PyQt5 标签 – 设置阴影的偏移量

在本文中,我们将看到如何将偏移量设置为标签的阴影,偏移量基本上是标签阴影与标签之间的距离,默认偏移值为 8,尽管我们可以随时更改它。

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 background color of window
        # self.setStyleSheet("background-color : black;")
  
        # 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
        shadow = QGraphicsDropShadowEffect()
  
        # setting blur radius
        shadow.setBlurRadius(20)
  
        # setting offset
        shadow.setOffset(100)
  
        # adding shadow to the label
        label.setGraphicsEffect(shadow)
  
          
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
