PyQt5 – Setting line edit to the ComboBox

In this article we will see how we can set line edit to the combo box, line edit is the widget in pyqt5. A line edit allows the user to enter and edit a single line of plain text with a useful collection of editing functions, including undo and redo, cut and paste, and drag and drop. In order to add line edit to the combo box we use setLineEdit method, with this we can use line edit widget to enter the item in combo box even if it non editable state.

Syntax : combo_box.setLineEdit(line_edit) 

Argument : It takes QLineEdit object as argument 

Action performed : This will add line edit to the combo box

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 = ["Sayian", "Super Sayian", "Super Sayian 2"]

        # 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)

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

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

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

Output :
