[webkit-dev] Catching events in JavaScript and the onload event

[Luka Napotnik]

Hello.

Thanks for the reply. So my best bet is to add some sort of a timeout that
will trigger the rendering and hoping that the page is fully loaded? If I
would implement such a signal that triggers itself when all the resources
are 100% ready(DOM + resources) what's the best place to look at?

And .. is there a way to look if the JS engine idles or is executing code?

Greets,
Luka
