Problem connecting selectionChanged

[jano_alex_es]

Hi, I want to connect QAbstractItemView::selectionChanged, but I don't know why it's not working :S

m_itemSelectedModel = ui.m_myTableView->selectionModel();
bool test = QObject::connect(m_itemSelectedModel , SIGNAL(selectionChanged()), this, SLOT(my_private_slot()));

m_itemSelectedModel = ui.m_myTableView->selectionModel();
bool test = QObject::connect(m_itemSelectedModel , SIGNAL(selectionChanged()), this, SLOT(my_private_slot()));

To copy to clipboard, switch view to plain text mode 

thanks!
