PyQt5 – 为复选框的未选中指标设置皮肤

在这篇文章中，我们将看到如何在复选框处于未选中的状态时为其设置皮肤。默认情况下，虽然我们可以在图像中改变它，但没有为未选中的指示器放置任何符号。皮肤基本上是背景图像，它可以根据复选框的指示器的大小来调整自己。为了做到这一点，我们必须改变样式表代码，下面是样式表代码。

QCheckBox::indicator::unchecked
{
border-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
        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 unchecked indicator
        checkbox1.setStyleSheet("QCheckBox::indicator:unchecked"
                                "{"
                                "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())
