In cases like multiple hi-res monitors connected through a USB dock, the
preferred mode can fail to work. Such an output was then ignored by river,
which made it impossible to even set another mode manually.
Sway has been reported to solve this issue, so let's employ their solution
and fall back to another mode if possible.
This fixes the return type of Foo.fromWlrSurface() functions which can
in fact return null in the edge case that the role matches but the
corresponding object has already been destroyed.
Still TODO are:
- Touch support for drags
- Mapping input devices to outputs (necessary for good multi-monitor
touch support)

Some popup menus are not covered by the `overrideRedirectWantsFocus()`
heuristic (e.g. in IntelliJ IDEA), so before focusing an OR window,
its input model should also be checked to ensure that it is able to
take input focus. This appears to fix the popup menus in IntelliJ IDEA,
which would otherwise disappear immediately due to unwanted focus.
- The lifetimes of the Keyboard and Switch structs are now directly
tied to the corresponding InputDevice, which has become a field of
those structs.
- Seat capabilities are now properly updated on removing a keyboard.
These changes align with input device refactoring in upstream wlroots
which will make updating to easier 0.16.0.
Currently we use "switch_device" because that's what the enum variant
happens to be named in zig-wlroots so that it doesn't conflict with the
switch keyword.
This however wasn't really thought through and "switch" makes more sense
to expose to the user.
This was removed a while back because it was buggy and I didn't know
of anyone using it. Since refactoring it is now trivial to implement
and I know of at least one person using it, so I don't mind reviving it.
Until now, Seat.setFocusRaw sent all pressed keys to the client,
including ones that should be eaten. (Try e.g. changing focus to a
nested wlroots compositor with a terminal open to easily see it.)
However, only filtering out the eaten keys is not enough; they were
eaten only once all mappings had been executed. Therefore, the original
function had to be split into one looking up mappings and another
executing them.
Until now, only the event (press/release) for which a mapping was
present got eaten, and the other was passed to the client. From this
commit, a press mapping eats both events and a release mapping eats
nothing (and a press+release combo eats both).
This fixes behavior of some clients that do not make a difference
between press and release (e.g. Firefox with a fullscreen video
exiting fullscreen even on an Esc release event).
Adding the set_override_redirect listener on creation and removing it
on destruction was missed when implementing override redirect state
change handling.
When checking keys for matching mappings, previously we did two checks:
1. Keysyms translated by xkb.
2. Raw keysyms
This commit removes the first check, so only the second is checked.
We're doing this because of strange behavior that xkb shows for some
layouts and keys. When pressing `Shift Space` on some layouts (Swedish
among others), xkb reports `Shift` as consumed. This leads to the case
that we cannot distinguish between `Space` and `Shift Space` presses
when doing a correct translation with xkb.
e.g. `riverctl map -layout 0 normal Super Y spawn foot`
When this mapping is checked against a pressed key, layout 0 will be used to translate the pressed key instead of the currently active layout.
The number denotes to an index of the layouts set with
`XKB_DEFAULT_LAYOUT`.
Currently when the surface under the hidden cursor changes, we
passthrough() which results in the cursor being made visible and giving
pointer focus to the surface under the cursor if any. Obviously this is
not desirable as the cursor is supposed to remain hidden until moved.
This added check prevents this.
From the riverctl.1 man page:
*hide-cursor* *timeout* _timeout_
Hide the cursor if it wasn't moved in the last _timeout_
milliseconds until it is moved again.
The default value is 0, which disables automatically hiding the
cursor. Show the cursor again on any movement.
*hide-cursor* *when-typing* *enabled*|*disabled*
Hide the cursor when pressing any non-modifier key. Show the cursor
again on any movement.
The motivation for this change is to simplify the implementation
and remove a massive footgun that is currently present and causing
UB/crashes. If a layer surface is destroyed in arrangeLayers() then
the code in LayerSurface.handleCommit() after the arrangeLayers()
call accesses free'd memory. This is of course possible to fix,
but it's far simpler to loosen up the protocol implementation a bit.
The new implementation is also in line with what sway and the new
wlroots layer shell helper do and is perfectly valid according to
the protocol.
I have encountered a crash (failing assert) if a view specified a fixed
size less than this minimum, and according to ifreund this behavior was
planned to be removed, anyway.
In particular, this fixes a crash that can happen if a client is made
non-fullscreen and then, while that transaction is ongoing, made
fullscreen again.
Notably, we no longer call both wlr_output_test and wlr_output_commit
when applying an output config, which seems to fix or workaround an
occasional crash since updating to wlroots 0.15.0.
Currently river will place the surface at the top or left edge if
opposing anchors are set without a 0 width/height. Instead, center
the surface between the anchors.
