make code run in a separate thread, is to subclass QThread-
189 and reimplement run(). For example:-
190-
191 \snippet code/src_corelib_thread_qthread.cpp reimpl-run-
192-
193 In that example, the thread will exit after the run function has returned.-
194 There will not be any event loop running in the thread unless you call-
195 exec().-
196-
197 It is important to remember that a QThread instance \l{QObject#Thread-
198 Affinity}{lives in} the old thread that instantiated it, not in the-
199 new thread that calls run(). This means that all of QThread's queued-
200 slots will execute in the old thread. Thus, a developer who wishes to-
201 invoke slots in the new thread must use the worker-object approach; new-
202 slots should not be implemented directly into a subclassed QThread.-
203-
204 When subclassing QThread, keep in mind that the constructor executes in-
205 the old thread while run() executes in the new thread. If a member-
206 variable is accessed from both functions, then the variable is accessed-
207 from two different threads. Check that it is safe to do so.-
208-
209 \note Care must be taken when interacting with objects across different-
210 threads. See \l{Synchronizing Threads} for details.-
211-
212 \section1 Managing Threads-
213-
214 QThread will notifiy you via a signal when the thread is-
215 started() and finished(), or you can use isFinished() and-
216 isRunning() to query the state of the thread.-
217-
218 You can stop the thread by calling exit() or quit(). In extreme-
219 cases, you may want to forcibly terminate() an executing thread.-
220 However, doing so is dangerous and discouraged. Please read the-
221 documentation for terminate() and setTerminationEnabled() for-
222 detailed information.-
223-
224 From Qt 4.8 onwards, it is possible to deallocate objects that-
225 live in a thread that has just ended, by connecting the-
226 finished() signal to QObject::deleteLater().-
227-
228 Use wait() to block the calling thread, until the other thread-
229 has finished execution (or until a specified time has passed).-
230-
231 QThread also provides static, platform independent sleep-
232 functions: sleep(), msleep(), and usleep() allow full second,-
233 millisecond, and microsecond resolution respectively. These-
234 functions were made public in Qt 5.0.-
235-
236 \note wait() and the sleep() functions should be unnecessary in-
237 general, since Qt is an event-driven framework. Instead of-
238 wait(), consider listening for the finished() signal. Instead of-
239 the sleep() functions, consider using QTimer.-
240-
241 The static functions currentThreadId() and currentThread() return-
242 identifiers for the currently executing thread. The former-
243 returns a platform specific ID for the thread; the latter returns-
244 a QThread pointer.-
245-
246 To choose the name that your thread will be given (as identified-
247 by the command \c{ps -L} on Linux, for example), you can call-
248 \l{QObject::setObjectName()}{setObjectName()} before starting the thread.-
249 If you don't call \l{QObject::setObjectName()}{setObjectName()},-
250 the name given to your thread will be the class name of the runtime-
251 type of your thread object (for example, \c "RenderThread" in the case of the-
252 \l{Mandelbrot Example}, as that is the name of the QThread subclass).-
253 Note that this is currently not available with release builds on Windows.-
