I have a KDE/Qt3 source code and i want to port it to KDE/Qt4, but i don't know how to implement my
style without QStyleSheet. I have a class derived from QTextBrowser with this code in the
constructor, in order to add some tags to QStyleSheet used by QTextBrowser:

//*******************************************************************************
CNavTB::CNavTB(QWidget *parent, const char *name) : QTextBrowser (parent, name) {
  QStyleSheet *ss = new QStyleSheet(this, "HojaDeEstilos_CWBiblias");
  QStyleSheetItem *qssi = new QStyleSheetItem(ss, "bbi");
  qssi->setAnchor(TRUE);
  qssi->setColor("#996633");
  qssi->setFontWeight(QFont::Bold);
  qssi->setLogicalFontSize(4);
  qssi->setVerticalAlignment(QStyleSheetItem::VAlignSuper);

  qssi = new QStyleSheetItem(ss, "bbn");
  qssi->setAnchor(TRUE);
  qssi->setColor("#6699CC");
  qssi->setFontWeight(QFont::Bold);
  qssi->setLogicalFontSize(4);
  qssi->setVerticalAlignment(QStyleSheetItem::VAlignSuper);

  qssi = new QStyleSheetItem(ss, "num");
  qssi->setColor("#800000");
  qssi->setLogicalFontSize(3);
  qssi->setVerticalAlignment(QStyleSheetItem::VAlignSuper);

  qssi = new QStyleSheetItem(ss, "ver");
  qssi->setColor("#000000");
  qssi->setFontWeight(QFont::Normal);
  qssi->setLogicalFontSize(3);
  qssi->setDisplayMode(QStyleSheetItem::DisplayBlock);
  qssi->setSelfNesting(FALSE);
  setStyleSheet(ss);
  setPaletteBackgroundColor("#FFFFFF");
  setLinkUnderline(FALSE);
  connect(this, SIGNAL(linkClicked(const QString&)), this, SLOT(slotLinkClicked(const QString&)));
}
//*******************************************************************************


Then, when i use this class for showing some text, i set the html text with my tags:


//*******************************************************************************
  ListaTB = new CNavTB(this);
  QString V = "<table width=100%>";
  CAP C = LeeC(Cap);
  for (CAP::iterator it = C.begin(); it != C.end(); it++, NumV++) {
    V += "<tr><td bgcolor=#";
    V += (NumV & 1 ? "FFFFFF>" : "F6F6F6>");
    V += "<bbi name=#" + QString::number(NumV) + "></bbi><ver><num>" + QString::number(NumV) +
"</num> " + QString::fromUtf8((*it).c_str());
    V += " <bbi href=#V" + QString::number(Cap) + "_" + QString::number(NumV - 1) +
            "-" + QString::number(NumV) + ">&#167;</bbi><bbn href=#N0_0-0>&#182;</bbn></ver></td></tr>";
  }
  V += "</table>";
  ListaTB->setTexto(V);
//*******************************************************************************

How is the way for this using KDE/Qt4?
I need to format my text using my own tags.

I have read some articles from Trolltech about QTextDocument and QTextCursor but i don't understand
them and don't have examples similar to my situation.

Regards

Joaquín
