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 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 ):
# 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("GeeksforGeeks", 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 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
