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 librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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("neveropen", 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
