Rework xi-win to be on top of xi-win-ui about xi-win

[raphlinus]

Nah, I think we can consider this closed by #58, because multiple EditViews is certainly not something that was working before. I've just been committing stuff, but since this is becoming more of a collaborative project we can totally have tracking issues for features we're working on.

I'd like to start work on reworking it into a xi-win-ui app - I can see you've already implemented the ext_listener - should I base my branch off of that one?

[raphlinus]

Yes, or we can just merge the PR; it's mostly up there in case you had any questions or concerns about it.

Glad to have you working on it!

Okay, sounds good.
I have a question in regards to this issue, though. Am I correct to assume that we'll want to remove any dependencies xi-win has directly on winapi/xi-win-shell, and that xi-win can expect all of that behavior to be implemented via xi-win-ui?

EDIT: I've taken a better look at the examples provided, and I can see that it's a healthy mix of both, I'll just get started on rewriting edit_view into a Widget and rendering it via main.rs.

[raphlinus]

Right, there's still a bunch of functionality provided by xi-win-shell (window creation, menus, etc). But EditView itself needs to be pretty much entirely in terms of xi-win-ui, as the event handling, painting, etc., need to be dispatched so they can be shared with other widgets in the window.

An additional point: the file open/save dialog is right now directly on winapi, but this also should be abstracted through the toolkit. That could be a separate project (in the PR that was lost, I used git_hwnd to hack it).

@LiHRaM I might want to work on this again, is that ok? Or if there's something I can do to help, let me know.

[LiHRaM]

@raphlinus Totally fine if you want to work on this. :)

[LiHRaM]

Not sure when we should consider this issue closed, but as you mentioned multiple EditViews, maybe that would be an appropriate point?

It would be possible to start that once #45 and #59 are merged.

[LiHRaM]

Okay, I'll close it then.
