QTextFrame::iterator richtext QTextDocument problem?

[patrik08]

I spend two day to dispay and edit the XSL-Fo format is similar from dock book KDE..
now i can not grab QTextDocument to resave to xml file. :mad:
Question:
Why QTextFrame can not find image or table? inside a QTextFrame::iterator from QTextDocument

Or is image part from fragment? how grab this?

i have one image and one table inside and iterator not find? why .. pleas help .
I not found any sample to iterate QTextDocument http://doc.trolltech.com/4.2/richtext-structure.html





//////QTextDocument *w3 = fop.GetDoc() [ return QTextDocument->clone() ] XSL-FO format ;
/////QTextFrame *Tframe = w3->rootFrame();

int speed = 0;
qDebug() << "### iterator start ############################" << speed;

/* QTextFrameFormat QTextFrame::frameFormat() const */

QTextFrame::iterator it;
for (it = Tframe->begin(); !(it.atEnd()); ++it) {
speed++; /* to find tree structure */
QTextFrame *childFrame = it.currentFrame();
QTextBlock para = it.currentBlock();

if (childFrame) {
qDebug() << "### frame " << speed;

} else if (para.isValid()) {
qDebug() << "### block " << speed << " Paragraph ->" << para.text();

if (para.charFormat().isValid()) { /* QTextCharFormat */
QTextCharFormat subpara = para.charFormat();

qDebug() << "### inline span " << speed;

if ( subpara.toImageFormat().isValid() ) {

QTextImageFormat Pic = subpara.toImageFormat();
qDebug() << "### image " << speed;

} else if ( subpara.toTableFormat().isValid() ) {

QTextTableFormat Ta = subpara.toTableFormat();
qDebug() << "### table " << speed;
}



}



}
}
qDebug() << "### iterator end ############################" << speed;

i found now a QTextBlock::iterator ... from qt4-x11-4.2.3/tools/assistant/mainwindow.cpp

but how find now the internal equivalent <span> tag HTML? is this to a fragment?..
