QTableView

Just connect the signal with a slot in PrincipalFrm and do what you're doing in on_tableView_clicked()

Hi, you know I did what you said, but when I want to connect the currentChanged signal, it just does not appear, which is what I'm doing wrong.

QObject::connect(ui->tableView, &QTableView::    ,this,[&](){

      QMessageBox::information(this,qApp->applicationName(),"Mensaje");
    });

Hi,

Do you mean there's no auto-completion ? If so, that shouldn't stop you, write the name of the signal. If you make any mistake in it, the compilation will fail.

lincoln

the problem is not the auto completed, the problem is that the currentChanged () signal does not appear, when putting the four points, only one eslot appears and a function with the same name of the signal.

SGaist

Well, that sounds like the auto-complete feature malfunctioning. But again, that's just a helper. Write the signal name and go on with your application.

Well, what I can say is that I have not achieved anything yet, and the truth is that I'm tired of searching and not getting an answer, thanks anyway.

@lincoln Did you try to write

QObject::connect(ui->tableView, &QTableView::currentChanged, this,[&](){

      QMessageBox::information(this,qApp->applicationName(),"Mensaje");
    });

?
There is nothing to search, you just need to write what was already suggested...

QMessageBox::information(this,qApp->applicationName(),"Mensaje");

I already did that and when I do I get this error.

QAbstractItemView::currentChanged()

Ah, you have to go through the selectionModel, sorry

connect(ui->tableView->selectionModel, &QItemSelectionModel::currentChanged, ...)
