Disable Item in Qt Combobox

Question

I can\'t find a standard way to disable an individual item in a Qt combo box. Is there a facility to do this in Qt that I am missing?

Answer 1

You can use the model of a QListWidget as a proxy.

QComboBox *combo = new QComboBox(this);
QListWidget *contents = new QListWidget(combo);
contents->hide();
combo->setModel(contents->model());

/* Populate contents */
contents->addItem("...");    // Etcetera

Then, this method will disable an item:

void disableItem(int index)
{
    QListWidgetItem *item = contents->item(index);
    item->setFlags(item->flags() & ~Qt::ItemIsEnabled);
}
