Currently, when tablet input exits a window during an implicit grab, it
passes focus to another window.
For instance, this is problematic when trying to drag a scrollbar, and
exiting the window — the scrollbar motion stops. Additionally,
without `focus_follows_mouse no`, the tablet passes focus to whatever
surface it goes over regardless of if there is an active implicit.
If the tablet is over a surface that does not bind tablet handlers, sway
will fall back to pointer emulation, and all of this works fine. It
probably should have consistent behavior between emulated and
not-emulated input, though.
This commit adds a condition for entering seatop_down when a tablet's
tool tip goes down, and exiting when it goes up. Since events won't be
routed through seatop_default, this prevents windows losing focus during
implicit grabs.
Closes#5302.
This is a small cleanup commit for removing `sway_tablet` parameters
from functions that already accept `sway_tablet_tool`, since the tablet
reference can be accessed through `tool->tablet`.
This commit renames `motion` and `axis` handlers to `pointer_motion` and
`pointer_axis`, respectively, to disambiguate them from their tablet
(and future touch) handlers. `button` is left as-is, as it is generic
across input devices.
This commit moves tablet motion logic into a seatop handler.
As a side-effect of seatop implementations being able to receive
tablet motion events, fixes#5232.
This commit refactors `cursor_rebase` into `cursor_update_image`, and
moves sending pointer events to the two existing call sites. This will
enable this code to be reused for tablets.

Fixes#4819.
This commit ensures that `seat_set_focus` is called to transfer focus
when a window is selected via a pen. Previously, it would race with
`node_at_coords`, and only properly transfer focus if its returned
`surface` was NULL.
This commit refactors `cursor_handle_activity` to also take the idle
source, so that it can be reused for tablet and touch activity.
Previously, the timeouts would be tracked, but the cursor would never be
un-hidden for anything but pointers.
Fixes#5169.
If we started holding the tool tip down on a surface that accepts tablet
v2, we should notify that surface if it gets released over a surface
that doesn't support v2.
Since GTK supports tablet v2, this fixes the common case of starting a
drag over a GTK surface (e.g. scrollbar) and releasing it outside (e.g.
over the gaps between sway containers, or in a terminal).
Refs #5230.
This fixes a crash when attempting to listen to a signal on a NULL
cursor image surface. If the surface is NULL, the listener is just
reinitialized using wl_list_init.
This adds a listener for the destroy event of the cursor image surface.
This prevents a use-after-free when the last visible image surface is
freed, there has not been a new cursor set, and the cursor is reshown.
This adds seat configuration options which can be used to configure what
events affect the idle behavior of sway.
An example use-case is mobile devices: you would remove touch from the
list of idle_wake events. This allows the phone to stay on while you're
actively using it, but doesn't wake from idle on touch events while it's
sleeping in your pocket.
Some wayland clients (mostly GTK3 apps) like eog or evince support
gestures like pinch-to-zoom. These gestures are given to clients
via the pointer_gestures_v1 protocol. This is already supported in
wlroots, so we just need to hook up the events here in sway.
Fixes#4724
Sway has basic support for drawing tablets, but does not expose
properties such as pressure sensitivity. This implements the wlr tablet
v2 protocol, providing tablet events to Wayland clients.
This just adds a small quality of life improvement to the cursor hiding
functionality. The cursor will no longer be hidden unless all buttons
are released.
This introduces a `default` seat operation which is used when no mouse
buttons are being held. This means there is now always a seat operation
in progress. It allows us to separate `default` code from the standard
cursor management code.
The sway_seatop_impl struct has gained callbacks `axis`, `rebase` and
`end`, and lost callbacks `finish` and `abort`. `axis` and `rebase` are
only used by the default seatop. `end` is called when a seatop is being
replaced by another one and allows the seatop to free any resources,
though no seatop currently needs to do this. `finish` is no longer
required, as each seatop can gracefully finish in their `button`
callback. And `abort` is not needed, as calling `end` would achieve the
same thing. The struct has also gained a bool named allow_set_cursor
which allows the client to set a new cursor during `default` and `down`
seatops.
Seatops would previously store which button they were started with and
stop when that button was released. This behaviour is changed so that it
only ends once all buttons are released. So you can start a drag with
$mod+left, then click and hold right, release left and it'll continue
dragging while the right button is held.
The motion callback now accepts dx and dy. Most seatops don't use this
as they store the cursor position when the seatop is started and compare
it with the current cursor position. This approach doesn't make sense
for the default seatop though, hence why dx and dy are needed.
The pressed_buttons array has been moved from the sway_cursor struct to
the default seatop's data. This is only used for the default seatop to
check bindings. The total pressed button count remains in the
sway_cursor struct though, because all the other seatops check it to
know if they should end.
The `down` seatop no longer has a `moved` property. This was used to
track if the cursor moved and to recheck focus_follows_mouse, but seems
to work without it.
The logic for focus_follows_mouse has been refactored. As part of this
I've removed the call to wlr_seat_keyboard_has_grab as we don't appear
to use keyboard grabs.
The functions for handling relative motion, absolute motion and tool
axis have been changed. Previously the handler functions were
handle_cursor_motion, handle_cursor_motion_absolute and
handle_tool_axis. The latter two both called cursor_motion_absolute.
Both handle_cursor_motion and cursor_motion_absolute did very similar
things. These are now simplified into three handlers and a single common
function called cursor_motion. All three handlers call cursor_motion. As
cursor_motion works with relative distances, the absolute and tool axis
handlers convert them to relative first.
By the time seatop_allows_events was called, seatop_impl was already
NULL, causing the function to always return false. This means a press
event was sent to clients without a corresponding release event.
This patch moves the call to seatop_finish to after the
seatop_allows_events check.
It turns out sending button events during all seat operations is not
desirable. This patch introduces a new property
`seatop_impl.allows_events` which allows each operation to define
whether button events should be passed to the surface or not.
The `down` seat operation is the only one that supports this. As all the
other seatops don't support it, the calls to seat_pointer_notify_button
prior to starting them have been removed.
If two cursor buttons are pressed at the same time, the client will now
be notified of the second button press.
The main reason for not sending the concurrent presses was due to an
early return in dispatch_cursor_button if a seatop is in progress. This
patch makes it call seat_pointer_notify_button prior to returning. But
it also has to make sure there's not a mismatch in events such as a
release without a press.
Prior to this patch, the down seatop would send press and release events
in its begin and finish functions. No other seatops did this. A press
event would be sent prior to starting tiling drag, but never an
associated release.
After this patch, no seatops send their own press or release events. We
send them prior to calling the seatop begin functions, then the first
part of dispatch_cursor_button handles all presses during seatops and
when releasing the seatop.
All seat operations except "down" eat the button pressed event and don't send
it to clients. Thus, when ending such seat operations we shouldn't send the
button released event.
This commit moves the logic used to send pressed/released into the "down"
operation.
This modifies the places where output_get_active_workspace is called to
handle a NULL result. Some places already handled it and did not need a
change, some just have guard off code blocks, others return errors, and
some have sway_asserts since the case should never happen. A lot of this
is probably just safety precautions since they probably will never be
called when `output_get_active_workspace` is not fully configured with a
workspace.
In handle_cursor_motion, the timestamp passed to
`wlr_relative_pointer_manager_v1_send_relative_motion` should be
microseconds (not milliseconds) according to relative-pointer-v1 spec.
