PyQt5 QColorDialog – Finished Signal

  • Last Updated : 01 Aug, 2020

In this article we will see how we can get the finished signal of the QColorDialog widget. This signal is emitted when the dialog’s result code has been set, either by the user or by calling done(), accept(), or reject().

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 finished method with the QColorDialog object

Syntax : dialog.finished.connect(lambda: print(“Finished Signal”)

Argument : It takes method as argument

Action Performed : It will call the passed method when finished 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)
        # getting finished signal
        # printing message when signal recieved
        dialog.finished.connect(lambda: print("Finieshed Signal Emitted"))
        # 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;"
        color =
        # setting graphic effect to the label
        graphic = QGraphicsColorizeEffect(self)
        # setting color to the graphic
        # setting graphic to the label
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app

Output :

Finieshed Signal Emitted
