VNC QT Widget for Python using PyQt5

VNC Widget for Python using PyQt5

NOTE: This project is pretty much still in WiP status and I am struggling with the PIXEL_FORMAT.
So if someone knows a way to fix it or a better way of doing it in the first place, I would be happy about PRs ;)

How to install

pip3 install qvncwidget

TODO:

• Proper error handling onFatalError
• support for more than just RAW and RGB32 PIXEL_FORMATs
• support for compression
• implement rfb 3.7 and 3.8
• implement local and remote clipboard

Examples (see /examples folder)

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from qvncwidget import QVNCWidget

class Window(QMainWindow):
    def __init__(self):
        super(Window, self).__init__()

        self.initUI()

    def initUI(self):
        self.setWindowTitle("QVNCWidget")

        self.vnc = QVNCWidget(
            parent=self,
            host="127.0.0.1", port=5900,
            password="1234"
        )
        self.setCentralWidget(self.vnc)
        self.vnc.start()

app = QApplication(sys.argv)
window = Window()
#window.setFixedSize(800, 600)
window.resize(800, 600)
window.show()

sys.exit(app.exec_())

Example with key input (since 0.2.0)

import sys

from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtGui import QKeyEvent
from qvncwidget import QVNCWidget

class Window(QMainWindow):
    def __init__(self, app: QApplication):
        super(Window, self).__init__()

        self.app = app
        self.initUI()

    def initUI(self):
        self.setWindowTitle("QVNCWidget")

        self.vnc = QVNCWidget(
            parent=self,
            host="127.0.0.1", port=5900,
            password="1234"
        )
        self.setCentralWidget(self.vnc)
        self.vnc.start()

    def keyPressEvent(self, ev: QKeyEvent):
        self.vnc.onKeyPress.emit(ev)

    def keyReleaseEvent(self, ev: QKeyEvent):
        self.vnc.onKeyRelease.emit(ev)

app = QApplication(sys.argv)
window = Window(app)
window.resize(800, 600)
window.show()

sys.exit(app.exec_())

Example with key input and mouse tracking (since 0.2.3)

import sys

from PyQt5.QtWidgets import QApplication, QMainWindow
from PyQt5.QtGui import QKeyEvent
from qvncwidget import QVNCWidget

class Window(QMainWindow):
    def __init__(self, app: QApplication):
        super(Window, self).__init__()

        self.app = app
        self.initUI()

    def initUI(self):
        self.setWindowTitle("QVNCWidget")

        self.vnc = QVNCWidget(
            parent=self,
            host="127.0.0.1", port=5900,
            password="1234",
            mouseTracking=True
        )
        self.setCentralWidget(self.vnc)
        self.vnc.onInitialResize.connect(self.resize)
        self.vnc.start()

    def keyPressEvent(self, ev: QKeyEvent):
        self.vnc.onKeyPress.emit(ev)

    def keyReleaseEvent(self, ev: QKeyEvent):
        self.vnc.onKeyRelease.emit(ev)

app = QApplication(sys.argv)
window = Window(app)
window.resize(800, 600)
window.show()

sys.exit(app.exec_())
