PyQt5 QCommandLinkButton – 获取图形效果

在本文中，我们将了解如何为 QCommandLinkButton 设置图形效果。图形效果可以是阴影、模糊或颜色效果，这些效果可以随时更改，也可以随时创建新效果。如果此命令链接按钮上已经安装了效果， QWidget会在安装新效果之前删除现有效果。图形效果可以通过setGraphicsEffect方法设置到命令链接按钮。

为了做到这一点，我们使用graphicsEffect方法和命令链接按钮对象

Syntax : button.graphicsEffect()

Argument : It takes no argument

Return : It returns QGraphicEffect object

编程需要懂一点英语

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, 500, 400)
  
        # calling method
        self.UiComponents()
  
        # showing all the widgets
        self.show()
  
    # method for components
    def UiComponents(self):
  
        # creating a command link button
        cl_button = QCommandLinkButton("Press", self)
  
        # setting geometry
        cl_button.setGeometry(250, 100, 200, 50)
  
        # shadow effect
        effect = QGraphicsDropShadowEffect()
        effect.setOffset(20, 20)
  
        # setting effect to the command link button
        cl_button.setGraphicsEffect(effect)
  
        # creating label
        label = QLabel("GeeksforGeeks", self)
  
        # setting label geometry
        label.setGeometry(50, 100, 200, 80)
  
        # making label multiline
        label.setWordWrap(True)
  
        # getting graphic effect
        value = cl_button.graphicsEffect()
  
        # setting text to the label
        label.setText("Effect : " + str(value))
  
  
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())

输出：
