createEvent not called in delegate
Message 1 in thread
Hi,
I am lost in an apparently trivial problem with a delegate [QT Version
is 4.3.2].
I have a QListView Object and a delegate widget that display two labels
one near the other. It should be very simple, I have followed the
SpinBoxDelegate sample:
lass DoubleItemDelegate : public QItemDelegate
{
Q_OBJECT;
public:
DoubleItemDelegate(QObject *parent = 0);
virtual ~DoubleItemDelegate();
QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option,
const QModelIndex &index) const;
void setEditorData(QWidget *editor, const QModelIndex &index) const;
void setModelData(QWidget *editor, QAbstractItemModel *model,
const QModelIndex &index) const;
void updateEditorGeometry(QWidget *editor,
const QStyleOptionViewItem &option, const QModelIndex &index) const;
protected:
};
(cut&pasted from the SpinBoxDelegate sample).
Then, I instantiate my QListView, I setup my model (a
QStandardItemModel), instantiate a delegate be using a proper factory
(...) and finally call list->setItemDelegate (delegate):
if (itemFactory) {
qDebug ("Installing new delegate");
QItemDelegate *delegate = itemFactory->create(list);
list->setItemDelegate(delegate);
}
After that I add some data to the model.
I can see my list, but it do not use the delegate, infact while using
qDebug() I can see that the constructor is reached but the createEditor
method is never called.
What am I missing?!?
Thank you very much
