In this article we will see how we user entered item get added after the current selected position in the combo box i.e when user insert item in the editable combo box it get inserted at the position at which is after current selected item is in the drop down list, by default when user insert any item it get inserted at the bottom.
Note : When item get inserted it will not replace or overwrite the item which was that before although it will shift the position of other items to get added at the desired position.
In order to make combo box such that item inserted by user get added after the selected position 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 after the current
4. Create label
5. Retrieve the insertion policy and show it with the help of label
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" ]
# 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
# new item will get added after the selected place
self .combo_box.setInsertPolicy(QComboBox.InsertAfterCurrent)
# 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 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
