Here is an example of how you can get a table cell's text when clicking on it.

Suppose a QTableView defined in some MyClass class. You need to connect the clicked signal to your own MyClass::onTableClicked() slot, as shown below:

connect(tableView, SIGNAL(clicked(const QModelIndex &)), this, SLOT(onTableClicked(const QModelIndex &)));

注意：QT的connect只写参数类型，不写参数名。

Slot implementation:

void MyClass::onTableClicked(const QModelIndex &index) { if (index.isValid()) { QString cellText = index.data().toString(); } }

You can use also doubleClicked, pressed or other signals depending on your goal.
