The delegate function: createEditor(...) doesn't get called when using a QTreeWidget.
Double clicking on an item in the tree widget has no effect.
Does somebody see what I'm doing wrong?

Qt Code: 
  1. int main(int argc, char *argv[])
  2. {
  3. 	QApplication app(argc,argv);
  4.         QTreeWidget* tree = new QTreeWidget;
  5.  
  6. 	tree->setItemDelegate(new MyDelegate);
  7. 	tree->setEditTriggers(QAbstractItemView::DoubleClicked | QAbstractItemView::SelectedClicked);
  8.  
  9. 	tree->setColumnCount(1);
  10.  
  11. 	QTreeWidgetItem *item01 = new QTreeWidgetItem(tree);
  12. 	item01->setData(0, Qt::EditRole /*Qt::DisplayRole*/, QVariant("item01"));
  13. 	item01->setText(0, "item01");
  14. 	tree->addTopLevelItem(item01);
  15.  
  16. 	tree->show();
  17. 	return app.exec();
  18. }

The implementation of the delegate class doesn't matter. The create editor method doesn't get called. If I use a QTableWidget instead of a QTreeWidget, it works fine. The class declaration of the delegate looks like this:
Qt Code: 
  1. #include <QStyledItemDelegate>
  2.  
  3. class MyDelegate : public QStyledItemDelegate
  4. {
  5. 	Q_OBJECT
  6. public:
  7. 	MyDelegate(QObject *parent = 0);
  8. 	~MyDelegate() {}
  9.  
  10. 	void paint(QPainter *painter, const QStyleOptionViewItem &option,
  11. 		const QModelIndex &index) const;
  12. 	QSize sizeHint(const QStyleOptionViewItem &option,
  13. 		const QModelIndex &index) const;
  14. 	QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option,
  15. 		const QModelIndex &index) const;
  16. 	void setEditorData(QWidget *editor, const QModelIndex &index) const;
  17. 	void setModelData(QWidget *editor, QAbstractItemModel *model,
  18. 		const QModelIndex &index) const;
  19.  
  20. 	private slots:
  21. 		void commitAndCloseEditor();
  22. };
