PyQt5 QColorDialog – Getting Color Dialog Options
In this article we will see how we can get the options of the QColorDialog widget. There are basically three dialog options available for the QColorDialog widget, below are 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
We use setOption method to set the options to the QColorDialog widget.
In order to do this we use options method with the QColorDialog object
Syntax : dialog.options()
Argument : It takes no argument
Return : It returns QColorDialog’s option object
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 option dialog.setOption(QColorDialog.ShowAlphaChannel) # executing the dialog dialog.exec_() # creating label to display the color label = QLabel("GfG", 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;" "}") color = Qt.darkBlue # 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) # getting the option of color dialog option = dialog.options() # setting text to the label label.setText("Options : " + str(option)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
