In this article we will see how we can increase the size of separator at the desired index in the combo box. By default there is no separator. Separator is the black line in between two items, in order to add the separator we use insertSeparator method. Below is representation of how combo box items with a separator looks like –
In order to increase the size of separator we have to use the insertSeparator method multiple time with the index value equal to desired index or greater than that this will increase the size of separator of given index.
Syntax :
combo_box.insertSeparator(index)
combo_box.insertSeparator(index)
Argument : It takes integer as argument i.e index
Action performed : It will add separator at the given index and using same statement with same index will increase the size of separator
Note : Index value must be greater or equal to the desired index.
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 , 150 , 30 )
# geek list
geek_list = [ "Sayian" , "Super Sayian" , "Super Sayian 2" , "Super Sayian B" ]
# adding list of items to combo box
self .combo_box.addItems(geek_list)
# index
index = 3
# adding separator at given index
self .combo_box.insertSeparator(index)
# increasing the size of separator
self .combo_box.insertSeparator(index)
self .combo_box.insertSeparator(index)
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
