PyQt5 – 复选框的图像指示器

复选框基本上分为两个部分，一个是默认在左边的指示器，另一个是复选框本身，即标签部分，上面有文字。在这篇文章中，我们将看到如何为指示器设置图像。下面是普通的复选框指示器与有图像指示器的复选框的对比。

为了给指示器设置图像，我们必须改变复选框指示器的样式表。下面是用于复选框对象的样式表代码。

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

以下是实施情况。

# 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, 80)
 
        # setting stylesheet
        # adding background image to indicator of check box
        # and changing width and height of indicator
        checkbox.setStyleSheet("QCheckBox::indicator"
                               "{"
                               "background-image : url(image.png);"
                               "width :40px;"
                               "height : 40px;"
                               "}")
 
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 :
