In this article we will see how to create round indicator of check box. By default, check box have square indicator although with the help of style sheet we can change it make it round. Below is the representation of normal indicator vs the round indicator of check box.
In order to do this we have to do the following :
- Setting up the border to indicator as when we try to change the shape border will get vanish, so in order to deal with it we will provide custom border to it.
- Set the size of indicator and it should be in square shape.
- Set the border radius to sum of half of the length of indicator and the thickness of border i.e
radius = width/2 + thickness
Style sheet code –
QCheckBox::indicator { border : 2px solid black; width : 20px; height : 20px; border-radius : 22px; }
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 the check-box checkbox = QCheckBox( 'Geek ?' , self ) # setting tristate check box checkbox.setTristate( True ) # setting geometry of check box checkbox.setGeometry( 200 , 150 , 100 , 40 ) # adding border to the check box and padding # adding border to indicator and setting size # setting border radius checkbox.setStyleSheet( "QCheckBox" "{" "border : 2px solid clack;" "padding : 5px;" "}" "QCheckBox::indicator" "{" "border : 2px solid black;" "width : 20px;" "height : 20px;" "border-radius :12px;" "}" ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
Output :
