In PyQt5, 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. Syntax:
listWidget = QListWidget()
There are two ways to add items to the list.
- They can be constructed with the list widget as their parent widget.
QListWidgetItem("Geeks", listWidget)
QListWidgetItem("For", listWidget)
QListWidgetItem("Geeks", listWidget)
- They can be constructed with no parent widget and added to the list later.
listWidgetItem = QListWidgetItem("GeeksForGeeks")
listWidget.addItem(listWidgetItem)
Some of the most frequently used methods in QListWidget:
addItem() : To add QListWidgetItem object in list addItems() : To add multiple QListWidgetItem objects insertItem() : It adds item at specified position clear() : To delete all the items present in the list count() : To count number of items present in the list
Below is the code –
Python3
import sysfrom PyQt5.QtWidgets import QApplication, QWidget, QListWidget, QVBoxLayout, QListWidgetItemclass Ui_MainWindow(QWidget): def __init__(self, parent = None): super(Ui_MainWindow, self).__init__(parent)if __name__ == '__main__': app = QApplication(sys.argv) window = QWidget() listWidget = QListWidget() window.setWindowTitle("Demo for QListWidget") QListWidgetItem("Geeks", listWidget) QListWidgetItem("For", listWidget) QListWidgetItem("Geeks", listWidget) listWidgetItem = QListWidgetItem("GeeksForGeeks") listWidget.addItem(listWidgetItem) window_layout = QVBoxLayout(window) window_layout.addWidget(listWidget) window.setLayout(window_layout) window.show() sys.exit(app.exec_()) |
