In this article we will see how we can change the slider representation of 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. There are basically four slider change options as follows: slider range change, slider orientation change, slider step change and slider value change.
In order to do this we will use sliderChange method with the scroll bar object.
Syntax : scroll.sliderChange(sliderchange)
Argument : It takes slider change object as argument
Return : It returns None
Below is the implementation
Python3
# importing librariesfrom PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGuifrom PyQt5.QtGui import *from PyQt5.QtCore import *import sysclass 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 change scroll.sliderChange(QAbstractSlider.SliderOrientationChange) # creating a label label = QLabel("neveropen", self) # setting geometry to the label label.setGeometry(200, 100, 300, 80) # making label multi line label.setWordWrap(True)# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
