In this article we will see how we can get position of slider in 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. We can change its position with the help of mouse and keyboard. Also we can change its position programmatically with the help of setSliderPosition method.
In order to do this we will use sliderPosition method with the scroll bar object.
Syntax : scroll.sliderPosition()
Argument : It takes no argument
Return : It returns integer
Example: 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 position scroll.setSliderPosition(50) # 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) # getting current position of the slider value = scroll.sliderPosition() # setting text to the label label.setText("Slider Position : " + str(value))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
