Navigation between X windows is surprising #279
Description
Hi! Thanks for this excellent improvement over Neovim!
The feature which caught my attention was the ability to move a vi window into an X window while still being part of the same session. Have been wanting to handle vi and X windows in a single way for a while!
Nevertheless, I encounter a very surprising behaviour. When a vi window is moved into an X window, I can navigate between them using the window manager (WM), but when I try to use the focused window, focus jumps to the one where vi would be "focused". Does this explanation make sense?
I'll give you an example.
- Start fvim on file 1.
:spfile 2. Now there are two vi windows visible in one X window, and the vi focus is on file 2.Ctrl-w ge. Now there are two X windows, each with one vi window.- With the WM, change focus to the X window which has file 1.
- When I type, I'd expect that input goes to file 1, but X window focus jumps to the X window with file 2, where the vi focus was.
Another thing I found surprising was that pressing Ctrl-ww changes the X window focus. I'd have expected for focus to switch between the windows within an X window, not among them.
Is this the intended behaviour?

Hi! I think this is kinda expected behavior, because activating the "X window" does not activate the corresponding vi window (if so, which vi window shall I activate?).
I vaguely remember that fvim will send a focus grab request when switching between multiple grids. If I understand correctly, you want the other way around? That is, send multigrid focus switching when X window focus has changed.
The idea of X window embedding is interesting. We may assemble an IDE-ish environment with this capability :)

Whichever was active on that X window. Would this not be the expected behaviour for any application? The focus stays where it was.
I don't understand what you are saying. Sorry.
I don't understand how this would be X window embedding. I had not considered this.
Currently, there are two "window managers" at play. Regular vim has only its thing but outside vim, there's always one more.
I guess it would be possible to never use vim's WM, and just use X windows for windows. This means that only X's WM could be used to switch between windows. I like it, but I think most vim users would find that jarring.

What if there are multiple? Do I keep track of them?

I'd assume so.
Please, consider if this is something that makes sense. It could be that vim users just don't work like this.
