I'm having a problem with inserting html into a QTextEdit.
Sometimes when I insert text with multiple spans, the order of the spans gets inverted.

Part of the code (on a QTextEdit object):
Qt Code: 
  1. qDebug()<<"html"<<html;
  2.   block=true;
  3.   setHtml(html);
  4.   qDebug()<<"new text"<<toPlainText();
To copy to clipboard, switch view to plain text mode 

The Output:
Qt Code: 
  1. html "<style type="text/css">.ok{color:darkgreen;} .fail{color:darkred;} .cmd{color:darkblue;}</style>test1 test2 <span class="ok">test</span>" 
  2. new text "testtest1 test2 "
To copy to clipboard, switch view to plain text mode 

Does Anyone have an idea how this can be solved?

The complete class:
Qt Code: 
  1. #include <QtGui/qmainwindow.h>
  2. #include <QDebug>
  3. #include <QtGui/qtextdocumentfragment.h>

  15.   win->setCentralWidget(this);
  16.   win->show();
  17. }
