In this article we will see how we can get the rejected signal of the QColorDialog widget. This signal is emitted when the dialog has been rejected either by the user or by calling reject() or done() with the QDialog::Rejected 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 rejected method with the QColorDialog object
Syntax : dialog.rejected.connect(lambda: print(“Rejected Signal”)
Argument : It takes method as argument
Action Performed : It will call the passed method when rejected signal emitted
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) # getting rejected signal dialog.rejected.connect(lambda: print("Rejected Signal")) # making color done # rejecting the color dialog.done(0) # 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 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
Rejected Signal Rejected Signal
