In this article we will see how we can access the line edit object of the spin box, line edit is widget in PyQt5 which is used to display text and accept the input text. By default spin box has its own line edit object although we can add our own line edit object to it with the help of setLineEdit
method.
In order to do this we use lineEdit method
Syntax : spin_box.lineEdit()
Argument : It takes no argument
Return: It returns line edit object
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 prefix to spin self .spin.setPrefix( "Prefix " ) # setting suffix to spin self .spin.setSuffix( " Suffix" ) # get the line edit object of spin box line = self .spin.lineEdit() # creating a label label = QLabel( self ) # setting text to the label label.setText( str (line)) # adjust the size of the label label.adjustSize() # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
