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 ()) |
