In this article we will see how we can set the custom color in the 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, by default all custom colors are white. Below is how the custom color in color dialog looks like
Syntax : dialog.setCustomColor(i, color) Argument : It takes integer i.e index and QColor object as argument Return : It returns None
Note : This function does not apply to the Native Color Dialog on the macOS platform. If you still require this function, use the QColorDialog.DontUseNativeDialog option. 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 )
# 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( 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 selected color
color = dialog.selectedColor()
# 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 ())
