How to serialize and deserialize rich text in QTextEdit?

Question

Say I have a structure like this:

class AAA
{
    BBB      bb_member;
    double   dbl_member;
    ....................
}

class BBB
{
    int             in         


        

Answer 1

QTextEdit is a widget, and it doesnt make much sense to write a widget to a file, but we can write the content of the widget (QTextEdit::toHtml()) to the file. When reading from file, we can create a new widget object and initialize it with the contents of the file (QTextEdit::setHtml()).

I must add that it would probably be a better design to store just the richtext data in BBB (as a html QString) as opposed to the QTextEdit itself.
