C++ GUI Programming with Qt 4:the coordinate setter application

[adonis]

Hi everybody,:)
i am a newbie and i am interested in the Coordinate Setter application in Chapter10 of Blanchette ´s book.In the book there is only a part of the code ,and i dont know how to make it work.

This what i found in the book.what should i add to make it work?


CoordinateSetter::CoordinateSetter(QList<QPointF> *coords,
QWidget *parent)
: QDialog(parent)
{
coordinates = coords;
tableWidget = new QTableWidget(0, 2);
tableWidget->setHorizontalHeaderLabels(
QStringList() << tr("X") << tr("Y"));
for (int row = 0; row < coordinates->count(); ++row) {
QPointF point = coordinates->at(row);
addRow();
tableWidget->item(row, 0)->setText(QString::number(point.x()));
tableWidget->item(row, 1)->setText(QString::number(point.y()));
}
...
}


void CoordinateSetter::addRow()
{
int row = tableWidget->rowCount();
tableWidget->insertRow(row);
QTableWidgetItem *item0 = new QTableWidgetItem;
item0->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter);
tableWidget->setItem(row, 0, item0);
QTableWidgetItem *item1 = new QTableWidgetItem;
item1->setTextAlignment(Qt::AlignRight | Qt::AlignVCenter);
tableWidget->setItem(row, 1, item1);
tableWidget->setCurrentItem(item0);
}

void CoordinateSetter::done(int result)
{
if (result == QDialog::Accepted) {
coordinates->clear();
for (int row = 0; row < tableWidget->rowCount(); ++row) {
double x = tableWidget->item(row, 0)->text().toDouble();
double y = tableWidget->item(row, 1)->text().toDouble();
coordinates->append(QPointF(x, y));
}
}
QDialog::done(result);
}
:confused:

As far as I know all the examples are provided in the enclosed CD.
The all should compile with out a problem.
