PyQt5 QColorDialog – Rejecting the color

In this article we will see how we can reject the color in the QColorDialog widget. Hides the modal dialog and sets the result code to Rejected., it is same when user press ‘Cancel’ button.

This method call the finished signal

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

Syntax : dialog.reject()

Argument : It takes no argument

Return : It returns None

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)

        # setting current color to the dialog
        dialog.setCurrentColor(Qt.red)

        # accepting the color
        # now color will become selected one
        dialog.accept()

        # rejecting the color
        dialog.reject()

        # executing the dialog
        # dialog.exec_()


        # creating label
        label = QLabel("GeeksforGeeks", self)

        # setting geometry to the label
        label.setGeometry(100, 100, 300, 80)

        # making label multi line
        label.setWordWrap(True)

        # setting stylesheet of the label
        label.setStyleSheet("QLabel"
                            "{"
                            "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
        graphic.setColor(color)

        # setting graphic to the label
        label.setGraphicsEffect(graphic)

        # 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
sys.exit(App.exec())

Output :

Note : In this implementation we didn’t execute the color dialog because we set the current color and accept the color programmatically will make it selected color instead of white which is default but then the reject method get called which will remove the color so the color becomes black
