PyQt5 – How to Set skin to indeterminate indicator of Check box

  • Last Updated : 22 Apr, 2020

In this article we will see how to set skin to the checkbox when it is in indeterminate state. By default a black box symbol is placed for the indeterminate indicator although we can change it in-place of image. Skin is basically background image which can adjust it self according to the size of indicator of check box.

In order to do this we have to change the style sheet code, below is the style sheet code.

QCheckBox::indicator::indeterminate
{
border-image : url(image.png)
}

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
        checkbox1 = QCheckBox('Geek ?', self)
  
        # setting tristate check box
        checkbox1.setTristate(True)
  
        # setting geometry of check box
        checkbox1.setGeometry(200, 150, 100, 40)
  
        # changing style sheet code of check box
        # adding skin to indeterminate indicator
        checkbox1.setStyleSheet("QCheckBox::indicator:indeterminate"
                                "{"
                                "border-image : url(image.png);"
                                "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
