PyQt5 – 设置未选中的复选框指标在悬停时的背景图片

PyQt5 – 设置未选中的复选框指标在悬停时的背景图片

在这篇文章中,我们将看到如何为复选框的指示器设置背景图片,当它处于未选中状态和鼠标悬停时。为了做到这一点,我们必须改变复选框中未选中状态和鼠标移动到它上面时的指示器的样式表。

下面是样式表的代码。

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