http://ciz.ch/svnciz/_STATIC_LIBS_QT.../html_edit.cpp

this sample make a href link or unlink a text

Qt Code: 
  1. void HTML_Edit::makehrefLink()
  2. {
  3.     bool is_selected = html_area->textCursor().hasSelection();
  4.     QString sthtml = html_area->textCursor().selectedText();
  5.     if (vol_18->isChecked()) {
  6.         QString ltext;
  7.          if (sthtml.size() < 1) {
  8.            sthtml= "Text to link";  
  9.          }
  10.          Href_Gui::self( this )->text_href->setText(sthtml);
  11.          Href_Gui::self( this )->exec();
  12.          if (Href_Gui::self) {
  13.               QStringList data = Href_Gui::_self->GetUserConfig();
  14.                if (data.count() > 0) {
  15.                /*qDebug() << "### linerr rrr   " << QString(data.at(0));
  16.                qDebug() << "### linerr rrr   " << QString(data.at(1));
  17.                qDebug() << "### linerr rrr   " << QString(data.at(2));*/
  18.                 ltext ="<a href=\""+QString(data.at(1))+"#target="+QString(data.at(2))+"\">"+QString(data.at(0))+"</a>";
  19.                 QTextDocumentFragment fragment = QTextDocumentFragment::fromHtml(ltext);
  20.                 html_area->textCursor().insertFragment(fragment); 
  21.                 vol_18->setChecked(false);
  22.                 }
  23.           }
  24.     } else {
  25.         QTextDocumentFragment fragment = QTextDocumentFragment::fromHtml(sthtml);
  26.         html_area->textCursor().insertFragment(fragment);     
  27.     }
  28.
