PyQt5 QListWidget – Getting Auto Scroll Margin

06 Aug, 2020
In this article we will see how we can get auto scroll margin of the QListWidget. QListWidget is a convenience class that provides a list view with a classic item-based interface for adding and removing items. QListWidget uses an internal model to manage each QListWidgetItem in the list. This property holds the size of the area when auto scrolling is triggered. This property controls the size of the area at the edge of the viewport that triggers autoscrolling. The default value is 16 pixels although it can be changed with the help of setAutoScrollMargin method.
In order to do this we will use autoScrollMargin method with the list widget object.
Syntax : list_widget.autoScrollMargin()
Argument : It takes no argument
Return : It returns integer
Below is the implementation
# importing librariesfrom PyQt5.QtWidgets import * from PyQt5 import QtCore, QtGuifrom 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):          # creating a QListWidget        list_widget = QListWidget(self)          # setting geometry to it        list_widget.setGeometry(50, 70, 150, 80)          # list widget items        item1 = QListWidgetItem("PyQt5 Geeks for Geeks")        item2 = QListWidgetItem("B")        item3 = QListWidgetItem("C")        item4 = QListWidgetItem("D")          # adding items to the list widget        list_widget.addItem(item1)        list_widget.addItem(item2)        list_widget.addItem(item3)        list_widget.addItem(item4)          # setting drag and drop property        list_widget.setDragDropMode(3)          # setting auto scroll property        list_widget.setAutoScroll(True)          # setting auto scroll margin        list_widget.setAutoScrollMargin(20)            # setting word wrap property        list_widget.setWordWrap(True)          # creating a label        label = QLabel("GeesforGeeks", self)          # setting geometry to the label        label.setGeometry(230, 80, 280, 80)          # making label multi line        label.setWordWrap(True)          # getting auto scroll margin        value = list_widget.autoScrollMargin()          # setting text to the label        label.setText("Auto Scroll Margin : " + str(value))      # create pyqt5 appApp = QApplication(sys.argv)  # create the instance of our Windowwindow = Window()  # start the appsys.exit(App.exec())
