In this article we will see how we can allow duplicates insertions in the combo box. By default no duplicate insertion is allowed although programmatically inserting duplicate items into the combo box is possible but user can’t insert duplicate values.
In order to allow duplicates insertion we will use setDuplicatesEnabled
method
Syntax : combo_box.setDuplicatesEnabled(True)
Argument : It takes bool as argument
Action performed : It will allow user to make duplicate insertions
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)
# making it editable combo box
self .combo_box.setEditable( True )
# allowing duplication of items
# setting duplicates = True
self .combo_box.setDuplicatesEnabled( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
