The normal approach is to create the event on the stack, for example: QMouseEvent event(QEvent::MouseButtonPress, pos, 0, 0, 0); QApplication::sendEvent(mainWindow, &event); See also postEvent() and notify(). v
//segmentfault.com/u/killll_s 0 如图是我在我的Pyqt5工程中定义的一个调试按钮,当路径存在中文或者某些特殊字符时,尝试单击打开这个文件夹时控制台会提示ShellExecute failed(error 2)但如果是英文路径,则一切正常。请问我该如何解决这个问题? https://segmentfault.com/q/1010000042795580 2022-11-12...

Qt works around this by making exec() return main thread control to the browser, while preserving the stack. From the point of view of application code, the exec() function is entered and event processing happens as usual. However, the exec() call never returns, also not on application ex...
This function can only be called before the thread is started. Warning: Most operating systems place minimum and maximum limits on thread stack sizes. The thread will fail to start if the stack size is outside these limits. See also stackSize(). [static protected] void QThread::setTerminati...
An exception that is not caught in the function that has locked the mutex has no way of unlocking the mutex before the exception is passed up the stack to the calling function. QMutexLocker also provides a mutex() member function that returns the mutex on which the QMutexLocker is ...
The event is not deleted when the event has been sent. The normal approach is to create the event on the stack, for example:QMouseEvent event(QEvent::MouseButtonPress, pos, 0, 0); QApplication::sendEvent(mainWindow, &event);See also postEvent() and notify()....
