Offscreen Rendering

Hello, we are using an old embedded 1.5 FF/XULRunner in our eyetracked web browser. Now it's time for an update to FF3... but I see that the nsIViewManager::RenderOffscreen function exists no more, has been moved to nsIPresShell, renamed to RenderDocument and now gets a gfxContext instead of an

Whooops... I made a new post, it was intended as a reply to an older post. Sorry. In any case: we are talking about offscreen rendering, i.e. getting the pixels of a rendered HTML page. THIS was the correct post:

Re: Question about synthetic mouse events, click and why this sometime fails.

Hi Boris, first of all thanks for your help, as always fundamental. Is your listener bubbling or capturing?  If the former, are the sites stopping propagation of the click event when they handle it? err... I was bubbling. In fact, if I switch to capture mode, I see all the events. Now at

So this site depends on the background catching the click event.  In your setup, are you drawing backgrounds? Nope. I do NOT modify in any way the DOM, just parse it to get interesting nodes and their position, in order to send them synthetic clicks when needed. Also, I listen for DOM

Your code needs to be called on anchor scrolls?   yep, also. everytime something moves, I need to re-register updated areas and positions in order for everything to be eye-trackable. If so, OnLocationChange is the only notification you'll get. ok. I'll work it out. thanks!

Any DIV or block-level element in HTML, smaller or larger, can have scrollbars and can scroll the inner content. Now if such a DIV is set to always be as large as the window and holds the page's content, then what you really need to scroll is one of the DIV elements in your page. After
