Attached patch refactor patch (obsolete) (deleted) — Splinter Review
most of this patch is working around places where we access GeckoApp.mAppContext from outside GeckoApp. I eventually want to make GeckoApp.mAppContext private and create interfaces for anything in GeckoApp that needs to be accessed. The /*FIXME*/'s are places where we will need those interfaces. There are others but this is the minimal change to get a WebView working.

This renames GeckoApp.mAppContext to GeckoApp.sAppContext (since it is static after all) and makes it private. It also adds a method to GeckoAppShell called getGeckoInterface() which right now returns a GeckoApp. The next step is to create a minimal interface for it to return.

There are a few things I think you should change ("Change:"). The rest are good fodder for followups. Looking at the code affected by the patch makes it easy to see some "problem areas" I think we should address in the near future. Please get a Try run. We'll need to do a lot of testing too, just to be sure nothing got borked.

I think we can lift this part out of GeckoApp and into LayerView (or somewhere else in gfx/) now and then it wouldn't need to be duplicated across GeckoApp and this new GeckoView. Also, WebAppImpl disables overscroll by calling setOverScrollMode(View.OVER_SCROLL_NEVER) which is also probably something you want in a standalone GeckoView. It probably makes more sense to make that the default behaviour and modify BrowserApp to turn on overscroll explicitly. I can provide patches for that.
This moves the code to dispatch touch events from GeckoApp into LayerView so that it doesn't need to be duplicated. I left the overscroll stuff as-is because in the end changing that behaviour didn't actually simplify the code, just moved it around.

Comment on attachment 755534 [details] [diff] [review] Move the touch dispatching into LayerView Review of attachment 755534 [details] [diff] [review]: ----------------------------------------------------------------- this is good. Another option is to move the logic into GeckoView and have GeckoApp use the GeckoView. Thoughts?
Attachment #755534 - Flags: review?(blassey.bugs) → review+
I prefer doing this because it does a better job of encapsulating this behaviour with other code that depends on it. Ideally I also want to move the GeckoAppShell.notifyDefaultPrevented function into gfx/ somewhere as well. This code will not be needed once we switch over to the APZC so it doesn't make sense to expose it to GeckoView.

A second GeckoView would be like a second window. We'd only have one gecko thread to spin up. We would need to check checkLaunchState(GeckoThread.LaunchState.GeckoRunning) and trigger the handler code though. > > >+ sGeckoThread = new GeckoThread(intent, "http://mit.edu"); > > OMG good test site > > >+ public void handleMessage(String event, JSONObject message) { > > >+ Tab tab = tabs.loadUrl("http://mit.edu", Tabs.LOADURL_NEW_TAB); > >+ int id = tab.getId(); > >+ tabs.selectTab(id); > > >+ Tab selectedTab = Tabs.getInstance().getSelectedTab(); > > Can't you use the tab you loaded above?
