Completer on QItemDelegate

[jpn]

Actually, now that I give it a try I'm not even able to reproduce the problem. This works just fine for me (with both Qt 4.3.3 and a couple of weeks old snapshot of Qt 4.4):

// main.cpp
#include <QtGui>
 
class ItemDelegate : public QItemDelegate
{
public:
    ItemDelegate(QObject* parent = 0) : QItemDelegate(parent) { }
 
    QWidget* createEditor(QWidget* parent, const QStyleOptionViewItem& option, const QModelIndex& index) const
    {
        QWidget* editor = QItemDelegate::createEditor(parent, option, index);
        QLineEdit* lineEdit = dynamic_cast<QLineEdit*>(editor);
        if (lineEdit)
        {
            QStringList stringList = QStringList() << "foo" << "bar" << "baz";
            QCompleter* completer = new QCompleter(stringList, lineEdit);
            lineEdit->setCompleter(completer);
        }
        return editor;
    }
};
 
int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QTableWidget table(4, 4);
    table.setEditTriggers(QAbstractItemView::AllEditTriggers);
    table.setItemDelegate(new ItemDelegate(&table));
    table.show();
    return app.exec();
}

// main.cpp
#include <QtGui>

class ItemDelegate : public QItemDelegate
{
public:
    ItemDelegate(QObject* parent = 0) : QItemDelegate(parent) { }

    QWidget* createEditor(QWidget* parent, const QStyleOptionViewItem& option, const QModelIndex& index) const
    {
        QWidget* editor = QItemDelegate::createEditor(parent, option, index);
        QLineEdit* lineEdit = dynamic_cast<QLineEdit*>(editor);
        if (lineEdit)
        {
            QStringList stringList = QStringList() << "foo" << "bar" << "baz";
            QCompleter* completer = new QCompleter(stringList, lineEdit);
            lineEdit->setCompleter(completer);
        }
        return editor;
    }
};

int main(int argc, char* argv[])
{
    QApplication app(argc, argv);
    QTableWidget table(4, 4);
    table.setEditTriggers(QAbstractItemView::AllEditTriggers);
    table.setItemDelegate(new ItemDelegate(&table));
    table.show();
    return app.exec();
}

Doesn't it work for you?

When I compile your code as standalone application it works as expected, otherwise when I apply it on my code and on my view, it doesn't work :/ happens exactly the same thing. It is because I don't put AllEditTriggers, but I have only couple of them...try setting the AnyKeyPressed trigger .. doesn't work.

Could this be bug in Qt ?
