Samuel Bachorik

Hello guys, please i already made similar topic but in this one iam using classes and iam facing same problem... This code just dont work and i have NO idea why. Function setExpresion in main.py is executed but doesnt set text...

File main.py

from PyQt5 import QtWidgets
import sys
from PyQt5.QtWidgets import QMainWindow, QApplication, QLineEdit

class Window(QMainWindow):
   def __init__(self):
       super().__init__()
       self.textboxvalue2 = ""
       self.setWindowTitle("Samuel")
       self.setGeometry(200, 200, 259, 258)

       self.textbox = QLineEdit(self)
       self.textbox.move(5, 5)
       self.textbox.resize(188, 35)
       self.textbox.setText(str(self.textboxvalue2))
       self.textbox.setPlaceholderText("Enter numbers")
       self.textboxValue = self.textbox.text()

       self.b10 = QtWidgets.QPushButton(self)
       self.b10.setText("0")
       self.b10.move(68, 219)
       self.b10.resize(60, 35)
       self.b10.clicked.connect(self.clicked0)
       self.show()

   def setExpression(self,expression):
       print(expression) 
       self.textbox.setText(str(expression))

   def clicked0(self):
       import Buttons
       z = Buttons.Buttons()
       z.buttonOne()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = Window()
    sys.exit(app.exec())

File Buttons.py

class Buttons:

    def buttonOne(self):
        import main
        x = main.Window()
        x.setExpression("1")

Hi,

Same as before, you are creating a local variable that is short lived and has nothing to do with the instance you create in your main.py file.
