Pyqt5 Notification from scratch - python-3.x

Question

I wanted a module programmed on PyQt5 that would make notifications appear on the right side of the screen, so i found a question here:
PyQt5 notification from QWidget
and i used this code with only a few changes, but the problem is, it creates a new window and does not show the QWidget on screen.
Here is the code
class Message(QWidget):
def __init__(self, title, message, parent=None):
QWidget.__init__(self, parent)
self.setLayout(QGridLayout())
self.titleLabel = QLabel(title, self)
self.titleLabel.setStyleSheet(
"font-family: 'Roboto', sans-serif; font-size: 14px; font-weight: bold; padding: 0;")
self.messageLabel = QLabel(message, self)
self.messageLabel.setStyleSheet(
"font-family: 'Roboto', sans-serif; font-size: 12px; font-weight: normal; padding: 0;")
self.buttonClose = QPushButton(self)
self.buttonClose.setIcon(QIcon("extra/close.png"))
self.buttonClose.setFixedSize(14, 14)
self.layout().addWidget(self.titleLabel, 0, 0)
self.layout().addWidget(self.messageLabel, 1, 0)
self.layout().addWidget(self.buttonClose, 0, 1, 2, 1)
class Notification(QWidget):
signNotifyClose = pyqtSignal(str)
def __init__(self, parent=None):
super(QWidget, self).__init__(parent)
self.setWindowFlags(Qt.FramelessWindowHint | Qt.WindowStaysOnTopHint)
resolution = QDesktopWidget().screenGeometry(-1)
screenWidth = resolution.width()
screenHeight = resolution.height()
self.nMessages = 0
self.mainLayout = QVBoxLayout(self)
self.move(screenWidth, 0)
def setNotify(self, title, message):
m = Message(title, message, self)
self.mainLayout.addWidget(m)
m.buttonClose.clicked.connect(self.onClicked)
self.nMessages += 1
self.setStyleSheet("background-color: black;")
self.show()
def onClicked(self):
self.mainLayout.removeWidget(self.sender().parent())
self.sender().parent().deleteLater()
self.nMessages -= 1
self.adjustSize()
if self.nMessages == 0:
self.close()
and this is the file importing the previous one:
from notifierP import *
import sys
class Example(QWidget):
counter = 0
def __init__(self, parent=None):
QWidget.__init__(self, parent)
self.setLayout(QVBoxLayout())
btn = QPushButton("Send Notify", self)
self.layout().addWidget(btn)
self.notification = Notification()
btn.clicked.connect(self.notify)
def notify(self):
self.counter += 1
print(self.counter)
self.notification.setNotify("Title{}".format(self.counter),
"message{}".format(self.counter))
if __name__ == '__main__':
app = QApplication(sys.argv)
w = Example()
w.show()
sys.exit(app.exec_())
My Question is, why does this happen, and how can i fix it?
How it is on my screen
This all it shows, nothing else.

Answer 1

okay the problem here was that the
self.move()
was moving the widget outside the screen, after i changed its possition to inside the screen it works perfectly.
