incomplete type ? (error)

[noborder]

I have slot:

void Image::imagechange(QStringList filelist) // error: 'filelist' has incomplete type.
{
    qDebug() << "imagechange";
    QString imagepath;;
    emit signal_show_image(imagepath);
}

void Image::imagechange(QStringList filelist) // error: 'filelist' has incomplete type.
{
    qDebug() << "imagechange";
    QString imagepath;;
    emit signal_show_image(imagepath);
}

You must put somewhere this line

#include <QStringList>
