In this article we will see how we can add extra widget to the QColorDialog. Extra widget is like extra functionality added to the color dialog, it can be label push button or any thing else, below is how the extra widget will look like
Implementation Steps:
1. Crate a main window class
2. Inside the main window class create a QColorDialog object
3. Add properties to the color dialog
4. Create a label and set its properties
5. Add this label to the layout of the dialog object
6. Execute the dialog
7. Delete the main window class
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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("Geeks for Geeks", self) label.setAlignment(Qt.AlignCenter) # 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) layout = dialog.layout() layout.addWidget(label) dialog.setLayout(layout) # getting dialog layout # value = dialog.layout() dialog.exec_() # setting text to the label # label.setText("Layout : " + str(value)) self.deleteLater() # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
