PyQt5 QLabel - 添加模糊效果

在本文中,我们将看到如何为标签添加模糊效果,模糊意味着标签的平滑,默认情况下标签没有模糊效果,尽管我们可以随时添加模糊效果。下面是具有模糊效果的标签的表示。

句法 :

# creating a blur effect
self.blur_effect = QGraphicsBlurEffect()

# adding blur effect to the label
label.setGraphicsEffect(self.blur_effect)

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 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 geometry to the label
        label.setGeometry(200, 100, 150, 60)
  
        # setting alignment to the label
        label.setAlignment(Qt.AlignCenter)
  
        # setting font
        label.setFont(QFont('Arial', 15))
  
        # creating a blur effect
        self.blur_effect = QGraphicsBlurEffect()
  
        # adding blur effect to the label
        label.setGraphicsEffect(self.blur_effect)
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出 :
