PyQt5 QSpinBox – Checking if the arrow buttons are removed or not
In this article we will see how we can check if the spin box arrow buttons are removed or not, basically there are two buttons in the spin box one for incrementing the value and second for decrementing the value. In order to remove the buttons we use setButtonSymbols method. In order to check we will use buttonSymbols method.
Syntax : spin_box.buttonSymbols()
Argument : It takes no argument
Return : It returns QAbstractSpinBox object but its corresponding value is 2 if buttons are removed
Below is the implementation
Python3
# 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 , 150 , 40 ) # removing the buttons self .spin.setButtonSymbols(QAbstractSpinBox.NoButtons) # creating label label = QLabel( self ) # setting geometry to the label label.setGeometry( 100 , 160 , 200 , 30 ) # getting the button symbol symbol = self .spin.buttonSymbols() # checking if arrow button is removed if symbol = = 2 : text = "No Arrow buttons" else : text = " Arrow buttons" # setting text to the label label.setText(text) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
