How to print a QTableView

Hi,

I would like to print a table which contains text only. I search through the forum and found this piece of code

Code:

---

QPainter painter(printer);
    const QRect area = printer->pageRect();
    const int rows = m_data_model.rowCount();
    const int cols = m_data_model.columnCount();
 
    // calculate the total width/height table would need without scaling
    double totalWidth = 0.0;
    for (int c = 0; c < cols; ++c)
    {
        totalWidth += columnWidth(c);
    }
    double totalHeight = 0.0;
    for (int r = 0; r < rows; ++r)
    {
        totalHeight += rowHeight(r);
    }
 
    // paint cells
    for (int r = 0; r < rows; ++r)
    {
        for (int c = 0; c < cols; ++c)
        {
            QModelIndex idx = m_data_model.index(r, c);
            QStyleOptionViewItem option = viewOptions();
            option.rect = visualRect(idx);
            itemDelegate()->paint(&painter, option, idx);
        }
    }

---

However, the code does not print the table's vertical and horizontal headers, as well as the grid lines. How can I print a table, with both the headers and the grid lines?

I am using Qt4.4.

Thanks.

Now, I am able to print the horizontal header with the code below:

Code:

---

const int horizontal_height = horizontalHeader()->height();
const int vertical_width = verticalHeader()->width();
int width = horizontal_header_rect.size().width();
 
QWidget *view_port = horizontalHeader()->viewport();
QPixmap horizontal_pixmap(width, horizontal_height);	
QPaintEvent paint_horizontal_event(horizontal_header_rect);	
dc->setRedirected(view_port, &horizontal_pixmap);    
QApplication::sendEvent(view_port, &paint_horizontal_event);
dc->restoreRedirected(view_port);
dc->drawPixmap(printer->pageRect().topLeft() + QPoint(vertical_width, 0), horizontal_pixmap, horizontal_header_rect);

---

It could print nicely but, I still face a problem if the header is larger than the paper size. For example, I have a table with 33 columns. I could print nicely the header for the first 20 columns in first page, but fails to print for the remaining 13 columns in second page.

How could I modify the code to print the header nicely for the second page and all subsequent pages? Could any gurus out there helps?

Thanks.
