[webkit-gtk] webkitwebframe control

[Victor Lucero]

Niranjan,

I understand the need of a webextension in the new api, my only problem is that the new api only exposes the first frame and I need a way to (in the extension) got all the frames or a signal that emits on frame creation so we can get all the frames. but looks like a Bug will need to be filed asking for this feature.


Regards.
Victor Lucero.

Simplest example will be writing a small tool that visits a page, wait for page load (UI functionality) and then sets color of an element which can be only done in web process since DOM access is available only in web processes.

Extensions gives you that functionality, but then extensions need to have communication with main process. May be we can have API that allows communication between ui and web process. Example might be send this message to this extension. Then extensions won't have to build their own functionality and many of these problems can be solved by simple messages.
