PyQt5 – How know the insertion policy of the ComboBox
  • Last Updated : 22 Apr, 2020

In this article we will see how we can know the insertion policy of the combo box. By default it insert at the bottom although we can change it any time. Insertion policy tells where will the new item when inserted by the user will get stored.

In order know the insertion policy we use insertPolicy method.

Syntax : combo_box.insertPolicy()

Argument : It takes no argument

Return : It returns InsertPolicy object (prints 3 for insert at bottom)



Below is the implementation




# 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, 120, 30)
  
        # geek list
        geek_list = ["Geek", "Geeky Geek", "Legend Geek", "Ultra Legend Geek"]
  
        # adding list of items to combo box
        self.combo_box.addItems(geek_list)
  
        # creating editable combo box
        self.combo_box.setEditable(True)
  
        # getting current insertion policy
        policy = self.combo_box.insertPolicy()
  
        # creating label to  print the policy
        label = QLabel("Insertion policy = " + str(policy), self)
  
        # setting geometry of the label
        label.setGeometry(200, 200, 200, 30)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
