qwebchannel.py

python3.6 port of qwebchannel.js client library

Requirements:

Javascript Websocket api like websocket client. In the example i have used https://pypi.python.org/pypi/websocket-client

First run Qt5 standalone websocket c++ example. http://doc.qt.io/qt-5/qtwebchannel-standalone-example.html

Then run "python3 path/of/qwebchannel.py"

Example code:

from qwebchannel import QWebchannel
import websocket
import threading

def receive_message_from_cpp(message):
    print("Received message: {}".format(message))

def data_send_from_python(channel):
    while True:
        inp = input("Enter message: ")
        channel.objects.dialog.receiveText(inp)

def channel_ready(channel):
    channel.objects.dialog.sendText.connect(receive_message_from_cpp)
    channel.objects.dialog.receiveText("Client connected, ready to send/receive messages!")
    thread = threading.Thread(target=data_send_from_python, args=(channel,))
    thread.setDaemon(True)
    thread.start()
def on_open(ws):
    print("Socket started")
    w = QWebchannel(ws,channel_ready)
ws = websocket.WebSocketApp("ws://127.0.0.1:12345")
ws.on_open = on_open
ws.run_forever()
