In this article we will see how we can access the strength of the color effect of the label by default there is no color effect to the label although we can create color effect for the label. Color effect is not like background color it is more like of colored filters we use on pictures. Strength is the intensity of the color effect.
In order to do this we use strength method.
Syntax : color_effect.strength()
Here color_effect is the QGraphicsColorizeEffect objectArgument : It takes no argument
Return : It returns float value
Note : Strength value ranges from 0 to 1.0
Below is the implementation
# 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) # setting font label.setFont(QFont('Arial', 15)) # creating a color effect color_effect = QGraphicsColorizeEffect() # setting color to color effect color_effect.setColor(Qt.darkRed) # setting strength color_effect.setStrength(0.5) # 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 strength strength = color_effect.strength() # setting text to result label result.setText("Color : " + str(strength)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
