[PyQt] Collect entry from textline Widget via UI file

[mart79]

Hi,

I would like to know how I can access a QLineEdit widget in a UI file directly from Python.
I have read some examples on the Internet but, I can't get it to work.

This is what I have:
original *.ui file: propertyDialog.ui
extracted *.py file: propertyDialog.py
QLineEdit widget name on the ui: "input_PipeName"

The script I have so far is:

from PyQt5 import QtCore, QtGui, QtWidgets
from propertyDialog import Ui_Dialog

class mainProgram(QtWidgets.QMainWindow, Ui_Dialog):
    def __init__(self, parent=None):
        self.cntPipe = 0
        self.cntLiner = 0
        self.cntCoating = 0
        self.pipeproperty = {}
        self.coating = {}
        self.liner = {}
        super(mainProgram, self).__init__(parent)
        # self.calc = Calculations()
        self.setupUi(self)
        self.response_AddPipe.clicked.connect(self.add_pipe)

    def add_pipe(self):
        self.cntPipe +=1
        self.cntLiner = 0
        self.cntCoating = 0
        self.pipeproperty[self.cntPipe]={}
        pipe_name = self.inputPipe_name.text()
        self.pipeproperty[self.cntPipe]["Name"] = pipe_name

if __name__ == "__main__":

    import sys
    app = QtWidgets.QApplication(sys.argv)
    nextGui = mainProgram()
    nextGui.show()
    sys.exit(app.exec_())

With the error:

Error:
"C:\Users\Usr\Desktop\Work Folder PPM\VirtualEnvironment\Scripts\python.exe" "C:/Users/Usr/Desktop/Work Folder PPM/VirtualEnvironment/Scripts/Total.py"
Traceback (most recent call last):
  File "C:/Users/Usr/Desktop/Work Folder PPM/VirtualEnvironment/Scripts/Total.py", line 151, in <module>
    nextGui = mainProgram()
  File "C:/Users/Usr/Desktop/Work Folder PPM/VirtualEnvironment/Scripts/Total.py", line 15, in __init__
    self.response_AddPipe.clicked.connect(self.add_pipe())
  File "C:/Users/Usr/Desktop/Work Folder PPM/VirtualEnvironment/Scripts/Total.py", line 23, in add_pipe
    pipe_name = self.inputPipe_name.text()
AttributeError: 'mainProgram' object has no attribute 'inputPipe_name'

Process finished with exit code 1

Can someone help me with this? It seems to fail on:

pipe_name = self.inputPipe_name.text()
