Question

I have in my main window 2 triggers
1. from the menu that closed totaly the app
2. from he window X button that ignored and just hide the window.
I’m using this SIGNAL/SLOTS
how can I know from where is it being triggered?.

In the closeEvent:

connect(ui->actionQuit, SIGNAL(triggered()),this, SLOT(CloseWin()));

void MainWindow::CloseWin()
{

   close();

}
// triggered from the ui->actionQuit amd from the X button

void MainWindow::closeEvent(QCloseEvent *event)
{

    // how can i know from where its bean triggered?     
    hide();
        event->ignore();

}

Two solutions are possible:

1. connect menu item (QAction) signal to a separate slot and call qApp->quit() there
2. use sender() method inside your slot to determine the object which sent the signal

I would prefer first one.
