Question

How can I add a checkbox/radiobutton/combobox to a QTableWidget or a QListWidget?

Answer 1

For a checkbox using the item’s setCheckState method should do what you need both for list and table widgets. See if code below would work for you:

List widget:

QListWidgetItem *item0 = new QListWidgetItem(tr("First"), listWidget);
QListWidgetItem *item1 = new QListWidgetItem(tr("Second"), listWidget);

item0->setCheckState(Qt::Unchecked);
item1->setCheckState(Qt::Checked);

Table widget:

QTableWidgetItem *item2 = new QTableWidgetItem("Item2");
item2->setCheckState(Qt::Checked);
tableWidget->setItem(0, 0, item2);

You can use delegates (QItemDelegate) for other types of editor’s widgets, example is here: Spin Box Delegate Example.

I hope this helps.
