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 ())
