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
isReadOnly
method 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( "GeeksforGeeks" , 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 ())
