QTableView printing
Here is a variation of the first answer that gets rid of the intermediate file.
QString strStream;
QTextStream out(&strStream);
const int rowCount = pPublic->tableView->model()->rowCount();
const int columnCount = pPublic->tableView->model()->columnCount();
out << "<html>\n"
"<head>\n"
"<meta Content=\"Text/html; charset=Windows-1251\">\n"
<< QString("<title>%1</title>\n").arg(strTitle)
<< "</head>\n"
"<body bgcolor=#ffffff link=#5000A0>\n"
"<table border=1 cellspacing=0 cellpadding=2>\n";
// headers
out << "<thead><tr bgcolor=#f0f0f0>";
for (int column = 0; column < columnCount; column++)
if (!pPublic->tableView->isColumnHidden(column))
out << QString("<th>%1</th>").arg(pPublic->tableView->model()->headerData(column, Qt::Horizontal).toString());
out << "</tr></thead>\n";
// data table
for (int row = 0; row < rowCount; row++) {
out << "<tr>";
for (int column = 0; column < columnCount; column++) {
if (!pPublic->tableView->isColumnHidden(column)) {
QString data = pPublic->tableView->model()->data(pPublic->tableView->model()->index(row, column)).toString().simplified();
out << QString("<td bkcolor=0>%1</td>").arg((!data.isEmpty()) ? data : QString(" "));
}
}
out << "</tr>\n";
}
out << "</table>\n"
"</body>\n"
"</html>\n";
QTextDocument *document = new QTextDocument();
document->setHtml(strStream);
QPrinter printer;
QPrintDialog *dialog = new QPrintDialog(&printer, NULL);
if (dialog->exec() == QDialog::Accepted) {
document->print(&printer);
}
delete document;
here is my solution of a problem. May be it's too complex... But here you could find more solutions!
1). first I have saved table data to HTML page file:
bool CRefViewerDlg::createHtmlTableFromModel() {
// make a html-dump of table view
if (tableView) {
const QString htmlFileName = QString("%1/%2").arg(qApp->applicationDirPath()).arg("myTable.html");
QFile file(htmlFileName);
if (!file.open(QIODevice::WriteOnly | QIODevice::Text)) {
MSG(QString("Can`t create file %1").arg(htmlFileName));
return false;
}
QTextStream out(&file);
const xbLong rowCount = tableView->model()->rowCount();
const xbLong columnCount = tableView->model()->columnCount();
out << "<html>\n"
"<head>\n"
"<meta Content=\"Text/html; charset=Windows-1251\">\n"
<< QString("<title>%1</title>\n").arg(refTitleName)
<< "</head>\n"
"<body bgcolor=#ffffff link=#5000A0>\n"
"<table border=1 cellspacing=0 cellpadding=2>\n";
// headers
out << "<tr bgcolor=#f0f0f0>";
for (xbLong column = 0; column < columnCount; column++)
if (!tableView->isColumnHidden(column))
out << QString("<th>%1</th>").arg(tableView->model()->headerData(column, Qt::Horizontal).toString());
out << "</tr>\n";
file.flush();
// data table
for (xbLong row = 0; row < rowCount; row++) {
out << "<tr>";
for (xbLong column = 0; column < columnCount; column++) {
if (!tableView->isColumnHidden(column)) {
QString data = tableView->model()->data(tableView->model()->index(row, column)).toString().simplified();
out << QString("<td bkcolor=0>%1</td>").arg((!data.isEmpty()) ? data : QString(" "));
}
}
out << "</tr>\n";
}
out << "</table>\n"
"</body>\n"
"</html>\n";
file.close();
}
return true;
}
2). after I have saved html content to file, it was opened in html view window, where I could print the document with QTextBrowser
class:
void CLiveListDlg::on_printPageToolButton_clicked() {
#ifndef QT_NO_PRINTER
QTextBrowser *editor = static_cast<QTextBrowser* >(textBrowser);
QPrinter printer;
QPrintDialog *dialog = new QPrintDialog(&printer, this);
dialog->setWindowTitle(tr("Print Document"));
if (editor->textCursor().hasSelection())
dialog->addEnabledOption(QAbstractPrintDialog::PrintSelection);
if (dialog->exec() != QDialog::Accepted)
return;
editor->print(&printer);
#endif
}
