近来用Qt编写一段多线程的TcpSocket通信程序,被其中Qt中报的几个warning搞晕了,一会儿是说“Cannot create children for a parent that is in a different thread”,有时候又是“QSocketNotifier: socket notifiers cannot be enabled from another thread”,还经常又Assert failure:Cannot send events toobjects owned...
ASSERTfailureinQCoreApplication:"there should be only one application object" 点击"忽略警告,继续执行",发现程序还是可以”正常“运行的。既然官方警告,单个进程中只允许有一个QCoreApplication,那么为什么不把QCoreApplication设计成单例模式呢?这是因为QCoreApplication有子孙类QGuiApplication和QApplication,而如果把...
