execute ping command with GUI

Question

While writing a GUI application in PyQt5 I encounter weird(for me) behavior. When I wanted to open an information window and start doing another thing after it fully loads.

Answer 1

As an option. Try it:

import sys
import os
from PyQt5.QtWidgets import QApplication,QMessageBox
from PyQt5.QtCore import QTimer

app = QApplication(sys.argv)

box = QMessageBox()
box.setText("Text")
box.show()

def osSystem():
    os.system("ping 8.8.8.8 ") 

QTimer.singleShot(20, osSystem )

#os.system("ping 8.8.8.8 ")


sys.exit(app.exec())
