5. 将 MyWork 对象移动到创建的子线程对象中,需要调用 QObject 类提供的moveToThread() 方法 // void QObject::moveToThread(QThread *targetThread);// 如果给work指定了父对象, 这个函数调用就失败了// 提示: QObject::moveToThread: Cannot move objects with a parentwork->moveToThread(t1);// 移动...
loadAcquire() == targetThread) { // object is already in this thread return; } // 不能移动一个有父对象的对象 if (d->parent != nullptr) { qWarning("QObject::moveToThread: Cannot move objects with a parent"); return; } // 窗口部件不能移动到一个新的线程,在Qt里GUI操作只能在主...

moveToThread位于QObject中,官方对此函数的解释如下: void QObject::moveToThread(QThread *targetThread) Changes the thread affinity for this object and its children. The object cannot be moved if it has a parent. Event processing will continue in the targetThread. ...

Qt5中两种线程操作的方法 1. 通过创建QTread子实现run()函数来实现 QThread::run()是线程的入口 相当于 main函数一样 创建的线程通过调用start()来执行run(); run() 是一个虚函数 通过子类实现方法通过moveToThread()函数来实现作用:将某一个对象从当前的线程中推到另一
1.多线程中出现QObject: Cannot create children for a parent that is in a different thread 这个错误提示的实际意思是,不能在子线程中生成跨线程调用的成员。如果一个成员在父线程中被直接调用了,那么这个成员必须处在父线程中,强行在子线程中生成就会出现这个错误提示。 将在多线程中构造函数中new出来的变量,...
