PyQt5 标签 - 访问颜色效果的颜色

在本文中，我们将看到如何访问标签的颜色效果默认情况下标签没有颜色效果，尽管我们可以为标签创建颜色效果。颜色效果不像背景颜色，它更像是我们在图片上使用的彩色滤镜。

Syntax : color_effect.color()
Here color_effect is the QGraphicsColorizeEffect object

Argument : It takes no argument

Return : It returns QColor object

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__()
  
        # making background color light yellow
        self.setStyleSheet("background : lightyellow;")
  
        # 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)
  
        # creating a color effect
        color_effect = QGraphicsColorizeEffect()
  
        # setting color to color effect
        color_effect.setColor(Qt.darkGreen)
  
        # adding color effect to the label
        label.setGraphicsEffect(color_effect)
  
        # creating result label
        result = QLabel(self)
  
        # setting geometry to the result
        result.setGeometry(200, 200, 300, 30)
  
        # getting the color
        color = color_effect.color()
  
        # setting text to result label
        result.setText("Color : " + str(color))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
