In this article we will see how we can set range to the spin box, by default when we create a spin box it range varies from 0 to 99 i.e minimum value(lower bound) is 0 and maximum value(maximum bound) is 99 although we can change this range.
In order to do this we will use setRange
method.
Syntax : spin_box.setRange(min_value, max_value)
Argument : It takes two integer i.e minimum and maximum value as argument
Return : 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 , 150 , 40 ) # setting range self .spin.setRange( - 1 , 1 ) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
