In this article we will see how we can set margin to the spin box, by default there is no margin set to the spin box i.e their margin values are zero. Although we can change that, setting margin to the spin box will not display any change in the spin box due to overriding take place by the widget to maintain its structure. But in order to set margin to the spin box we have set margin to the spin box’s line edit object by which we can display the margin in spinbox.
In order to do this we use setContentsMargins method.
Syntax : line_edit.setContentsMargins(left, top, right, bottom)
Here line_edit is the QLineEdit object of the spin boxArgument : It takes four integer as argument
Return : It returns None
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( 0 , 999999 )
# setting prefix to spin
self .spin.setPrefix( "Prefix " )
# setting suffix to spin
self .spin.setSuffix( " Suffix" )
# getting line edit object
line_edit = self .spin.lineEdit()
# setting margin to the line edit
line_edit.setContentsMargins( 50 , 20 , 5 , 5 )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
window.spin.setFocus() # start the app sys.exit(App. exec ())
