PyQt5 – Increase size of separator in between the item of ComboBox
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 –
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 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 ()) |
Output :
