PyQt5 QColorDialog - Getting Layout

Last Updated : 24 Jun, 2020

In this article we will see how we can get the layout of the QColorDialog. Layout is the map of all the child existed in the dialog, layout consist of the children of the dialog, each widget is added one by one in the layout. In order to do this we use layout method with the QColorDialog object

Syntax : dialog.layout() Argument : It takes no argument Return : It returns QLayout object

Below is the implementation

Python3 1==

# 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 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(10, 10, 400, 280)

        # 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 dialog layout
        value = dialog.layout()

        # setting text to the label
        label.setText("Layout : " + str(value))



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

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

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