the original behavior set fullscreen for all descendents of a container,
which causes issues when firefox is one of those children because it
sends its own set_fullscreen request in response to being fullscreened.
When a tiling container is floated, the focus stack needs to be
appropraitely modified to return the container to its original
position in the tree upon floating disable, like i3.
container_at checks if the position provided matches the currently
focused container with view_container_at as a fast path.
view_container_at checks using the main container geometry, which
includes the titlebar and border area. If a tabbed container is focused,
then positions over unfocused tabs are incorrectly reported as belonging
to the focused container, breaking focus on click.
Add view_container_content_at for use in the focused container fast path
which only tests container content area, and fall back to full workspace
scans for border and titlebar areas.
Closes: https://github.com/swaywm/sway/issues/6074
container_at would maintain the current focus as long as a position was
over one of the container view's surfaces. If an oversized surface was
being clipped, this lead to weird focus behavior.
Instead, use view_container_at for this test, which intersects the
container box before looking at surfaces.
When issuing a focus command on a specific container, users expect to
proceed it even if is hidden by a fullscreen window.
This matches the behavior of i3.
Pending state is currently inlined directly in the container struct,
while the current state is in a state struct. A side-effect of this is
that it is not immediately obvious that pending double-buffered state is
accessed, nor is it obvious what state is double-buffered.
Instead, use the state struct for both current and pending.
workspace_squash is container_flatten in the reverse
direction. Instead of eliminating redundant splits that are
parents of the target container, it eliminates pairs of
redundant H/V splits that are children of the workspace.
Splits are redundant if a con and its grandchild have the
same layout, and the immediate child has the opposite split.
For example, layouts are transformed like:
H[V[H[app1 app2]] app3] -> H[app1 app2 app3]
i3 uses this operation to simplify the tree after moving
heavily nested containers to a higher level in the tree via
an orthogonal move.
In i3, the workspace_layout command does not affect the
workspace layout. Instead, new workspace level containers
are wrapped in the desired layout and the workspace layout
always defaults to the output orientation.
To query whether a container is sticky, checking `con->is_sticky` is
insufficient. `container_is_floating_or_child` must also return true;
this led to a lot of repetition.
This commit introduces `container_is_sticky[_or_child]` functions, and
switches all stickiness checks to use them. (Including ones where the
container is already known to be floating, for consistency.)
Currently, when a floating container with a view is split and
children are added to it, the new views are rendered as tiled,
while the first view stays in floating style.
Here this is addressed by setting the view to tiled as soon
as the container is split, by duplicating the "view part" of
the logic in container_set_floating(..., false). Since the new
container of the view is no longer considered floating, it
makes sense to set the view to tiling at this point.
The view would have to be set back to floating if it was possible
to "unsplit" the container.
This fixes bugs where a floating container would take input way past its
borders when its parent was fullscreen, since the call to
`tiling_container_at` in input/cursor.c's `node_at_coords` did not check
bounds.
See issue #5228. Currently, WL_OUTPUT_SUBPIXEL_NONE is ignored and
CAIRO_ANTIALIAS_SUBPIXEL is still set. This commit checks if subpixel is
set to none and if so, calls set_antialias with CAIRO_ANTIALIAS_GRAY.
This mirrors the functionality in Mako's
[PR261](https://github.com/emersion/mako/pull/261)
In the case of multiple overlapping floating windows, this commit fixes an issue where the wrong window would be focused in response to a cursor if one of the windows came from a different output (overhanging).
The container_at_tabbed and container_at_stacked container were checking
the bounds along the y-axis, but not the x-axis. This made it possible
to cause a segfault for specific resolution, horizontal gap, and
workspace children lengths. The issue is that child_index was -1 and was
resulting in a buffer underflow. Adding the x-axis bound checks for
early returns should prevent this from happening.
When a container was being made fullscreen and it is on the focused
workspace for a seat, focus was being set to the container. However,
when the container was on a non-focused workspace, the focus stack
wasn't being touched. When assigning a fullscreen container to a
workspace or moving a fullscreen container to a different workspace,
this would make it so the fullscreen container was never added to the
focus stack for the workspace thus preventing access to the workspace.
This adds the container to the top of the focus stack, behind the
container on the focused workspace.
This copies the width and height fractions from the container to the
container replacing it. Without setting these values, the container
is treated as a new container and throws off the existing sizing. Since
one container is replacing the other, it makes sense for the sizing to
remain the same.
The documentation for wayland-server.h says:
> Use of this header file is discouraged. Prefer including
> wayland-server-core.h instead, which does not include the server protocol
> header and as such only defines the library PI, excluding the deprecated API
> below.
Replacing wayland-server.h with wayland-server-core.h allows us to drop the
WL_HIDE_DEPRECATED declaration.
This commit si similar to wlroots' ca45f4490ccc ("Remove all wayland-server.h
includes").
Instead of tracking gaps per child apply gaps in two logical places:
1. In tiled containers use the layout code to add the gaps between
windows. This is much simpler and guarantees that the sizing of children
is correct.
2. In the workspace itself apply all the gaps around the edge. Here
we're in the correct position to size inner and outer gaps correctly and
decide on smart gaps in a single location.
Fixes#4296
Instead of using container->width/height as both the input and output
of the layout calculation have container->width_fraction/height_fraction
as the share of the parent this container occupies and calculate the
layout based on that. That way the container arrangement can always be
recalculated even if width/height have been altered by things like
fullscreen.
To do this several parts are reworked:
- The vertical and horizontal arrangement code is ajusted to work with
fractions instead of directly with width/height
- The resize code is then changed to manipulate the fractions when
working on tiled containers.
- Finally the places that manipulated width/height are adjusted to
match. The adjusted parts are container split, swap, and the input
seat code.
It's possible that some parts of the code are now adjusting width and
height only for those to be immediately recalculated. That's harmless
and since non-tiled containers are still sized with width/height
directly it may avoid breaking other corner cases.

Currently container_replace removes the container from the scratchpad
and re-adds it afterwards. For the split commands this results in the
container being send to the scratchpad, which results in a NULL segfault
if the same container should be shown.
Pass an optional workspace to root_scratchpad_add_container, if the
workspace is passed the window will continue to show on the workspace.
If NULL is passed it is sent to the scratchpad.
This was an issue if no other window except the scratchpad container was
on the workspace.
Fixes#4240
When moving a container to become a direct child of the workspace and
the workspace's layout is tabbed or stacked, wrap it in a container
with the same layout. This allows for the following:
- Run `layout tabbed|stacked` on an empty workspace (or use
`workspace_layout tabbed|stacked` in the config)
- Open some views
- Move one of the views in any direction
- Open another view
- The new container should also be `tabbed`/`stacked`
When setting fullscreen on a hidden scratchpad container, there was a
check to see if there was an existing fullscreen container on the
workspace so it could be fullscreen disabled first. Since the workspace
is NULL, it would cause a SIGSEGV. This adds a NULL check to avoid the
crash.
This also changes the behavior of how fullscreen is handled when adding
a container to the scratchpad or changing visibility of a scratchpad
container to match i3's. The behavior is as follows:
- When adding a container to the scratchpad or hiding a container back
into the scratchpad, there is an implicit fullscreen disable
- When setting fullscreen on a container that is hidden in the
scratchpad, it will be fullscreen when shown (and fullscreen disabled
when hidden as stated above)
- When setting fullscreen global on a container that is hidden in the
scratchpad, it will be shown immediately as fullscreen global. The
container is not moved to a workspace and remains in the
scratchpad. The container will be visible until fullscreen disabled
or killed. Since the container is in the scratchpad, running
`scratchpad show` or `move container to scratchpad` will have no
effect
This also changes `container_replace` to transfer fullscreen and
scratchpad status.
This matches i3's behavior of setting scratchpad containers to 50% of
the workspace's width and 75% of the workspace's height, bound by the
minimum and maximum floating width/height.
This fixes the sizing of floating non-view containers. On master, the
floater will get set to the maximum width and height, which by default
is the entire output layout. When setting a non-view container to
floating, this will set a sane default size of 50% of the workspace
width and 75% of the workspace height, or whatever the closest is that
the minimum and maximum floating width/height values allow for. On all
future calls to `floating_natural_resize`, the width and height will be
kept unless they need to be changed to respect the min/max floating
width/height values.
This fixes a crash in `container_init_floating` when a xwayland view
sends a configure request while in the scratchpad.
`container_init_floating` gets called so the configured minimum and
maximum sizes gets respected when resizing to the requested size. Since
the workspace was NULL, it would SIGSEGV when attempting to get the
workspace's output for the output box retrieval.
This extracts the resizing portion of `container_init_floating` into a
separate function. If the container is in the scratchpad, it will just
be resized and skip the centering.
Additionally, `container_init_floating` has been renamed to
`container_floating_resize_and_center` to more accurately describe what
it does.
Since the NOOP output has no size, the minimum floating size is greater
than the workspace size for the NOOP output. In this case, the floater
gets centered in the output instead of the workspace. However, the
NOOP output is not part of the output layout and thus has a NULL box.
Attempting to access the properties of this box was causing a segfault.
This fixes the issue by just setting the floater's box to all zeroes
when mapping on the NOOP output. When the workspace gets moved from the
NOOP output to a new output, any floater whose width or height is zero
or has an x or y location outside of the output, gets passed to
`container_init_floating` again. This will then set the appropriate
size and centering. For any floater that has a valid size and location,
they are preserved.
If a container gets mapped as fullscreen and set to floating by
criteria, the size and location are never set for the floating
container. This adds a check in container_fullscreen_disable for a
width or height of 0 and calls container_init_floating
This changes the way zero (which is the default) is interpreted for both
the width and height of `floating_maximum_size`. It now refers to the
width and height of the entire output layout, which matches i3's
behavior.
This also removes duplicated code to calculate the floating constraints
in three files. Before this, `container_init_floating` used two-thirds
of the workspace width/height as the max and the entire workspace
width/height was used everywhere else. Now, all callers use a single
function `floating_calculate_constraints`.
container_floating_move_to_center and container_fullscreen_disable were
calling recursively when the container spawned as a fullscreen floating
container (via for_window). Such a window now doesn't crash sway anymore
but is still configured with a wrong, zero size, making it not directly
usable.
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.
It is possible to make the title bars have a zero pixel height while
stacked, by using a blank font and no padding. This causes a division by
zero when attempting to calculate the child index in
container_at_stacked, which then results in a segfault when attempting
to access the child at that bad index (INT_MIN). This just skips the
check to see if the cursor is over a title bar of a child of a stacked
container when the title bar height is zero since there will be no title
bars.
