I have reimplement QTextBrowser to paste image && load on a image tag <img> on QTextDocument

But i like to work on vector svg image format format how i can discovery this Mime?
&& save on disc format one copy as svg format & one as png?


Qt Code: 
  1. bool QVimedit::canInsertFromMimeData ( const QMimeData * source )
  2. {
  3.     return QTextEdit::canInsertFromMimeData(source);
  4.      qDebug() << "### insertFromMimeData 1  ";
  5. }
  6. void QVimedit::insertFromMimeData ( const QMimeData * source )
  7. {
  8.  
  9.     qDebug() << "### insertFromMimeData 2  ";
  10.  
  11.     if ( source->hasImage() ) {
  12.          numerobase++;
  13.          const  QString nuovaim = QString("%2/image_%1.png").arg(numerobase).arg(QDir::homePath());
  14.          QImage images = qvariant_cast<QImage>(source->imageData());
  15.          bool salvato = images.save(nuovaim,"PNG",100);
  16.          //////////////////qDebug() << "### salvato 1/0  " << salvato;
  17.           emit TakeImage(nuovaim);
  18.          return;
  19.     }
  20.     QTextEdit::insertFromMimeData(source);
  21.     if ( source->formats().contains("text/html") ) {
  22.         qDebug() << "### incomming paste text/html  ";
  23.         emit IncommingHTML();
  24.     }
  25. }
