[Davidcheng]

why does this code not work for qt5.9 ? no item be selectted. i want to make 24 items to 2 columns, each item is clickable

the code comes from forum

ui->setupUi(this);

    QStandardItemModel model(5, 3);
    for(int i = 0; i < model.rowCount(); i++)
    {
        QStandardItem *col0 = new QStandardItem(QString("foobar%1").arg(i));
        QStandardItem *col1 = new QStandardItem(QString("foo%1").arg(i));
        QStandardItem *col2 = new QStandardItem(QString("bar%1").arg(i));

        model.setItem(i, 0, col0);
        model.setItem(i, 1, col1);
        model.setItem(i, 2, col2);
    }

    ui->comboBox->setModel(&model);
    QTreeView *treeView = new QTreeView(ui->comboBox);
    ui->comboBox->setView(treeView);

    treeView->setColumnHidden(0, true);
    treeView->setSelectionBehavior(QAbstractItemView::SelectRows);
    treeView->setAllColumnsShowFocus(true);
    treeView->setRootIsDecorated(false);
    treeView->header()->hide();

Hi
The "treeView->setSelectionBehavior(QAbstractItemView::SelectRows);"
tell it to select whole rows, not cells.
Try with
QAbstractItemView::SelectItems

@mrjj not work, not the reason

@Davidcheng

well code worked for me so you must provide more details to "not work"
in order to help you.

Shooting in the dark here but what about: http://doc.qt.io/qt-5/qcombobox.html#modelColumn-prop

The default is 0 and you hide that column

@VRonin comment //treeView->setColumnHidden(0, true); does not work.
