how to launch a wizard from the mainwindow's File Menu

[wysota]

So i did this:

void MainWindow::newFile()
{
 
 
    SkoolCalcWizard wizard;
    wizard.show();
 
 
}

void MainWindow::newFile()
{
    

    SkoolCalcWizard wizard;
    wizard.show();


}

To copy to clipboard, switch view to plain text mode 

But then the program runs and does the same thing as above, it immediately exits once i click on the New action.

You create a local variable that goes out of scope once the function ends. While exec() is a blocking call that doesn't return until the dialog is closed, show() behaves differently -- it schedules an event to show the widget and returns immediately.
