In this article, we will see how we user can add items in the combo box at the beginning i.e when user insert item in the editable combo box it get inserted at the top of the drop down list, by default when user insert any item it get inserted at the bottom.
In order to make combo box such that item inserted by user get added at the top in the drop down list, we have to do the following –
1. Create a combo box
2. Make the combo box editable using setEditable method
3. Set insertion policy of combo box to insert at top
4. Create label
5. Retrieve the insertion policy and show it with the help of label
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, 120, 30) # geek list geek_list = ["Geek", "Geeky Geek"] # adding list of items to combo box self.combo_box.addItems(geek_list) # creating editable combo box self.combo_box.setEditable(True) # setting insertion policy # making insertion to store at top self.combo_box.setInsertPolicy(QComboBox.InsertAtTop) # 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, 100, 200, 30)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
