How to make items in QListWidget multiline?

Question

There is QListWidget. If I add an item with the text like "Line1\nLine2" I get an item containing a one string.
How can I make this item containing two strings?

I added an item to the QListWidget in the following way: some_list_widget.addItem(QString("Line1\nLine2")); and I get what you want: imgur.com/a/TFv5a , You could give more detail. — eyllanesc

@eyllanesc Wow. Same result. Why if add the item using QtDesigner I don't get the same result? — Ufx

You could add two lines to QListWidget in two way:

First:

 listWidget->addItem(tr("Line1\nLine2"));

or

new QListWidgetItem(tr("Line4\nLine5"), listWidget);

and that should work as per common testing.

Second, and the better way is to add multiple items using addItems() with QStringList

QStringList items; items << "Line1"; items << "Line2"; listWidget->addItems(items);

It seems that the editor adds one more backslash as the following image shows:

The solution is simple, you must edit the text in Object Inspector and add it there directly as I show below:
