QListWidget

In this tutorial, we will learn QListWidget.

There is a big difference between QListWidget and QListView:

The QListView uses MVC, and will be covered in later section.

In this tutorial, we'll populate the items of the widget list and then when a button is clicked, it will make some changes on the currently selected item (text color and item background color).

Here is the code: dialog.cpp:

#include "dialog.h"#include "ui_dialog.h"Dialog::Dialog(QWidget *parent) : QDialog(parent), ui(new Ui::Dialog){ ui->setupUi(this); // populate the items of the list for(int i = 0; i < 10; i++) { ui->listWidget->addItem("Item " + QString::number(i)); }}Dialog::~Dialog(){ delete ui;}void Dialog::on_pushButton_clicked(){ // Get the pointer to the currently selected item. QListWidgetItem *item = ui->listWidget->currentItem(); // Set the text color and its background color using the pointer to the item. item->setTextColor(Qt::white); item->setBackgroundColor(Qt::blue);}

Note that we set the color of the text and background color after we get the ListWidgetItem:by calling QListWidgetItem * QListWidget::currentItem() const.
