“qt qthread: destroyed while thread is still running” 这条错误信息表明,在 Qt 应用程序中,一个 QThread 对象在其关联的线程仍在运行时被销毁了。这是不允许的,因为 QThread 管理着线程的生命周期,如果 QThread 对象被销毁,那么它所管理的线程可能无法正确终止,从而导致资源泄露或程序崩溃。 2. 可能原因 ...
简介:在Qt中,当一个线程还在运行时,如果尝试销毁这个线程的QThread对象,就会导致QThread: Destroyed while thread is still running的错误。为了避免这个错误,我们需要确保线程在结束之前不销毁QThread对象。以下是一些解决这个问题的常见方法。 文心大模型4.5及X1 正式发布 百度智能云千帆全面支持文心大模型4.5 API调用,...
QThread: Destroyed while thread is still running 原因:python中线程不能是临时变量, 错误代码: forcamincams:mdcall_thread=Multi_dllcall_q()mdcall_thread.param(cv_dll,cam[0],cam[1],cam[2],cam[3])mdcall_thread.start()whileTrue:pass ...
【摘要】 详解qthread destroyed while thread is still running在 Qt 编程中,我们经常使用 QThread 类来创建多线程应用程序。但在使用 QThread 时,有时会遇到这样的报错信息:QThread: Destroyed while thread is still running。这个错误表示在销毁 QThread 对象时,线程仍然在运行。 造成这个... ...
runThread->start(),开启线程。 **在当前线程的析构函数中,如果先删除runThread再删除m_MyClass,则会出现错误QThread: Destroyed while thread is still running **正确的写法应该是: runThread->exit(0); delete m_MyClass; delete runThread; --- 作者:爱因...
PyQt5在执行多线程的时候遇到:QThread:Destroyed while thread is still running 错误分析: QThread的子线程还在运行但是线程就被销毁了,导致程序闪崩,该错误是笔者用终端执行py文件时提示的。 解决方法: 方法一: 子线程是在后台不断的检测PC连接的设备,当检测到合适的设备连接成功后,主线程进行逻辑处理,此时子线程...
1 创建线程:2 线程实现:3 关闭程序,提示:QThread: Destroyed while thread is still running 在创建线程类的析构函数中加入wait,等待线程结束
QThread: Destroyed while thread is still running Qt5已经分装了函数 voidQThread::requestInterruption() { Q_D(QThread); QMutexLocker locker(&d->mutex);if(!d->running || d->finished || d->isInFinish)return;if(this==QCoreApplicationPrivate::theMainThread) {...
