The problem is, that I want to resize the child item to the size of the delegate item and not the delegate to the child. I tried this by calling the following method after I changed the model:
void QuickItemMngrServiceImpl::anchorItems()
{
QQmlContext *ctxt = m_viewer->rootContext();
Q_FOREACH(QObject *item, m_items)
{
QQmlExpression expr(ctxt, item, "parent");
QQmlProperty prop(item, "anchors.fill");
prop.write(expr.evaluate());
}
}
But this works only for the items, that are visible at the beginning.
