Export a QTableWidget in PDF

fermatqt

hi!

I should export the data of a QTableWidget in PDF.
I do not print the widget, I have to export all the data.
do you have any suggestions?

One way is to use the QPdfWriter class, here
I guess you must daw onto the pages yourself with this.

Might be easier to use a QPrinter with the output format set to QPrinter::PdfFormat.
Then there is QTextDocument which you could use to format your data and then print that to a pdf.
I am sure other people will suggest other things.

ok, I tried with this:

            QPrinter printer(QPrinter::PrinterResolution);
            printer.setOutputFormat(QPrinter::PdfFormat);
            printer.setPaperSize(QPrinter::A4);
            printer.setOrientation(QPrinter::Landscape);
            printer.setOutputFileName(strFile);

            QTextDocument doc;
            QString style("<style>");
            style.append("table { border-collapse: collapse;font-size:10px; }");
            style.append("table, th, td { border: 1px solid black;text-align: left; }");
            //style.append("th, td { border: 1px solid black;text-align: left; }");
            style.append("</style>");

            QString text("<table><thead>");
            text.append("<tr>");
            for (int i = 0; i < tbl->columnCount(); i++) {
                text.append("<th>").append(tbl->horizontalHeaderItem(i)->data(Qt::DisplayRole).toString()).append("</th>");
            }
            text.append("</tr></thead>");
            text.append("<tbody>");
            for (int i = 0; i < tbl->rowCount(); i++) {
                text.append("<tr>");
                for (int j = 0; j < tbl->columnCount(); j++) {
                    QTableWidgetItem *item = tbl->item(i, j);
                    if (!item || item->text().isEmpty()) {
                        tbl->setItem(i, j, new QTableWidgetItem("0"));
                    }
                    text.append("<td>").append(tbl->item(i, j)->text()).append("</td>");
                }
                text.append("</tr>");
            }
            text.append("</tbody></table>");
            doc.setDefaultStyleSheet(style);
            doc.setHtml(text);
            doc.setPageSize(printer.pageRect().size());
            doc.print(&printer);

the table in the pdf is created, but the style is not applied!

what about QTextTable ?

what about QTextTable ?

ok I'm trying with QTextTable:

const int columns = tbl->columnCount();
            const int rows = tbl->rowCount();
            QTextDocument doc;
            QTextCursor cursor(&doc);
            QTextTableFormat tableFormat;
            tableFormat.setHeaderRowCount(1);
            tableFormat.setAlignment(Qt::AlignHCenter);
            tableFormat.setCellPadding(0);
            tableFormat.setCellSpacing(0);
            tableFormat.setBorder(1);
            tableFormat.setBorderBrush(QBrush(Qt::SolidPattern));
            tableFormat.clearColumnWidthConstraints();
            QTextTable *textTable = cursor.insertTable(rows + 1, columns, tableFormat);
            QTextCharFormat tableHeaderFormat;
            tableHeaderFormat.setBackground(QColor("#DADADA"));
            for (int i = 0; i < columns; i++) {
                QTextTableCell cell = textTable->cellAt(0, i);
                cell.setFormat(tableHeaderFormat);
                QTextCursor cellCursor = cell.firstCursorPosition();
                cellCursor.insertText(tbl->horizontalHeaderItem(i)->data(Qt::DisplayRole).toString());
            }
            for (int i = 0; i < rows; i++) {
                for (int j = 0; j < columns; j++) {
                    QTableWidgetItem *item = tbl->item(i, j);
                    if (!item || item->text().isEmpty()) {
                        tbl->setItem(i, j, new QTableWidgetItem("0"));
                    }

                    QTextTableCell cell = textTable->cellAt(i, j);
                    QTextCursor cellCursor = cell.firstCursorPosition();
                    cellCursor.insertText(tbl->item(i, j)->text());
                }
            }
            cursor.movePosition(QTextCursor::End);
            QPrinter printer(QPrinter::PrinterResolution);
            printer.setOutputFormat(QPrinter::PdfFormat);
            printer.setPaperSize(QPrinter::A4);
            printer.setOrientation(QPrinter::Landscape);
            printer.setOutputFileName(strFile);
            doc.setDocumentMargin(0);
            doc.setTextWidth(5);
            doc.print(&printer);

the only problem I have is that I do not see the table header.
It is overwritten by the first row of data set.

ok, I did in this way and works:

QTextTableCell cell = textTable->cellAt(i + 1, j);

thanks a lot!!!

Glad you were able to get it working :-)

Maybe you could set your post to SOLVED now so other people will find the solution.
