QCompleter and QListWidget as custom popup issue - qt

Question

I have a QCompleter using a QStringListModel for my QPlainTextEdit (check this example):
QStringListModel* model = new QStringListModel(names);
QCompleter* completer = new QCompleter(model);
completer->setCompletionMode(QCompleter::PopupCompletion);
completer->setModelSorting(QCompleter::UnsortedModel);
It works fine. Now I need some Icon, Tooltips for each suggestion I'm trying to use a QListWidget as custom popup:
QListWidget* w = new QListWidget();
foreach(name, names) {
QListWidgetItem* i = new QListWidgetItem(name);
i->setIcon(/*my Icon*/);
i->setToolTip("");
w->addItem(i);
}
completer->setPopup(w);
The popup ok, just like I need, but the completion no more work. I cannot type the text to make it filter the suggestion, just Up/Down key.
I have try:
completer->setModel(w->model());
but no help!
What is my misstake or just QStringListModel give me the ability to filter the suggestions? What do you suggest?
Thanks you!

I mostly deal with PyQt, but same deal. My syntax may be off, but you should use a QStandardItemModel vs. a QStringListModel. From there, you can leave it as the standard popup (QListView)
Something like:
QStandardItemModel* model = new QStandardItemModel();
// initialize the model
int rows = names.count(); // assuming this is a QStringList
model->setRowCount(rows);
model->setColumnCount(1);
// load the items
int row = 0;
foreach(name, names) {
QStandardItem* item = new QStandardItem(name);
item->setIcon(QIcon(":some/icon.png");
item->setToolTip("some tool tip");
model->setItem(row, 0, item);
row++;
}
completer->setModel(model);
completer->popup()->setModel(model); // may or may not be needed
