How do I print QStringListModel content? - c++

Question

I need to print the content of a QStringListModel to a printer, in 'void MainWindow::on_pbImprime_clicked()' It's printing any Qstring with no problems, but I don't know how to put the data of QStringListModel to my QString text, anyone have an idea?
Here is my code:
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
model = new QStringListModel(this);
ui->lbItens->setModel(model);
ui->lbItens->setEditTriggers(QAbstractItemView::AnyKeyPressed |
QAbstractItemView::DoubleClicked);
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::on_pbAdd_clicked()
{
int row = model->rowCount();
model->insertRows(row,1);
QModelIndex index = model->index(row);
ui->lbItens->setCurrentIndex(index);
ui->lbItens->edit(index);
}
void MainWindow::on_pbRemove_clicked()
{
model->removeRows(ui->lbItens->currentIndex().row(),1);
}
void MainWindow::on_pbImprime_clicked()
{
QPrinter printer;
QPainter p(&printer);
int x_pos = 20;
int y_pos = 20;
int row = model->rowCount();
int i;
for(i=0; i<row; i++){
QString text = ;
p.drawText(x_pos, y_pos, text);
y_pos += p.fontMetrics().height();
}
}
Sorry for my bad english and thanks for the help.

Answer 1

You can get QStringList from your model:
QStringList list = model->stringList();
From QStringList get your QString using join():
QString str = list.join(" ");
In join you may choose separator you need.

Answer 2

Alternatively, you can try this
void MainWindow::on_pbImprime_clicked()
{
QPrinter printer;
...
for(i=0; i<row; i++){
QString text = model->data(model->index(row, 0)).toString();
p.drawText(x_pos, y_pos, text);
y_pos += p.fontMetrics().height();
}
}
As a matter of fact,
QVariant QAbstractItemModel::data(const QModelIndex & index, int role = Qt::DisplayRole) const
is the prefered way to get data out of model.
