Функция автозаполнения для QLineEdit, не могу разобраться с слотами Опции

[FladeX]

Не получается разобраться с слотом для автоматического заполнения полей.
Имеется следующий код, реализующий простенькую форму с 5 QLabel, 5 QLineEdit и 3 QPushButton:

#include <QApplication>
#include <QMainWindow>
#include <QWidget>
#include <QLabel>
#include <QLineEdit>
#include <QPushButton>
#include <QGridLayout>
#include <QVBoxLayout>

class MyWidget : public QWidget
{
public:
    MyWidget(QWidget *parent = 0);
public slots:
    void setValue();
};

MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
    QVBoxLayout *layout = new QVBoxLayout;
    QGridLayout *grid = new QGridLayout;

    QLabel *x1label = new QLabel(tr("x1="));
    QLabel *y1label = new QLabel(tr("y1="));
    QLabel *x2label = new QLabel(tr("x2="));
    QLabel *y2label = new QLabel(tr("y2="));
    QLabel *slabel = new QLabel(tr("S="));

    QLineEdit *x1edit = new QLineEdit;
    QLineEdit *y1edit = new QLineEdit;
    QLineEdit *x2edit = new QLineEdit;
    QLineEdit *y2edit = new QLineEdit;
    QLineEdit *sedit = new QLineEdit;

    QPushButton *automode = new QPushButton(tr("Auto"));
    QPushButton *resetmode = new QPushButton(tr("Reset"));
    QPushButton *gomode = new QPushButton(tr("Go!"));

    grid->addWidget(x1label, 0, 0);
    grid->addWidget(y1label, 1, 0);
    grid->addWidget(x2label, 2, 0);
    grid->addWidget(y2label, 3, 0);
    grid->addWidget(slabel, 4, 0);

    grid->addWidget(x1edit, 0, 1);
    grid->addWidget(y1edit, 1, 1);
    grid->addWidget(x2edit, 2, 1);
    grid->addWidget(y2edit, 3, 1);
    grid->addWidget(sedit, 4, 1);

    grid->addWidget(automode, 5, 1);
    grid->addWidget(resetmode, 6, 1);
    grid->addWidget(gomode, 7, 1);

    layout->addLayout(grid);
    setLayout(layout);

    connect(resetmode, SIGNAL(clicked()), x1edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), y1edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), x2edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), y2edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), sedit, SLOT(clear()));

    connect(automode, SIGNAL(clicked()), x1edit, SLOT(setValue()));
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    MyWidget widget;
    widget.show();
    return app.exec();
}

Мне нужно сделать автозаполнение всех 5 QLineEdit при нажатии на automode. Я добавил connect, но с описанием слота, а точнее функции setValue() возникли затруднения. Подскажите плиз, как надо сделать.

Нет..
На одном форуме вроде подсказали как надо, но все равно не до конца.. Сейчас пытаюсь доделать тот вариант.
Собираю

qmake -project
qmake
make

Ошибки... Каждый раз разные. запутался в конец..

Код:

#include <QApplication>
#include <QMainWindow>
#include <QWidget>
#include <QLabel>
#include <QLineEdit>
#include <QPushButton>
#include <QGridLayout>
#include <QVBoxLayout>
#include <main.moc>

class MyWidget : public QWidget
    Q_OBJECT
{
public:
    MyWidget(QWidget *parent = 0);
//
private:
    QLineEdit *x1edit;
//
public slots:
    void setValue();
};

void MyWidget::setValue()
{
    x1edit->setText("123");
};

MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
    QVBoxLayout *layout = new QVBoxLayout;
    QGridLayout *grid = new QGridLayout;

    QLabel *x1label = new QLabel(tr("x1="));
    QLabel *y1label = new QLabel(tr("y1="));
    QLabel *x2label = new QLabel(tr("x2="));
    QLabel *y2label = new QLabel(tr("y2="));
    QLabel *slabel = new QLabel(tr("S="));

    x1edit = new QLineEdit;
    QLineEdit *y1edit = new QLineEdit;
    QLineEdit *x2edit = new QLineEdit;
    QLineEdit *y2edit = new QLineEdit;
    QLineEdit *sedit = new QLineEdit;

    QPushButton *automode = new QPushButton(tr("Auto"));
    QPushButton *resetmode = new QPushButton(tr("Reset"));
    QPushButton *gomode = new QPushButton(tr("Go!"));

    grid->addWidget(x1label, 0, 0);
    grid->addWidget(y1label, 1, 0);
    grid->addWidget(x2label, 2, 0);
    grid->addWidget(y2label, 3, 0);
    grid->addWidget(slabel, 4, 0);

    grid->addWidget(x1edit, 0, 1);
    grid->addWidget(y1edit, 1, 1);
    grid->addWidget(x2edit, 2, 1);
    grid->addWidget(y2edit, 3, 1);
    grid->addWidget(sedit, 4, 1);

    grid->addWidget(automode, 5, 1);
    grid->addWidget(resetmode, 6, 1);
    grid->addWidget(gomode, 7, 1);

    layout->addLayout(grid);
    setLayout(layout);

    connect(resetmode, SIGNAL(clicked()), x1edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), y1edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), x2edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), y2edit, SLOT(clear()));
    connect(resetmode, SIGNAL(clicked()), sedit, SLOT(clear()));

    connect(automode, SIGNAL(clicked()), this, SLOT(setValue()));
}

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    MyWidget widget;
    widget.show();
    return app.exec();
}
