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
