In this article we will see how we can set the current color of the QColorDialog widget. User can select the color with the mouse or using the spin boxes present there but the initial color always remain white in order to change this we can set the current of the color dialog before executing it.
In order to do this we use setCurrentColor
method with the QColorDialog object
Syntax : dialog.setCurrentColor(Qt.red)
Argument : It takes QColor object as argument
Return : It returns None
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 current color dialog.setCurrentColor(Qt.red) # 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;" "}" ) color = Qt.darkBlue # 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 ()) |
