PyQt5标签 – 检查阴影是否被启用

在这篇文章中，我们将看到如何检查标签的阴影是否被启用。在setEnabled方法的帮助下，阴影可以被启用或禁用。

为了做到这一点，我们使用isEnabled方法

语法： shadow.isEnabled()

参数： 它不需要参数

返回： 它返回bool

以下是实现方法

# 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 label
        label = QLabel("Label", self)
 
        # setting alignment
        label.setAlignment(Qt.AlignCenter)
 
        # setting geometry to the label
        label.setGeometry(200, 100, 150, 60)
 
        # setting border
        label.setStyleSheet("border : 8px solid black")
 
        # creating a QGraphicsDropShadowEffect object
        self.shadow = QGraphicsDropShadowEffect()
 
        # setting blur radius
        self.shadow.setBlurRadius(30)
 
        # setting offset
        self.shadow.setOffset(10)
 
        # adding shadow to the label
        label.setGraphicsEffect(self.shadow)
 
        # checking if shadow is enabled or not
        check = self.shadow.isEnabled()
 
        # making label
        result = QLabel(self)
 
        # setting geometry
        result.setGeometry(200, 200, 300, 30)
 
        # setting text
        result.setText("Shadow enabled ? : " + str(check))
         
         
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())

输出 :
