PyQt5 QSpinBox β Checking if it is read only
In this article we will see how we can check if the spin box is read only or not, read only means that user will not be able to change the value of it. It is similar to making a spin box disabled but when spin box is disabled its other properties are turned off as well but in read only no one can edit the text. By default spin box is editable although we can make it read only using setReadOnly method. In order to do this we use isReadOnly method with the spin box object.
Syntax : spin_box.isReadOnly() Argument : It takes no argument Return : It returns bool
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 , 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") # making spin box read only self .spin.setReadOnly( True ) # 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 is read only value = self .spin.isReadOnly() # setting text to the label self .label.setText("Is read only ? " + str (value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
