PyQt5 – Increase size of separator in between the item of ComboBox

  • Last Updated : 20 Jun, 2021

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 he 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 – 
 

Python3




# 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 Saiyan", "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())

Output :
