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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
