Setting reserved width of text in a line of QListWidget
Question:
This is what i tried to do:
import PyQt5
import sys
from PyQt5 import QtWidgets
from testing import Ui_MainWindow
class App(QtWidgets.QMainWindow):
def __init__(self):
super(App,self).__init__()
self.ui=Ui_MainWindow()
self.ui.setupUi(self)
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"25":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"30":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"150":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"70":<10}')
self.ui.listWidget.addItem(f'{"Burger":<50}{"1":<20}{"25":<10}')
self.ui.listWidget.addItem(f'{"Waffle":<50}{"1":<20}{"30":<10}')
self.ui.listWidget.addItem(f'{"Coffee":<50}{"1":<20}{"150":<10}')
self.ui.listWidget.addItem(f'{"Coke":<50}{"1":<20}{"70":<10}')
print(f'{"Burger":<50}{"1":<20}{"25":<10}')
print(f'{"Waffle":<50}{"1":<20}{"25":<10}')
print(f'{"Coffee":<50}{"1":<20}{"25":<10}')
print(f'{"Coke":<50}{"1":<20}{"25":<10}')
app=QtWidgets.QApplication(sys.argv)

i put print functions to check whether my approaching is mistaken this is my output when i print those strings with reserved widths:
a screenshot my ui and how the strings look like
As you notice string fits to the row as i want when i leave the name column empty as shown below:
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"25":<10}')
But when i try to replace blank with the actual string as shown below:
self.ui.listWidget.addItem(f'{"Burger":<50}{"1":<20}{"25":<10}')
it doesn’t look exactly like i want.
All the helps are appreciated. Let me know if it is a duplicate.
Answers:
Based on your screenshot, it seems that you are trying to build a table using a list. Whilst it is certainly possible, it would feel more natural to use a table view or widget instead.
You could replace your QListWidget with QTableWidget. Then, you could insert new rows using insertRow. Or just initialise the table widget like this:
self.tableWidget = QTableWidget(10, 5, this);
And you could set the items like this:
self.tableWidget.setItem(row, column, QTableWidgetItem("foo"))
This is what i tried to do:

from testing import Ui_MainWindow
class App(QtWidgets.QMainWindow):
def __init__(self):
super(App,self).__init__()
self.ui=Ui_MainWindow()
self.ui.setupUi(self)
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"25":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"30":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"150":<10}')
self.ui.listWidget.addItem(f'{" ":<50}{"1":<20}{"70":<10}')
self.ui.listWidget.addItem(f'{"Burger":<50}{"1":<20}{"25":<10}')
self.ui.listWidget.addItem(f'{"Waffle":<50}{"1":<20}{"30":<10}')
