blockingMap: no matching function for call to `(QList<QString>&, <unknown type>)`

[qweide]

Hi guys,

I am trying to use the Thread functions like in the map example.

I needed the scale function to access the ui, so I changed it in the cpp file to this:

QString MainWindow::scale(const QString &filename)
{
   ...
}

QString MainWindow::scale(const QString &filename)
{
   ...
}

To copy to clipboard, switch view to plain text mode 

This appearently required me to add it to the header file. I did it like this:

...
public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();
    QString scale(const QString &filename);
...

...
public:
    MainWindow(QWidget *parent = 0);
    ~MainWindow();
    QString scale(const QString &filename);
...

To copy to clipboard, switch view to plain text mode 

The call remains

QtConcurrent::blockingMapped(images, scale);

QtConcurrent::blockingMapped(images, scale);

To copy to clipboard, switch view to plain text mode 

The error message I receive is:

mainwindow.cpp:85: error: no matching function for call to `blockingMapped(QList<QString>&, <unknown type>)'

Why doesn't he recognize the function anymore?

Any help is greatly appreciated .
