In this article we will see how we can reject the color in the QColorDialog widget. Hides the modal dialog and sets the result code to Rejected., it is same when user press ‘Cancel’ button.
This method call the finished signal
In order to do this we use reject
method with the QColorDialog object
Syntax : dialog.reject()
Argument : It takes no 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 to the dialog
dialog.setCurrentColor(Qt.red)
# accepting the color
# now color will become selected one
dialog.accept()
# rejecting the color
dialog.reject()
# 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)
# setting text to the label
label.setText( "Accepted Color : " + str (color))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
|
Output :
Note : In this implementation we didn’t execute the color dialog because we set the current color and accept the color programmatically will make it selected color instead of white which is default but then the reject method get called which will remove the color so the color becomes black
