//register object
QObject *fillBlankInterface = new HHFillIntheBlanks;
fillBlankInterface->setParent(this);document->documentLayout()->registerHandler(FillBlankFormat, fillBlankInterface);// insert a object
QTextCharFormat fillBlankCharFormat;
fillBlankCharFormat.setProperty(FillBlankFormatId, id);
fillBlankCharFormat.setProperty(FillBlankFormatValue, answer);
fillBlankCharFormat.setObjectType(FillBlankFormat);QTextCursor cursor = textCursor(); cursor.insertText(QString(QChar::ObjectReplacementCharacter), fillBlankCharFormat);setTextCursor(cursor);
// object size
QSizeF HHFillIntheBlanks::intrinsicSize(QTextDocument *doc, int posInDocument, const QTextFormat &format)
{
QFontMetrics metriecs(format.toCharFormat().font());
return QSizeF( metriecs.width(QStringLiteral("啊"))*10 , metriecs.capHeight());

Hi and welcome to devnet,
How are you inserting your custom text object ?
