I noticed these events (nsIDOMxxxEvent) yesterday but had no idea how I
could register my application to listen to them. I have an instance of
nsIWebBrowser and nsIWebBrowserChrome. Using queryInterface I can get
browser chrome's nsIBaseWindow - but none of these classes has any
method like addEventListener() or something like this.
As for browser scrolling - I don't need to receive scrolling events (may
be need them later), but want the browser to react on them itself. For
example, if I click a link inside a browser, it follows that page
automatically without any actions in my code, but for scrolling this is
not a case. Do I need to listen to key/mouse events myself and then tell
the browser to perform what I need?
If you can send me some short example it would be fine. Also, don't you
know is there any tutorial about mozilla UI (windows, widgets, events,
etc.) available? All I can find in the web is descriptions of Mozilla
interfaces, not how to use them together:(
Thanks,
Artem

I'm embedding Mozilla-based browser into my Java application using
JavaXPCOM, on Windows. One of the first difficulties I met is that
browser doesn't react on mouse wheel, thoug its scrollbar is present.
My container implements these interfaces: nsIWebBrowserChrome,
nsIWebBrowserChromeFocus, nsIEmbeddingSiteWindow. What should I do to
enable mouse wheel in embedded browser?
Another question is: is it possible to get mouse and key events
occuring in browser? I don't need them right now but they can be
useful in my app later.
Thanks,

Artem,
I'm not real familiar with Java, but to receive events in my C++ app, I
implement the nsIDOMEventListener interface. You have to setup the
events you want notification from for this to work, but it's not that
hard. If you get to the point you need code examples, I can provide you
some in C++.
If you want to DISPATCH key or mouse events to an element, take a look at:
nsIDOMDocumentEvent
nsIDOMEvent
nsIEventTarget
nsIDOMKeyEvent
nsIDOMMouseEvent
Again, if you need some code examples, I can provide you with a few.
Hope this helps!
