问题 I want to run command with PyQt5. And I want to get the stdout and stderr in time order and in real-time. I separated into UI class and Worker class. There are several UI classes, but for simplicity, I've specified just one. I've tried to solve this problem, but I can't. I can't connect between the Worker thread and logger function. test_ui.py import sys import subprocess from PyQt5.QtWidgets import QApplication, QWidget, QHBoxLayout, QVBoxLayout from PyQt5.QtWidgets import QPushButton,

问题 I'm trying to run an external exe from my Qt app. It's an "autorun application" and it has three buttons: one is suppose to run an external installer which is an .exe app. I tried: system("Setup.exe") It works but it displays terminal when running the installer. I also tried: QProcess::startDetached("Setup.exe"); and also tried: QProcess *process = new QProcess(this); process->start("Setup.exe"); but neither works (nothing happens, there are no logs in the console output as well). Can someone

问题 I am trying to execute a command line using QProcess as soon as I push a QPushButton on my gui. The problem I have is that the .sh executable file is never executed. The script I am trying to execute is very simple and reported below: #!/bin/bash echo "try one two three" rostopic echo -b LaserScan_PointCloud2_test.bag -p /scan > laserScan_test_1.csv Below the function that activate the button: filterpcdinterface.h private slots: void on_executeScriptBtn_clicked(); private: QProcess

问题 I'm using Qt in order to implement an interface allowing to develop for embedded system. I'm facing a problem: In order to flash program into the embeded system I use QProcess, in order to use the command "make" and "make flash". To make there isn't any problem and the program compiles successfully. But when I try to do the same thing for "make flash" there is a problem because the console is waiting for user input, he has to press a button on the embedded system. But QProcess returns
