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
Python3
# 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("neveropen", 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 ()) |
Output :
