Setting QTreeWidget flag to Qt::ItemIsEditable seems to disable itemActivated SIGNAL

[y.shan]

I've summarized the problem in a small demonstration: If I set the ItemIsEditable flag then the itemActivated signal is not triggered on double clicking. Else it works fine.

Window::Window()
{
	treeWidget = new QTreeWidget();
 
	QStringList list;
	list << "";
 
	QTreeWidgetItem * treeWidgetItem = new QTreeWidgetItem(treeWidget, list);
 
	//setting this flag disables itemActivated signal for double clicking
	treeWidgetItem->setFlags(treeWidgetItem->flags()|Qt::ItemIsEditable);
 
	treeWidget->insertTopLevelItem(0, treeWidgetItem);
 
	connect(treeWidget, SIGNAL(itemActivated(QTreeWidgetItem*, int)),
			this, SLOT(treeWidgetItemActivated(QTreeWidgetItem*, int)));
 
	QGridLayout * layout = new QGridLayout;
	layout->addWidget(treeWidget);
 
	setLayout(layout);
}
 
void Window::treeWidgetItemActivated(QTreeWidgetItem * item, int column)
{
	QMessageBox::information(this, "", "itemActivated triggered");
}

Window::Window()
{
	treeWidget = new QTreeWidget();

	QStringList list;
	list << "";

	QTreeWidgetItem * treeWidgetItem = new QTreeWidgetItem(treeWidget, list);

	//setting this flag disables itemActivated signal for double clicking
	treeWidgetItem->setFlags(treeWidgetItem->flags()|Qt::ItemIsEditable);

	treeWidget->insertTopLevelItem(0, treeWidgetItem);

	connect(treeWidget, SIGNAL(itemActivated(QTreeWidgetItem*, int)),
			this, SLOT(treeWidgetItemActivated(QTreeWidgetItem*, int)));

	QGridLayout * layout = new QGridLayout;
	layout->addWidget(treeWidget);

	setLayout(layout);
}

void Window::treeWidgetItemActivated(QTreeWidgetItem * item, int column)
{
	QMessageBox::information(this, "", "itemActivated triggered");
}
