@Jalkhov said in Verify internet connection from QThread:
Ok, I have adapted the code, it would look like this?
from PyQt5.QtWidgets import QWidget, QPushButton, QApplication, QListWidget, QGridLayout, QLabel
from PyQt5.QtCore import QTimer, QDateTime, QThread, pyqtSignal
import requests
import sys
class CheckThread(QThread):
statusChanged = pyqtSignal(bool)
def run(self):
try:
request = requests.get("http://www.google.com", timeout=5)
self.statusChanged.emit(True)
except (requests.ConnectionError, requests.Timeout) as exception:
self.statusChanged.emit(False)
class WinForm(QWidget):
def __init__(self, parent=None):
super(WinForm, self).__init__(parent)
self.setWindowTitle('QTimer example')
self.listFile = QListWidget()
self.label = QLabel('Label')
self.startBtn = QPushButton('Start')
self.endBtn = QPushButton('Stop')
self.count = 0
layout = QGridLayout()
self.timer = QTimer()
self.timer.timeout.connect(self.showTime)
layout.addWidget(self.label, 0, 0, 1, 2)
layout.addWidget(self.startBtn, 1, 0)
layout.addWidget(self.endBtn, 1, 1)
# self.startBtn.clicked.connect(self.startTimer)
self.endBtn.clicked.connect(self.endTimer)
self.setLayout(layout)
self.check_thread = CheckThread()
self.check_thread.statusChanged.connect(self.handle_status_changed)
self.startBtn.clicked.connect(self.start_thread)
def start_thread(self):
self.start = True
self.timer.start(100)
self.startBtn.setEnabled(False)
self.endBtn.setEnabled(True)
def handle_status_changed(self, status):
print(status)
def showTime(self):
self.count += 1
time = self.count / 10
self.label.setText(str(time))
if time % 5 == 0:
self.check_thread.start()
def endTimer(self):
self.count = 0
self.timer.stop()
self.startBtn.setEnabled(True)
self.endBtn.setEnabled(False)
self.label.setText("0")
if __name__ == '__main__':
app = QApplication(sys.argv)
form = WinForm()
form.show()
sys.exit(app.exec_())
I placed
self.check_thread.start()
inside the showtime function because that way it is shown at the time interval indicated by the if, I don't know if it is right like that.
