In this article we will see how we can check if the spin box has given attribute or not, attributes are basically the qualities of the spin box, some attributes are similar to the spin box flags. There are many attributes available for the spin box like WA_AcceptDrops, WA_AlwaysShowToolTips etc.
In order to do this we use testAttribute
method with the spin box object.
Syntax : spin_box.testAttribute((Qt.WA_Disabled)
Argument : It takes QWidget Attribute object as 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 , 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( 1 , 999999 )
# setting prefix to spin
self .spin.setPrefix( "PREFIX " )
# setting suffix to spin
self .spin.setSuffix( " SUFFIX" )
# setting attribute to the spin box
self .spin.setAttribute(Qt.WA_Disabled)
# creating a label
self .label = QLabel( self )
# making label multi line
self .label.setWordWrap( True )
# setting label geometry
self .label.setGeometry( 100 , 200 , 250 , 60 )
# checking if spin box has the disabled attribute
value = self .spin.testAttribute(Qt.WA_Disabled)
# setting text to the label
self .label.setText( "It has disabled attribute: " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
