A Bug in Qt?

[spirit]

try to use something like this

...
connect(ui.tableView, SIGNAL(entered(const QModelIndex &)), SLOT(entered(const QModelIndex &)));
 
}
 
void MyWidget::entered(const QModelIndex &index)
{
     if (!index.isValid())
            return;
     ui.lineEdit->setText(QString("%1").arg(m_selectionModel->selectedRows().size()));
}

...
connect(ui.tableView, SIGNAL(entered(const QModelIndex &)), SLOT(entered(const QModelIndex &)));

}

void MyWidget::entered(const QModelIndex &index)
{
     if (!index.isValid())
            return;
     ui.lineEdit->setText(QString("%1").arg(m_selectionModel->selectedRows().size()));
}

To copy to clipboard, switch view to plain text mode

And the signal does not meet the logic demand.

this code returs correct value of selected rows. maybe you do something wrong or I don't understand properly what do you want to achieve.
