mylayout.addWidget(self.imageviewer, 1, 1)
You're not reading @SGaist's replies and understanding/acting on them. Anyway, what do you intend this line to do?

I call the above class each time the mouse pointer changes position. The problem is that nothing is shown..but the print commands that I have embed between the below commands work!
Why?
I call it like this:w = Town() w.show()
This is the class that I call
class Town(QWidget): def __init__(self): super().__init__() import sys from PyQt5.QtWidgets import QWidget,QPushButton,QApplication,QListWidget,QGridLayout,QLabel from PyQt5.QtCore import QTimer,QDateTime from PyQt5 import QtWidgets from PyQt5.QtWidgets import QApplication, QMainWindow from PyQt5 import QtCore win = QWidget() grid=QGridLayout() import pandas ct = pandas.read_csv('CurrentTown.csv') town = QLabel("town:") town.setStyleSheet("border: 1px solid black; background-color: yellow") grid.addWidget(town, 1,1) textEdit_1 = QLineEdit(ct) textEdit_1.setReadOnly(True) grid.addWidget(textEdit_1,1,2) import os os.remove('CurrentTown.csv') self.setLayout(grid) win.setGeometry(100,100,200,100) win.setWindowTitle("Test") win.show() win.update()

I call it like this:
Where?
Please show that part of your code.
Also, why do you create a new QWidget in Town which does not contain anything? Town is already a QWidget. -

win = QWidget() . . . win.setGeometry(100,100,200,100) win.setWindowTitle("Test") win.show() win.update()
So, class Town(QWidget): makes a widget before the previous code...(?)

Yes. Why do you need win?
All other widgets you create in Town are added to Town. -

All other widgets you create in Town are added to Town.And what I do with these?
win.setGeometry(100,100,200,100) win.setWindowTitle("Test") win.show() win.update()
I call them with self???

I don't know what you want to do with this.
You simply create a widget without parent and show it - it will be a stand-alone WINDOW."I call them with self???" - what does this mean? If you're asking me how you should change it: then I repeat my question "Why do you need it at all"?! Can you first answer this question?

I call the class (from another class) like this:
w = Town() w.show()
how could the Qwidget be displayed if I do not include these (?) :
win.setGeometry(100,100,200,100) win.setWindowTitle("Test") win.show() win.update()
Especially win.show
Update: I removed the above mentioned lines. I put a sleep method for 10 sec. The code opens a window but it does not have something inside...and looks like it "stucks".

@john_hobbyist I really have no idea what you want to do!
If you want to show Town all you need isw = Town() w.show()
So, once more: why do you need win? win is ANOTHER widget, it is not Town! If you refuse to answer this simple question I'm out of this thread.
"but it does not have something inside...and looks like it "stucks"." - this is also something I already told you: you are showing a widget (win) which has no parent, so it is shown as a window. And since win does not contain any other widgets it is an empty window. -
