QTableWidget how could I detect is a cell is editing??

Hello,

I would like to detect when a cell is editing or just start edit.

At this moment, I could known when end edit with this code

Code:

---

itemDelegate = new QItemDelegate();
	connect(itemDelegate, SIGNAL(closeEditor(QWidget*)), this, SLOT(execute()));
	ui.table->setItemDelegateForColumn(4, itemDelegate);

---

But I dont find how could I deteted when user star edit a cell.
any advice??

Thank you in advance.

createEditor() on the delegate is called and then setEditorData() is called.
