PyQt5 QScrollBar – Setting Cursor

0 0 1 minute read

In this article we will see how we can set cursor to the QScrollBar. 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. Setting cursor means to set special cursor to the scroll bar which is only for the scroll bar only.

In order to do this we will use setCursor method with the scroll bar object. Syntax : scroll.setCursor(cursor) Argument : It takes QCursor object as argument Return : It returns None

Below is the implementation

Python3

# 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 cursor to the scroll bar
        scroll.setCursor(Qt.OpenHandCursor)
 
        # creating a label
        label = QLabel("zambiatek", self)
 
        # setting geometry to the label
        label.setGeometry(200, 100, 300, 80)
 
        # making label multi line
        label.setWordWrap(True)
 
        # getting value changed signal
        scroll.valueChanged.connect(lambda: do_action())
 
        # method called when signal is emitted
        def do_action():
             
            # setting text to the label
            label.setText("Current Value : " + str(scroll.value()))
 
 
# create pyqt5 app
App = QApplication(sys.argv)
 
# create the instance of our Window
window = Window()
 
# start the app
sys.exit(App.exec())
