PyQt5 listview QListWidget

Hello, we continue with listview. What is a listview? It is used to show a certain group of items in a different type list, with order or without order, it’s up to us.

For example, consider a list of students with names. We may not see them and take action on them. We may want to see the records in a table in the database. I can say that it is ideal for such listing processes.

Example :

listView object

self.list_view = QListWidget(self)

to add when we enter data from the textbox on the form

self.list_view.addItem(QListWidgetItem(self.textbox.toPlainText()))

To delete an entry in listview

selected_row = self.list_view.currentRow()
item = self.list_view.takeItem(selected_row)
del item

Result
