In this article we will see how we can get the child of QColorDialog widget with the help of type of child. QColorDialog widget consist of multiple widgets like QLabel, QPushButton, QSpinBox and many other widgets. Combining these widgets forms the color dialog.

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

Syntax : dialog.findChild(w_type)

Argument : It takes child type as argument

Return : It returns child object

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)
  
        dialog.setSizeGripEnabled(True)
  
        # 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 child of color dialog 
        value = dialog.findChild(QSpinBox)
  
        # setting text to the label
        label.setText("Child QSpinBox type : " + str(value))
  
  
# create pyqt5 app
App = QApplication(sys.argv)
  
# create the instance of our Window
window = Window()
  
# start the app
sys.exit(App.exec())
