I'll just dump a few thoughts, as I haven't gone through all issues.
First, I think of this problem as morphing druid-win-shell into druid-shell, and shedding Windows dependencies in the process. Since the WinHandler
trait is the main point of interface, it's much the same thing, but not entirely. Likely WindowState
and WindowHandle
will become opaque types.
I'm not sure whether to use a trait-made-concrete (like RenderContext, also gfx-hal is a model of this pattern), or just different impls. One model for the latter is the filesystem in the Rust std lib. One good reason to use the trait is to enable generic code that can use multiple impls, perhaps in the same binary. I think that will be much less important at the "shell" level than drawing.
Keyboard and mouse constants are an issue. I think basing them on the web is a very good idea, as this is well-trodden terrain.
Exactly what should implement the request_quit
method is a good question. We don't really have an object that represents application scope (as opposed to window), but almost certainly we will need it for other things (access to preferences comes to mind). Probably a good time to create that now.
One other thought. Windows uses "dpi" where 96 is nominal, but I think I would rather use a dpi scale where 1.0 is nominal. On Windows, dpi scale = dpi / 96, but on other platforms this wouldn't be strictly true. I also tend to talk about px units, using roughly the same definition as the Web. (Terminology for this is really confusing, on Mac these are called "points", not to be confused with the print unit of the same name).

Closing this, as we've been cross platform for a while, and I think all other relevant details are captured in other issues.
