In this article, we will see how we can get the accepted signal of the QColorDialog widget. This signal is emitted when the dialog has been accepted either by the user or by calling accept() or done() with the QDialog::Accepted argument. Note : This signal is not emitted when hiding the dialog with hide() or setVisible(false). This includes deleting the dialog while it is visible. In order to do this we use accepted method with the QColorDialog object
Syntax : dialog.accepted.connect(lambda: print(“Accepted Signal”) Argument : It takes method as argument Action Performed : It will call the passed method when accepted signal emitted
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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) dialog.accepted.connect(lambda: print("accepted Signal")) # making color done # accepting the color dialog.done(1) # executing the dialog dialog.exec_() # creating label label = QLabel("neveropen", 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 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
Accepted Signal Accepted Signal
