FR: option to move cursor to the center of window when focus changes

[I60R]

I've had such behavior in xmonad and was very happy with it:

1. There's no need to remember where cursor position is
2. It's very handy on floating window
3. In most of cases it reduces path to target that should be clicked

Unfortunately, Sway don't allows something like that.

As far as I see, i3 allows it, but only when output changes: this option is called mouse_warping.

There's also a blog post that describes how to script i3 to do it. But that requires xdotool, which can't move cursor under Wayland.

Anyway, it seems to be a missing focus value for mouse_warping option.

Would you consider to implement it?

[ddevault]

afaik mouse_warping only warps the mouse when you change outputs, which is implemented in sway.

[I60R]

Right, currently it looks like the following:

mouse_warping output|none

But I propose to extend it:

mouse_warping focus|output|none

[ddevault]

Has this been pitched to i3?

[I60R]

Nope.
Should I propose this to i3 first?

[ddevault]

Sure, seems like it'd be useful for both projects.

[I60R]

Ok, I will do that. Thank you for feedback :)

[I60R]

Most likely it wouldn't be supported in i3, see this issue for relevant information.
TLDR: it's hard to maintain under X11.

But situation might be better under Wayland. What do you think about that?

[ddevault]

Sure, sounds good. Let's do it.

I'd be interested in doing this feature as my first contribution. I found the code responsible for warping the cursor on a change to a new workspace here, and I believe the only change needed would be to remove && new_output != last_output from line 714 and make it conditional on the user's settings.

1. Would this be a good first issue?
2. Is this a good solution to the request?

[RyanDwyer]

Would this be a good first issue?

Yep.

Is this a good solution to the request?

Yes, but you'll also need to change the mouse_warping command to accept a container argument (ie. mouse_warping none|container|output). This means config->mouse_warping can't be a boolean any more. Then yeah, the code you highlighted will need to be changed to respect the user's settings.
