In this article we will see how we can execute the QColorDialog widget, executing means to opening it. There are basically two ways of opening the QColorDialog one is to call the getColor
method, this is a static way that will open the new instance of QColorDialog every time, this way is useful for quick uses but not preferred. The second way is by executing it, how the QColorDialog
looks like.
In order to do this we use exec_()
method with the QColorDialog object
Syntax : dialog.exec_()
Argument : It takes no argument
Action Performed : It opens the QColorDialog widget
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 )
# executing the dialog
dialog.exec_()
# creating label to display the color
label = QLabel( "GfG" , self )
# setting geometry to the label
label.setGeometry( 100 , 100 , 200 , 60 )
# making label multi line
label.setWordWrap( True )
# setting stylesheet of the label
label.setStyleSheet( "QLabel"
"{"
"border : 5px solid black;"
"}" )
color = Qt.green
# 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 ())
