    I have a problem, I insert a QTextObjectInterface object in QTextEdit control, I want to get the location of the object in the text, how to get its area.

    Besides, I want to insert an input region similar to QTextEdit in the rich text, and how to implement it.

      //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 ?
