In this article we will see how we can if the QDoubleSpinBox is non editable or editable. By default when we create a double spin box it is editable i.e its value can be changed by user any time, although by making it non editable with the help of setReadOnly method, then its value can’t be changed, user can only view the value.
In order to do this we will use
isReadOnlymethod with the double spin box object.Syntax : dd_spin.isReadOnly()
Argument : It takes no argument
Return : It returns bool
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) # setting decimal precision d_spin.setDecimals(1) # step type step_type = QAbstractSpinBox.AdaptiveDecimalStepType # adaptive step type d_spin.setStepType(step_type) # making it non editable d_spin.setReadOnly(True) # 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) # checking if it is non editable value = d_spin.isReadOnly() # setting text to the label label.setText("Non Editable ? : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
