In this article we will see how we can get signal when return key is pressed on QDateTimeEdit widget. QDateTime is basically a combination of QDate and QTime i.e it has both date and time. And QDateTimeEdit widget is used to show or receive the QDateTime. We can set QDateTime to it with the help of setDateTime method. In order to get the signal when return key is pressed we use editing finished signal, this signal is emitted when editing is finished. This happens when the QDateTime loses focus and when enter is pressed.
In order to do this we will use editingFinished method with the QDateTimeEdit object.
Syntax : datetimeedit.editingFinished.connect(method)
Argument : It takes method 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 QDateTimeEdit widget datetimeedit = QDateTimeEdit(self) # setting geometry datetimeedit.setGeometry(100, 100, 150, 35) # setting date time to it datetimeedit.setDateTime(QDateTime(2020, 10, 10, 11, 30)) # time time = QTime(21, 45) # setting only time datetimeedit.setTime(time) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(100, 160, 200, 60) # making label multi line label.setWordWrap(True) # getting editing finished signal datetimeedit.editingFinished.connect(lambda: label.setText("Editing Finished signal Emitted")) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
