Hi,
I'm writing a Konqueror plugin that needs to perform operations every
time the DOM tree of a page changes. As DOM tree changes generally occur
after a network request (an AJAX web-page fetched data on the Internet,
on a plain HTML page has been loaded), I tried to use the started(KJob
*) signal of KParts::ReadOnlyPart. When a KJob is given as parameter
(the parameter can also be NULL), I also react on the finished() signal
of the job.
This works for some web-pages (static HTML and Yahoo! Mail Neo), but the
problem is that GMail does not seem to trigger the signal when I browse
my emails. By using HTTP-Fox in Firefox, I can see that every action
causes a network request to be performed, but the started(KJob *) signal
is never fired. If you perform a search on DuckDuckGo and scroll the
page, new results are appended to it (they are fetched from the
network), but no signal is triggered.
Is there a mean to get a signal whenever the DOM tree of a document
changes ? The best would be that the solution works equally well for
web-pages rendered using KHTML or kdewebkit, but if hacks are needed to
make one engine or the other work, I would also be happy.
