Previously, we shared a … Read more
Below is a complete example of implementing communication between Qt C++ and Python using shared memory. This example consists of two parts: a Qt C++ application as the writer and a Python script as the reader. Qt C++ Writer (SharedMemoryWriter) // main.cpp#include <QCoreApplication>#include <QSharedMemory>#include <QBuffer>#include <QDataStream>#include <QDebug>#include <QThread> int main(int argc, char *argv[]){ QCoreApplication a(argc, … Read more
