Strange mouse grab on layers with keyboard interactivity

[ettancos]

I think this is probably a bug, found it testing the eww sys tray elkowar/eww#743 (comment)

there are multiple ways to reproduce, enable :focusable in an eww window or just run any layer-shell example like below with keyboard interactivity

I have follow_mouse = 2

the smithay example is with OnDemand but its same with Exclusive too

git clone https://github.com/Smithay/client-toolkit/
cd client_toolkit 
cargo run --release --example simple_layer

expecatation:
mouse events only go to the layer surface if the cursor is over the surface, if its over another surface events go to that other surface

actual:
mouse events seem to go to the layer surface no matter where i click on the screen

sway: mouse clicks go to the intended target surface, not to the layer if mouse is not over the layer surface
does not happen with kb interactivity disabled

so I'm wondering what might keyboard interactivity have to do with mouse events

Well, not a bug per se, intended to be this way. If a layer requests exclusive focus, we grant it exclusive focus.

have to admit, thats a bit surprising to me, the protocol is not very clear on what normal handling is, but in my interpretation pointer events would be handled as any other surface type

the app that wants focus over the entire screen could just set the exclusive zone that way?

use-cases that I'm used to: click away from launcher if i change my mind, fuzzel, wofi, no way to close them without keyboard
also to close tray menu and such

edit: ignore the exclusive zone thing that was stupid, but just have a transparent surface over the screen is one way to do it if the app wants to

Heho,

i think i ran into the same problem (from a somewhat different direction). Im spawning two layer with different sizes:

	Layer level 2 (top):
		Layer 23b2c70: xywh: 3440 0 1200 1920, namespace: eww_dashboard
	Layer level 3 (overlay):
		Layer 2b19ec0: xywh: 3702.5 727 675 466, namespace: rofi

Clicking outside of the rofi namespace does not pass clicks to the eww layer. Is there anything i can do to enable this behavior?

Sidenote: If this is unrelated let me know please. Thus i can remove this comment.

Kind regards
Alexander

If a layer requests exclusive focus, we grant it exclusive focus.

I think this is a bug, because layers are requesting exclusive keyboard focus, not exclusive mouse (or touchscreen) focus.

snippet from the spec:

 <entry name="exclusive" value="1">
        <description summary="request exclusive keyboard focus">
          Request exclusive keyboard focus if this surface is above the shell surface layer.

(My use-case is that I want to use a virtual keyboard like wvkbd on a touchscreen device, and opening bemenu makes it impossible to type)
