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)
win=App()
win.show()
app.exec()

if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

i put print functions to check whether my approaching is mistaken this is my output when i print those strings with reserved widths:

Output of print functions

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.

CodePudding user response:

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"))
