Question about KParts::NavigationExtension::openUrlNotify and KParts::ReadOnlyPart::setUrl()

[Stefano Crocco]

Hello to everyone,
in the documentation for KParts::NavigationExtension::openUrlNotify, it's 
stated that the hosting browser can be query the new URL via 
KParts::Part::url(). I think this means that the openUrlNotify signal must be 
emitted after calling ReadOnlyPart::setUrl(): is this correct?

I'm asking this question because I noticed that in Konqueror WebEnginePart, 
the openUrlNotify signal is emitted when starting loading the URL but setUrl 
is called when it has finished loading. While I don't think this is causing any 
issue right now, I decided that using the expected sequence of operations 
would be better, so I moved the call to setUrl() to when the URL starts 
loading. This has caused other problems, however, so before I start trying 
fixing them I'd like to be sure I'm understanding correctly how things should 
work.

Thanks in advance

Stefano
