In this article we will see how we can get the editing finished signal of the QDoubleSpinBox. This signal is emitted when editing is finished. This happens when the double spinbox loses focus and when enter is pressed. This is very helpful signal as it is emitted when user confirms value in the spin box.
In order to do this we will use editingFinished method with the QDateTimeEdit object.
Syntax : dd_spin.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 double spin box d_spin = QDoubleSpinBox(self) # setting geometry to the double spin box d_spin.setGeometry(100, 100, 150, 40) # step type step_type = QAbstractSpinBox.AdaptiveDecimalStepType # adaptive step type d_spin.setStepType(step_type) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(100, 200, 300, 80) # making label multi line label.setWordWrap(True) # getting editing finished signal of double spin box d_spin.editingFinished.connect(lambda: spin_method()) def spin_method(): # setting text to the label 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 :
