PyQt5 QColorDialog – Making color done
In this article we will see how we can done the color in the QColorDialog widget. This closes the dialog and sets its result code to r. The finished signal will be emitted, if r is QDialog::Accepted
or QDialog::Rejected
, the accepted or the rejected signals will also be emitted, respectively.
In order to do this we use done
method with the QColorDialog object
Syntax : dialog.done(1)
Argument : It takes integer as argument if 0 is passed it will reject the color if 1 is passed it will accept the color
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) # making color done dialog.done( 1 ) # 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 :
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 by calling the done method
