<description summary="limit input focus to a set of surfaces">
This protocol allows clients to limit input focus to a specific set
of surfaces and receive a notification when the limiter is removed as
detailed below.

<interface name="hyprland_focus_grab_manager_v1" version="1">
<description summary="manager for focus grab objects">
This interface allows a client to create surface grab objects.

<interface name="hyprland_focus_grab_v1" version="1">
<description summary="input focus limiter">
This interface restricts input focus to a specified whitelist of
surfaces as long as the focus grab object exists and has at least
one comitted surface.
Mouse and touch events inside a whitelisted surface will be passed
to the surface normally, while events outside of a whitelisted surface
will clear the grab object. Keyboard events will be passed to the client
and a compositor-picked surface in the whitelist will receive a
wl_keyboard::enter event if a whitelisted surface is not already entered.
Upon meeting implementation-defined criteria usually meaning a mouse or
touch input outside of any whitelisted surfaces, the compositor will
clear the whitelist, rendering the grab inert and sending the cleared
event. The same will happen if another focus grab or similar action
is started at the compositor's discretion.
</description>
<request name="add_surface">
<description summary="add a surface to the focus whitelist">
Add a surface to the whitelist. Destroying the surface is treated the
same as an explicit call to remove_surface and duplicate additions are
ignored.
Does not take effect until commit is called.

</request>
<request name="remove_surface">
<description summary="remove a surface from the focus whitelist">
Remove a surface from the whitelist. Destroying the surface is treated
the same as an explicit call to this function.
If the grab was active and the removed surface was entered by the
keyboard, another surface will be entered on commit.
Does not take effect until commit is called.

<request name="commit">
<description summary="commit the focus whitelist">
Commit pending changes to the surface whitelist.
If the list previously had no entries and now has at least one, the grab
will start. If it previously had entries and now has none, the grab will
become inert.
