In this article we will see how we can set multiple options of the QColorDialog widget. There are basically three dialog options available for the QColorDialog widget, below is the options
1. ShowAlphaChannel : Allow the user to select the alpha component of a color
2. NoButtons : Don’t display OK and Cancel buttons
3. DontUseNativeDialog : Use Qt’s standard color dialog instead of the operating system native color dialog
By default all options are disabled, we can set single option with the help of setOption
method
Note : Options should be set before showing the dialog. Setting them while the dialog is visible is not guaranteed to have an immediate effect on the dialog (depending on the option and on the platform).
In order to do this we use setOptions
method with the QColorDialog object
Syntax : dialog.setOptions(QColorDialog.ShowAlphaChannel and QColorDialog.DontUseNativeDialog)
Argument : It takes option objects 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 multiple options
dialog.setOptions(QColorDialog.DontUseNativeDialog and QColorDialog.ShowAlphaChannel)
# 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;"
"}" )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
