PyQt5 – How to get line edit of ComboBox

In this article we will see how we can get the line edit of combo box, line edit is basically a default object of combo box where we insert the text, it is used by the combo box to show the selected option and for getting the input, we can get the line edit object of the combo box with the help of setLineEdit method In order to get the delegate object of the combo box we will use lineEdit method

Syntax : combo_box.lineEdit() Argument : It takes no argument Return It returns QLineEdit object

Below is the implementation – 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys


class Window(QMainWindow):

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

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method
        self.UiComponents()

        # showing all the widgets
        self.show()

    # method for widgets
    def UiComponents(self):

        # creating a combo box widget
        self.combo_box = QComboBox(self)

        # setting geometry of combo box
        self.combo_box.setGeometry(200, 150, 150, 30)

        # geek list
        geek_list = ["Saiyan", "Super Saiyan", "Super Saiyan 2", "Super Saiyan B"]

        # adding list of items to combo box
        self.combo_box.addItems(geek_list)

        # creating a line edit
        edit = QLineEdit(self)

        # setting line edit
        self.combo_box.setLineEdit(edit)

        # getting line edit
        line = self.combo_box.lineEdit()

        # creating label to show delegate
        label = QLabel("Line edit = " + str(line), self)

        # setting geometry of the label
        label.setGeometry(150, 100, 350, 30)


# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
