PyQt5 - 复选框中未选中指示器的背景图像

在本文中,我们将看到如何将背景图像设置为未选中复选框的指示器。默认情况下,指示器没有设置背景图像。

为了将背景图像设置为仅用于未选中状态的指示器,我们必须更改未选中状态指示器的样式表。下面是样式表代码。

QCheckBox::indicator:unchecked
{
background-image : url(image.png);
}

下面是实现。

# 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 geometry of check box
        checkbox.setGeometry(200, 150, 100, 60)
  
        # changing size of indicator
        # adding background image to the indicator
        # when it is in unchecked state
        checkbox.setStyleSheet("QCheckBox::indicator"
                               "{"
                               "width : 60px;"
                               "height : 60px;"
                               "}"
                               "QCheckBox::indicator:unchecked"
                               "{"
                               "background-image : url(indicator_image.png);"
                               "width : 60px;"
                               "height : 60px;"
                               "}")
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
