In this article we will see how we can check if the color effect of the label is disabled or not. In order to make the color effect disable we use setEnabled method. In order to check the color effect is disable and enable we use isEnabled method.
Syntax : color_effect.isEnabled() Argument : It takes no argument Return : It returns bool
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 self.color_effect = QGraphicsColorizeEffect() # setting color to color effect self.color_effect.setColor(Qt.darkBlue) # adding color effect to the label label.setGraphicsEffect(self.color_effect) # creating result label result = QLabel(self) # setting geometry to the result result.setGeometry(200, 200, 300, 30) # checking if color effect is enabled check = self.color_effect.isEnabled() # setting text to result label result.setText("Enabled ? : " + str(check))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
