PyQt5 QColorDialog – Custom Color Count

In this article we will see how we can get the number of custom colors supported by QColorDialog widget. Custom colors are the color made by the user they can be set at the run time with the help of mouse although we can add custom color programmatically with the help of setCustomColor method, by default all custom colors are white. We can get the custom color with the help of customColor method. 

Below is how the custom color in color dialog looks like

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

Syntax : dialog.setCount() 

Argument : It takes no argument 

Return : It returns integer

Below is the implementation 

Python3

# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui

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 custom colors
        dialog.setCustomColor(1, Qt.red)
        dialog.setCustomColor(2, Qt.green)
        dialog.setCustomColor(3, Qt.yellow)
        dialog.setCustomColor(4, Qt.blue)


        # 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 custom color
        color = dialog.customColor(4)

        # 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)

        # getting custom color count
        value = dialog.customCount()

        # setting text to the label
        label.setText("Custom Color Count : " + str(value))



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())

Output :
