Question

I am trying to print a table view. To fill a table view I have created my own model. To print table I am doing following:

QPrinter printer;
QPrintDialog printDialog( &printer, 0);
if( QDialog::Accepted == printDialog.exec() ) {

    if( QPrinter::Landscape != printer.orientation() ) {
        printer.setOrientation(QPrinter::Landscape);
    }

    QPoint startPoint = QPoint(20, 20);
    QRegion printRegion = QRegion( 20, 20, printer.paperRect().width(),printer.paperRect().height() );
    for( int i = 0; i < m_tables.size(); ++i ) {
        tableView->render( &printer, startPoint, printRegion, QWidget::DrawChildren );
    }
}

The issue is that I am printing into PDF file and there I am able to see only a small part of the table. I thought that changing the region parameter could help, but in the fact not. Any suggestions how to fix this?

Ok, here is my solution. Would be nice to hear your opinion.

PrintTableModel* pTableModel = new PrintTableModel();

QTableView* pTableView = new QTableView;
pTableView->setModel(pTableModel);

int width = 0;
int height = 0;
int columns = pTableModel->columnCount();
int rows = pTableModel->rowCount();

pTableView->resizeColumnsToContents();

for( int i = 0; i < columns; ++i ) {
    width += pTableView->columnWidth(i);
}

for( int i = 0; i < rows; ++i ) {
    height += pTableView->rowHeight(i);
}

pTableView->setFixedSize(width, height);
pTableView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff);
pTableView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff);

This code helped me. To print the table correctly, you just can perform a render call:

pTableView->render(printer);
