PyQt5 QColorDialog – Accepted Signal

  • Last Updated : 01 Aug, 2020

In this article, we will see how we can get the accepted signal of the QColorDialog widget. This signal is emitted when the dialog has been accepted either by the user or by calling accept() or done() with the QDialog::Accepted argument.

Note : This signal is not emitted when hiding the dialog with hide() or setVisible(false). This includes deleting the dialog while it is visible.

In order to do this we use accepted method with the QColorDialog object

Syntax : dialog.accepted.connect(lambda: print(“Accepted Signal”)

Argument : It takes method as argument

Action Performed : It will call the passed method when accepted signal emitted

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):
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 500, 400)
        # calling method
        # showing all the widgets
    # method for components
    def UiComponents(self):
        # creating a QColorDialog object
        dialog = QColorDialog(self)
        # setting current color to the dialog
        dialog.accepted.connect(lambda: print("Accpeted Signal"))
        # making color done
        # accepting the color
        # executing the dialog
        # creating label
        label = QLabel("GeeksforGeeks", self)
        # setting geometry to the label
        label.setGeometry(100, 100, 300, 80)
        # making label multi line
        # setting stylesheet of the label
                            "border : 5px solid black;"
        # getting the selected color
        color = dialog.selectedColor()
        # setting graphic effect to the label
        graphic = QGraphicsColorizeEffect(self)
        # setting color to the graphic
        # setting graphic to the label
        # setting text to the label
        label.setText("Accepted Color : " + str(color))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app

Output :
