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 ())
