In this article we will see how we can execute the QColorDialog widget, executing means to opening it. There are basically two ways of opening the QColorDialog one is to call the getColor method, this is a static way that will open the new instance of QColorDialog every time, this way is useful for quick uses but not preferred. The second way is by executing it, how the QColorDialog looks like.
In order to do this we use exec_() method with the QColorDialog object
Syntax : dialog.exec_()
Argument : It takes no argument
Action Performed : It opens the QColorDialog widget
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, 500, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for components def UiComponents(self): # creating a QColorDialog object dialog = QColorDialog(self) # executing the dialog dialog.exec_() # creating label to display the color label = QLabel("GfG", self) # setting geometry to the label label.setGeometry(100, 100, 200, 60) # making label multi line label.setWordWrap(True) # setting stylesheet of the label label.setStyleSheet("QLabel" "{" "border : 5px solid black;" "}") color = Qt.green # setting graphic effect to the label graphic = QGraphicsColorizeEffect(self) # setting color to the graphic graphic.setColor(color) # setting graphic to the label label.setGraphicsEffect(graphic) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
