Question

I inserted several images into QTextEdit with QTextCursor, now how should I save this entire thing ?

My first thought was to iterate through all positions of QTextCursor, but I didn’t find the proper interface to use.

Sample code in use:

QTextCursor cursor = ui->textEdit->textCursor();
cursor.insertImage(QImage ("/secure/Common/Pictures/icons/gimp.svg"));
ui->textEdit->setTextCursor(cursor);

QTextDocument *document = ui->textEdit->document();
QStringList images;
QTextBlock b = document->begin();
while (b.isValid()) {
    for (QTextBlock::iterator i = b.begin(); !i.atEnd(); ++i) {
        QTextCharFormat format = i.fragment().charFormat();
        bool isImage = format.isImageFormat();
        if (isImage)
        {
            images << format.toImageFormat().name();
            qDebug() << document->resource(QTextDocument::ImageResource,
                                           QUrl(format.toImageFormat().name())).toByteArray().size();
        }
    }
    b = b.next();
}

Quick-and-dirty solution

Just call document->toHtml() and parse the img tags.

Clean solution

Iterate over all the QTextFragment in the text:

QStringList images;
QTextBlock b = document->begin();
while (b.isValid()) {
    for (QTextBlock::iterator i = b.begin(); !i.atEnd(); ++i) {
        QTextCharFormat format = i.fragment().charFormat();
        bool isImage = format.isImageFormat()
        if (isImage)
            images << format.toImageFormat().name();
    }
    b = b.next();
}

Warning: I didn’t test this, it might not even compile.
