PyQt5 – QColorDialog

QColorDialog It is a dialog box of a color picker widget. A color picker is a graphical user interface widget, usually found within graphics software or online, used to select colors and sometimes to create color schemes. Below is how the QColorDialog looks like

It is popup type widget in PyQt5 it basic use is to allow user to choose the color this widget is very useful in designing application like paint.

Example :
In this we will create a PyQt5 application which when executed will open the color dialog and when user choose the color and close the dialog there will be our main window which has a label and its color will be same as of the color selected in the dialog.4

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):

        # opening color dialog
        color = QColorDialog.getColor()

        # creating label to display the color
        label = QLabel(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;"
                            "}")

        # setting text to the label
        label.setText(str(color))

        # 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 :
