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 ?
