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 ())
