In this article we will see how we can get the size increment value of spin box or not. Size increment is used when spin box size is changeable with the main window size. Base size is used to calculate a proper spin box size if the spin box defines sizeIncrement. By default, for a newly-created spin box, this property contains a size with zero width and height. WE can set the size increment value with the help of setSizeIncrement
method.
Below is the formula for getting new spin box size when main window get bigger.
width = baseSize().width() + i * sizeIncrement().width() height = baseSize().height() + j * sizeIncrement().height() Here i, j are the size increment in the main window
In order to do this we use sizeIncrement
method with the spin box object.
Syntax : spin_box.sizeIncrement()
Argument : It takes no argument
Return : It returns QSize 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 range to the spin box
self .spin.setRange( 0 , 9 )
# setting prefix to spin
self .spin.setPrefix( "PREFIX " )
# setting suffix to spin
self .spin.setSuffix( " SUFFIX" )
# setting size increment
self .spin.setSizeIncrement( 10 , 10 )
# 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 )
# getting the size increment value
value = self .spin.sizeIncrement()
# setting text to the label
self .label.setText( "Size increment : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
