Bug 13844 – WebKitQt Api doesn't provide any way to append html code to the previous code

• Component: New Bugs
• Status: RESOLVED INVALID

[sebastien le faou]

Description:
If I have an application, like a chat, which uses WebKitQt to render the messages, there are no possibilities to append the new html message codes to the former one.
Indeed, I have to load the entire html code, including the previous messages and the new one.
A function which allow to add new html codes without removing the old one could be a good thing to have

a solution to this bug

I created 2 functions

void openStringAppend(const QString &htmlString)
This function is rendering the html code from a String
and it also append this html code to the previous html (The one which was rendered before)

void closeStringAppend()
This function is supposed to finish the display if the previous function (openStringAppend(...)) is used

I admit I actually liked the KHTML API with regards to this feature. How about

void beginHtml(const QUrl &baseUrl = QUrl());
void appendHtml(const QByteArray &html);
void endHtml();

Once WebKitQt supports a DOM API, you could do this via the Document interface with the open/write/close methods. I think this implementation is not as safe as those with regards to maintaining internal state properly. Even if you want to add it this way, I'd suggest calling open/write/close on the document as the implementation instead of using begin() / end().

r- for wrong implementation and to consider API feedback

This has been fixed with the new DOM API.
