For QTableWidget, what's the difference of cellChanged and itemChanged?

Doc for the 2 signals

• cellChanged
  This signal is emitted whenever the data of the item in the cell specified by row and column has changed.
  This function was introduced in Qt 4.1.
• itemChanged
  This signal is emitted whenever the data of item has changed.

It seems that they are same, except itemChanged is newer than cellChanged and more convenient. Right?

Hi,

cellChanged is for all QAbstractItemView classes, itemChanged is specific to the convenience views (QListWidget, QTableWidget, QTreeWidget) where you use the corresponding item classes to interact with the model.

@jronald
QTableView has no cellChanged.

QTableView has no cellChanged.

Sorry it should be QTableWidget.
