Calc example throwing errors when I try it on my own

[TomJoad]

I need help as I have no idea what I could be doing wrong. I have been trying to follow the Calc Form Example (http://doc.trolltech.com/4.7/designe...latorform.html) and can't for the life of me figure out what I am doing wrong.

Here are the error codes that are thrown when trying to compile:

..\test\widget.cpp: In member function 'void Widget::on_def_valueChanged(int)':
..\test\widget.cpp:17: error: request for member 'total' in '((Widget*)this)->Widget::ui', which is of non-class type 'Ui::Widget*'
..\test\widget.cpp:17: error: request for member 'soc' in '((Widget*)this)->Widget::ui', which is of non-class type 'Ui::Widget*'

..\test\widget.cpp: In member function 'void Widget::on_def_valueChanged(int)':
..\test\widget.cpp:17: error: request for member 'total' in '((Widget*)this)->Widget::ui', which is of non-class type 'Ui::Widget*'
..\test\widget.cpp:17: error: request for member 'soc' in '((Widget*)this)->Widget::ui', which is of non-class type 'Ui::Widget*'

Here is widget.cpp:

#include "widget.h"
 
Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);
}
 
Widget::~Widget()
{
    delete ui;
}
 
void Widget::on_def_valueChanged(int value)
{
    ui.total->setText(QString::number(value * 2 + ui.soc->value()));
}

#include "widget.h"

Widget::Widget(QWidget *parent) :
    QWidget(parent),
    ui(new Ui::Widget)
{
    ui->setupUi(this);
}

Widget::~Widget()
{
    delete ui;
}

void Widget::on_def_valueChanged(int value)
{
    ui.total->setText(QString::number(value * 2 + ui.soc->value()));
}

main.cpp:

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();
 
    return a.exec();
}

#include <QtGui/QApplication>
#include "widget.h"

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();

    return a.exec();
}

"def" and "soc" are qspinboxs, and "total" is a qlabel.

This should be simple, right? I'm sitting here banging my head against the wall.
