Hi

How can I set the value of the textedit box and slider of ui with the value from a config file when it has been created meaning if a configuration file exists then set the UI with value from the config file otherwise load ui with nothing set to any value.

ui.py

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow, QSlider, QLineEdit, QPushButton
from PyQt5.QtCore import Qt
import myconfig
config=myconfig.Config()
import os
import configparser

class Example(QMainWindow):

    def __init__(self):
        super().__init__()

        self.textbox = QLineEdit(self)
        self.textbox.move(20, 25)
        self.textbox.resize(60,30)

        button = QPushButton('Button', self)
        button.setToolTip('This is an example button')
        button.clicked.connect(self.printValue)
        button.move(100,25)

        self.mySlider = QSlider(Qt.Horizontal, self)
        self.mySlider.setGeometry(30, 140, 200, 30)
        self.mySlider.setMinimum(0)
        self.mySlider.setMaximum(100)

        # self.textbox.setText(str(config.getminValue()))
        # textboxValue = self.textbox.text()
        # self.mySlider.setValue(int(textboxValue) + 30)
       
        self.setGeometry(50,50,320,200)
        self.setWindowTitle("Checkbox Example")
        self.show()

    #def changeValue(self, value):
        #print(value)

    def printValue(self):
        if not os.path.exists('445nm.ini'):
            textboxValue = self.textbox.text()
            print(textboxValue) 
            f = open('445nm.ini', 'w+')
            config = configparser.RawConfigParser()
            config.add_section('445nm')
            config.set('445nm', 'intensity', textboxValue)
            config.write(f)            
            if self.textbox.text() == "":
                self.mySlider.setValue(0)            
            else:
                self.mySlider.setValue(int(textboxValue))
        else:
            self.mySlider.setValue(config.get('445nm', 'intensity'))
    
            # if self.textbox.text() == "":
            #     self.mySlider.setValue(0)
            # else:
            #     self.mySlider.setValue(config.get('445nm', 'intensity'))

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

config.py

[445nm]
intensity = 4

Hi,

What exactly is your issue currently ?

@Denni-0 I am not so sure as except for the "ui" word there's nothing that looks Designer related in the code @sdf1444 posted.
