In this article we will see how we can set position of slider in QScrollBar programmatically. QScrollBar is a control that enables the user to access parts of a document that is larger than the widget used to display it. Slider is the scroll-able object inside the bar. We can change its position with the help of mouse and keyboard.
In order to do this we will use setSliderPosition method with the scroll bar object.
Syntax : scroll.setSliderPosition(n)
Argument : It takes integer as argument
Return : It returns None
Example: 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 , 500 , 400 )
# calling method
self .UiComponents()
# showing all the widgets
self .show()
# method for components
def UiComponents( self ):
scroll = QScrollBar( self )
# setting geometry of the scroll bar
scroll.setGeometry( 100 , 50 , 30 , 200 )
# making its background color to green
scroll.setStyleSheet( "background : lightgrey;" )
# setting slider position
scroll.setSliderPosition( 50 )
# creating a label
label = QLabel( "GeeksforGeeks" , self )
# setting geometry to the label
label.setGeometry( 200 , 100 , 300 , 80 )
# making label multi line
label.setWordWrap( True )
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
