Worse, the explicit assignment from QML breaks any binding set on <tt style="background: #ebebeb; font-size: 13px;">currentIndex</tt>.<br />
In the handler that's called when the delegate model creates a delegate it does the following</p>
<div class="remarkup-code-block" style="margin: 12px 0;" data-code-lang="text" data-sigil="remarkup-code-block"><pre class="remarkup-code" style="font: 11px/15px "Menlo", "Consolas", "Monaco", monospace; padding: 12px; margin: 0; background: rgba(71, 87, 120, 0.08);">void QQuickComboBoxPrivate::createdItem(int index, QObject *object)
{
...
QQuickAbstractButton *button = qobject_cast<QQuickAbstractButton *>(object);
if (button) {
button->setFocusPolicy(Qt::NoFocus);
connect(button, &QQuickAbstractButton::clicked, this, &QQuickComboBoxPrivate::itemClicked);
connect(button, &QQuickAbstractButton::hoveredChanged, this, &QQuickComboBoxPrivate::itemHovered);
