Bill asked:Sent: Sunday, 10 January 2016 1:25 AM Next question: How do I save and restore to HTML?Hi Bill, I can't help with the saving. But we display html documents with<object> tags and replace them with QWidgets:
The HTML representation is kind of an abomination and ultimately I would like to have more control, so I just wrote my own XML read/write code at the cost of ~250 LOC. Thanks Bill
- We fetch all of the text using codecForHtml. - Search for<object> tags, parse the arguments and replace the tags with plain "[[object]]" markers, building up a list of their locations. - Set the modified html into a QTextBrowser. - Loop over the locations (in reverse order) and create a widget for each object, parented by the browser, remove the text and insert the ObjectReplacementCharacter. There are lots of painful gotchas to work around - moving the widgets to the correct location, hiding the widgets until required, rendering with the correct scale when printing, etc. The document object interface is pretty stunted - in Qt4 I don't believe there was a virtual hook into the html saving process to handle the special characters. I suspect you'll need to modify the Qt sources, or create a copy of the document, and do the reverse of the steps above. Good luck!
