PyQt5 QScrollBar – Checking Slider Down Property
In this article we will see how we can check the slider down property 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. This property holds whether the slider is pressed down. The property is set by subclasses in order to let the abstract slider know whether or not tracking has any effect. Changing the slider down property emits the slider pressed and slider released signals. It can be set with the help of setSliderDown method.
In order to do this we will use isSliderDown method with the scroll bar object.
Syntax : scroll.isSliderDown()
Argument : It takes no argument
Return : It returns bool
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 down scroll.setSliderDown(True) # 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) # checking if slider is down value = scroll.isSliderDown() # setting text to the label label.setText("Is Slider Down: " + str(value))# create pyqt5 appApp = QApplication(sys.argv)# create the instance of our Windowwindow = Window()# start the appsys.exit(App.exec()) |
Output :
