In this article we will see how we can check if the opacity effect of the label is widget type or not. Widget type allows user to know if color effect object is widget type just like label, buttons etc or not.
In order to check the opacity effect is widget type or not we use isWidgetType method.
Syntax : opacity_effect.isWidgetType()
Argument : It takes no argument
Return : It returns bool
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__() # 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)) # setting style sheet of the label label.setStyleSheet("QLabel" "{" "border : 2px solid green;" "background : lightgreen;" "}") # creating a opacity effect self.opacity_effect = QGraphicsOpacityEffect() # setting opacity level self.opacity_effect.setOpacity(0.3) # adding opacity effect to the label label.setGraphicsEffect(self.opacity_effect) # result label result = QLabel(self) # setting geometry of the result label result.setGeometry(200, 200, 300, 30) # checking opacity effect is widget type or not check = self.opacity_effect.isWidgetType() # setting text to the result label result.setText("Widget type? : " + str(check)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
