In this article we will see how we can check if the color 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 color effect is widget type or not we use isWidgetType method.
Syntax : color_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__() # 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 widget type check = self.color_effect.isWidgetType() # setting text to result label result.setText("Widget ? : " + 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 :
