In this article we will see how we can get the property value of the spin box, properties are the information added by the developer to tell about the properties of the spin box, for example, if spin box has ability to loop the values, the developer will add this property so that other developer can see this and get to know about the property. Properties are added using setProperty
method.
In order to do this we use property method
Syntax : spin_box.property(property)
Argument : It takes string as argument
Return : It returns integer
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 , 600 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for widgets
def UiComponents( self ):
# creating spin box
self .spin = QSpinBox( self )
# setting geometry to spin box
self .spin.setGeometry( 100 , 100 , 250 , 40 )
# setting range to the spin box
self .spin.setRange( 0 , 999999 )
# setting prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# adding property to the spin box
self .spin.setProperty( "Dynamic" , 1 )
# adding property to the spin box
self .spin.setProperty( "Has suffix" , 1 )
# creating label
self .label = QLabel( self )
# setting geometry to the label
self .label.setGeometry( 100 , 200 , 200 , 70 )
# making it multi line label
self .label.setWordWrap( True )
# property
property_name = "Dynamic"
# getting property value
value = self .spin. property (property_name)
# setting text to the label
self .label.setText( "Property Name : " + property_name +
" Property Value : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
window.spin.setFocus() # start the app sys.exit(App. exec ())
